It uses a PIC mcu to convert the signals and allow for plug-play operation.
This means there is NO need to use modified XBMC or any other modifications are needed. The Adapter converts a parallel LCD into a SPI lcd for use on the xenium.
Even includes support for software contrast and backlight (no more pot tweaking)
I will be posting more information on my website as I have it available.
Check it out at http://cheaplpc.com/xenlcd/
It is 3.2cm x 1.7 cm, which means it can hide anywhere. All components are SMT. So it is very thin as well.
Doing this almost at cost, so dont expect anything but the best that my hands can make.
Looking at around $15 and shipping.
Iam taking orders on the 10 prototypes i have to help finance the initial batch. Contact me if you are interested in a prototype.
I will keep this thread and my website updated as I get more ahead.
Jul 9 - Received the first prototype from factory. It looks great.
First picture (IMG:http://cheaplpc.com/xenlcd/proto.jpg)
Jul 12 - Received the SPI connectors today. If you need the connector for your own project or whatever reason, contact me and I would be more than happy to sell you as many as you need.
Dont forget, you can contact me any time via email at [email protected]

Finally got the PIC chips programming and the code worked as expected. There is NO synch problems at all with the PIC solution.
As an added bonus to using the PIC, you have some 10-15 extra i/o lines to do with as you please. That means the PIC can be used to also control the LCD baclight, and contrast, as well as control some of the I/O pins for whatever you want. Think of it like the CrystalFonts lcd on steroids.
And its only running at 4mhz.
I will release more info later today.
VERY Excited.

Two ways to go about it
Have the PIC emulate the commands of the CrystalFontz lcd such that there is minimal changes needed for XBMC, and thus the other apps that already may have LCD support
OR
Go with completely new routines requiring a 'new' LCD if you will in XBMC, just a whole different setting. But this allows the greatest flexibility because its fully customizable and can have what i said earlier about the extra i/o and such.
OR
A variant of both, Have it use the Smartxx method of using the LCD, and only requiring 6 very quick changes to XBMC for it to work. Also the simplest to implement in the code. I may go this route for the public version.
Iam thinking, and trying to see if I can come up with all 3 in 1, using software control.
Post by: greengiant on June 19, 2004, 01:45:00 PM
The smartxx way is the easiest, 1 function in xbmc needs to be changed, the display out, and the PIC code is quite simple.
The ones that act as a SPI lcds, are a bit more complicated but its done.
I think it wont be to hard to make it switchable with a dip switch or solder pads. So it should not be any trouble to have all 3 ways.
And if anyone has any ideas or request let me know, lots of room for expansion.
An idea I had, was also to use a charge pump to up the 3.3v to 5v, so you dont have to use any adapters or anything else. Ill see how my charge pump circuit goes, hopefully not too expensvie.

At the moment Iam going to need to have a prototype made of the PCB i posted above. My current manufacturer can make it but there is a delay of about 1-2 weeks, with this prroject iam hoping to make some 5 prototypes and have the pcb made in a week at most. Im willing to pay, hopefully not too much. The cheapest quick prototyping i have found, is about $20/board in 5 days. Please let me know if you can be of assistance.
Or if anyone else.
Thanks.
Ive been thinking, I may end up having a "send me 3 PIC, get the kit free" type of deal. That way you order samples from Microchip (free) send em to me, and I send you a complete kit free. Thats assuming I also get normal orders to offset the cost of the boards and parts, or I may do a "send in 2 PIC's + $2 and get a kit"
Some sort of deal for low cost people. Even though $10-15 is already cheap as it is.
Also,
I have found a source of LCD's. 100 20x4 for $6/each or 100 16x2 for $5/each
I may do complete LCD+Adapter kits, if theres demand for the complete unit.

Just a question from a n00b
Post by: greengiant on June 21, 2004, 10:23:00 AM
But I can program the chip for you, if your a do it yourselfer.
Post by: greengiant on June 21, 2004, 06:55:00 PM
1, Smartxx way
2, Crystal Fonts emulation
With the command set used by Crystal Fonts in their LCDs you can set the Contrast and Backlight from commands.
So, the support is there, and the PCB itself has 8 extra i/o for future things. 2 of those is the LCD contrast and LCD backlight.
The backlight off course is made for those LCD's that use an LED backlight that only requires GND and 5V. Those that require a negative voltage or use special lights may not work thru the software control, but with a relay or something of the sort (possibly a transistor) it can at least be on/off from software.
Contrast Iam working on fully implementing it in the code, thinking exactly how to do it via hardware, but I should have it fully done sometime tonight or tommorow.
At the moment it is simply connected via a resistor to GND.
And off course there is the 8 i/o for any future stuff. Mind you the pic does have to be re-programed with the new code for the new features, but that will be available for free.
The PIC is a 16F876A that will be used. Iam not exactly sure how it will go if completely free as I said before "3 for free kit" or if it will be "1/2 + lil $ for kit" but I will have something for those who want as cheap as possible.
The lcds is more of an investment so that I will look after the circuit board is complete.
Post by: moobar on June 21, 2004, 10:03:00 PM
You could try to implement a HDD and LAN signal with 2 extra wires tied to vcc and the HDD and LAN idle lines to a couple of inputs.
Use maybe the upper-right 2 characters (0x12 and 0x13) of an 20x? display for example. Maybe use a character with alot of dots so its easy to see, or write a custom one to CGRAM.
Have one dip that the user can either close or open to specify he is using 16x? or a 20x? display so you can get the upper-right position correct.
If the user chooses not to use this feature, no harm, the inputs are tied high.
The input polling cycles wont eat to much but the writing to LCD might.
Post by: mlwood37 on June 22, 2004, 09:16:00 AM
. Thats what you get for being a cheep skate lol.
I would be willing to pay upwards of £15.00 for one in a kit form inculding the wires to mount it at the front of the xbox.
Glad to see such skills in the scene from some very clever PPL. Ill be whaching you space as son as you ready to do either Beta testing or selling the product full ill be there waiting with a cheque.
hopefully you will be able to send these to the UK. hint hint.
Post by: greengiant on June 22, 2004, 11:35:00 AM
kingmt, yes thats how it will ship. There will be diff versions, depending on your skills. One will have the Xen connector + wires soldered to the board ready for install.
Its looking at around $15 and $4 for shipping anywhere (worldwide) and handling is included.

Backlight will most likely also be PWM+Other in order to control the much higher source of the backlights.
ScreenSaver... mayby. Ill see bout that.
Post by: greengiant on June 25, 2004, 02:21:00 AM
Still working on some sort of custom boot logo that is programmable (right now boot logo is pre-programed in the chip)
As well as the screen saver idea.
Prototype is being made and should arrive in the next few days.
Post by: moobar on June 25, 2004, 02:22:00 PM
Ive got a bunch of different size LCDs in my junk bin, question is what is the smallest size that will work so far with XBMC?
I'll probably try to install a 16x2 or 20x2 to the case, a 40x? seems way to big to fit without completely butchering the case.
I wanted to make an SPI extension cable of some sort which would contain the Xenium at one end and your gadget at the other end so I could hide the Xbox in one area but with the display mounted and visible in another area. What would be the minimal connections from the Xenium to the gadget? G, V5, SOUT, SCLK?
Post by: greengiant on June 25, 2004, 06:41:00 PM
1 The adapter will be close to the xenium, and the wires will run some 20-30cm to the LCD
2 The adapter will be close the lcd, and the wires will run some 20-30cm to the xenium.
Oviously the 2nd solution is better as it uses less wire.
The wires for the SPI are
SDO CLK GND VCC
But do note 5v is also needed, the SPI does not provide for this.
There are a few methods, LPC port, USB connector, motherboard, hdd connector.
I will probably be using the HDD connector method with an adapter, or the same way I do with the XIR, have a thick wire that inserts into the molex adapter on the motherboard.
The wires for the LCD Are
D4 D5 D6 D7 RS VCC VEE RW <something> <Something> led+ led-
In all it is 12 wires, but RW and LED+ are all repeats of other wires, so the minimal from adapter to LCD is 10 wires.
For reference:
1 VSS GND
2 VDD V+ 5v
3 Vo (Contrast) Check datasheet (0-20k resistor to GND)
4 RS
5 R/W GND
6 E
7 D0
8 D1
9 D2
10 D3
11 D4
12 D5
13 D6
14 D7
15 BGLED Optional-Refer to your datasheet (GND/V+)
16 BGLED Optional-Refer to your datasheet (GND/V+)

While not something that would sell very good but would be a fun project for me.What kind of SPI clock rates are we talking? I know I got some TX/RX parts around here that can handle about 4800bps.
Post by: greengiant on June 26, 2004, 12:34:00 AM
The wireless idea is cool. Not nessesarly with batteries, but just the wireless for the data. The ideal would be a car. You stick the xbox in the trunk, and the LCD is wired up only for power in the front of the car. Simple cigarette lighter adapter will do the trick. Then the data itself is sent from the back to the front. No need for wires or any messy stuff.
BUT, the cheap wireless Ive seen can come to around $10 for a pair, and isnt too releiabled. A better ones ive used, can run upwars of $20pair
So it depends on the need of the user if it can really be a good thing to use the wireless or not. If people are interested in this, I will look into it as it is very easy to implement.
Post by: mlwood37 on June 26, 2004, 03:33:00 AM
I have a xbox in the footwell of my car and a 600 watt inverter attached to it.
The xbox is modded with the xenium and a 300 gig HD.
There are 3 x 7 1/2" wide screen tvs attached to it.
Now with the car turned off (not running) the xbox and TVs runs fine and i have no problems.
When i start the car and start running the inverter soft turns off and then comes back on ( i think). Then i turn the xbox on. The problem i have is when the car stop at a light and i go off again the xbox suddleny just stops working and sort of just Humms. But i cannot get it to work unless i Turn off the inverter and then turn it back up again.
This is a bit bad due i cannot just jump out of the car and open the foot wells and re start the inverter every time i have to come to a crner or a traffic light.
Is there a way to solve this problem as its very annoying.
Should i use a seond battery and use a relay to the sceond battry and just run the xbox of the second battery.
I dont get any interfeance off the xbox due to me adding inline suppressers to my xbox on the 12V and 5v line with in the xbox its self.
Post by: greengiant on June 26, 2004, 02:51:00 PM
When you said the xbox stops when the car stops at an intersection, that is when the car is at idle, producing the least amount of power. It may be possible the inverter is not able to provide enought power to the xbox and such.
What rating is the inverter your using ?
You may want to try a different inverter, a more powerfull one.
Also check other devices that donot use the same amount of power, to see if the problem is that the xbox is running out of power and thus it becomes unstable.
Post by: mlwood37 on June 26, 2004, 03:15:00 PM
.p.s the inverter is on this page = http://www.maplin.co...n=F&modulecode=
its the N66AU - Dam its gone down By £40 ---- i payed £90 ARRRRRR
Post by: greengiant on June 28, 2004, 02:51:00 AM
i dont know if a battery + inverter will be best option.
Since the xbox does not use the power at 112v directly, it dowconverts.
You can try and find car adapters made for computers, ATX connector that plugs directly into 12v or can be wired to battery. That way your not loosing power in the upconvert/downconvert.
How long do you plan to run the xbox on the battery ?
"(proves your add at the bottem of your nic works)."
I dont have an ad tag on my posts. I hate people that have LONG signatures, so every time they post it makes the thread HUGE with clutter.
Post by: greengiant on June 28, 2004, 02:52:00 AM
Also may have found a very nice manufacturer/supplier of parts which can possibly allow me to make the $15 mark I promised.
Good and Semi-Good news,
Iam starting to get replies from JST distributers about the connectors.
I found one that has the Crimps at a cheaper price, but its still a reel of 23k (or about $300) which is about $100 less than the other place. theyr connectors are more expensive, 0.23. So i may do a mix between these and the others, these for the crimps and the other for the connectors.
BUT they do have the IDC version connector with no minimum, but the connector is about 3x what the crimp version (or 10x from the other dis)
But it gets cheaper in 100's
So i may opt to go with IDC.
Once I get samples I will be able to say more if its worth the crimp over IDC. Also as I get more replies I will post info.

Im putting together my external case that will house a 20x4 LCD and your gadget. Currently I have about 0.35" clearance after the LCD is installed.
First project is to have it hard-wired with some quick disconnect cables.
Second project will be the wireless version with a programable remote (LCD + your gadget + Linx receiver + stripped down programmable remote + 4AAA) Of course this version will be a giant of a case to house it all in so clearance isnt a prob. The idea behind this is to have it sitting on the dinning room table with the TV off. I was able to get reliable 4800bps comms at about 70ft. So im keeping me fingers crossed.
Post by: greengiant on June 30, 2004, 10:54:00 PM
2.5mm (pic)
3mm (crystal)
2mm (pcb)
So it will be approximatly 3mm+2mm = 5mm thickness
if thickness proves to be a problem, I may look at using a thinner pcb, but only if it doesnt reduce the quality of the board.
I truly dont think 5mm (or 0.197") will pose a problem in most installations.
As well the idea is to have the 5 wires for the SPI to run longest and then from the adapter to the LCD 10 wires have them be very short, thus reducing on total wire lenght needed. But the adapter doesnt have to go right behind the LCD, or that close to the LCD it can be hidden in the xbox compartments and the wire run to the lcd/xenium. You can even request custom lenght of the 5/10 wires for your installation.
Post by: moobar on June 30, 2004, 11:17:00 PM
Thanks for taking the time to measure. I dont think there any need to make it skinnier. I'll probably add some heat shrink to your final gadget so it doesnt accidentally short out somewhere so that'll add another 0.05", still plenty of room.
BTW, Do you have a name for your new gadget yet?
Also, do you have a thread following your new programmable XIR that I could follow? The new programmable XIR sounds like a great idea.
Post by: fff on June 30, 2004, 11:47:00 PM
If your "tool" could be a solution for a cheap LCD install and, why not, solderless, it would be great!
Parrallel LCD are cheaper and easier to find in France!
Post by: greengiant on July 01, 2004, 01:49:00 PM
The tape is sort of like duck tape, with the fine weaves of string in it and very sticky.
This will prevent any possible shorting on the backside.
Iam also trying a few types of paints and laquers, for a more proffesional look.
With this project SMT is the way to go. Not because of cost, since SMD crystals appear to be more expensive. But because of the location and possible installations that people will use it in. Most likely in the back of the LCD or in the back of the xenium.
As for the solderless, it will be to some extent.
Since the LCD connections are pretty standard, either 2x8 or 1x16 with the pins being the same. The adapter will come with a header to match the LCD. Female connector. If your lcd doesnt have the pins (ie is empty holes) then you can order a male pin header for a few cents more and solder it in place quite easily.
Also will look at possibly adapters for those lcds that dont already have a pin header, and you dont want to solder. Most likely a clip style.
I donot have a XIR dev thread, as that is more personal work, and recently I havent had time to work on it.

Sorry if this has been asked a thousand times, but how much do you think we will end up paying for the WHOLE THING (adaptor, LCD screen, etc...), and how do we go about mounting the LCD?
Post by: greengiant on July 05, 2004, 05:56:00 AM
Iam also working on a flat shipping, $4 anywhere.
the LCD itself, i dont know yet.
Locally i can get em around $20-30 CDN, but thats expensive.
Iam looking at a distributer who has em for about $6 for a 20x4 (for 100 at a time)
But im not focusing on the LCD right now, unless someone wants to shelve out an investement to buy a batch of 100 lcds.
Mounting, thats really upto you. I leave it hanging out side.
You can choose how much wire you want with it thought .
Post by: greengiant on July 05, 2004, 01:29:00 PM
The only limit to getting them from the distributer is I have to make an investment of over $600 + shipping and other, for 100 lcd's. And iam not sure if enought ppl will want. So far I have seen some 15 or so personal requests, and some dealer but not enought to allow me to fork out that much money. Remmeber i do this for hobby not business, so I dont have and cant invest much money into something that I dont know if it will pay for itself.
So for now, I say get one from ebay.
You can search for 'lcd 20x4' 'lcd 4x20' 'lcd 2x16' 'lcd 16x2' and a few other variations and you will find lcd's for under $10.
I saw one earlier I recommended for a friend that was $8+$3 shipping, for 4 2x16 lcds. Thats about $2 each.
I'm canadian, but for easy world wide integration, all prices are in USD.
But I can accept payment in other currencies.

Post by: greengiant on July 09, 2004, 05:00:00 PM
Also a splice connector for the 5v for the LCD.
An update on the prototype, I finally got a chance to test the adapter with XOS2.0 and have found something weird.
It appears the OS sends out the command so fast, even the 10mhz PIC cant keep up. But dont worry, the OS doesnt display anything important, what matters is XBMC and that works beautifully.
I have 8 Prototypes for sale, $13 each + shipping. They will be to get some money to fund the next set of productions ones. I will post more info soon. So you can decide if you want to buy one of them, dont expect much demand for the 8 i got, but just in case drop me an email if you want one of them.
Edit: Posted first pictures on website.
Post by: moobar on July 09, 2004, 06:09:00 PM
I dont plan to upgrade to 2.0 any time soon or even at all. OS1.1 does everything I need it to do, load a bios. Odd thing is I thought the CrystalFontz LCD could only handle 20khz clock rate, but then you of course have the delay of writing to the slow LCD.
I guess I can be a guinea pig for ya. Email sent.
Post by: greengiant on July 10, 2004, 04:02:00 AM
I dont expect to many upgrades once I get it super stable, but it is nice to have the easy ability to do so.
I wanted to point out that the because the OS doesnt display properly, doesnt mean the other apps wont. The reason is that every single app that will use the LCD has full control over the LCD (thus the OS doesnt matter for the app to be able to use the LCD). I have done extensive tests with XBMC and i havent been able to get the LCD to go out of synch, which is great.
The XOS2 synch problem, I found, but not exactly sure how to fix it. I have done some re-work of the code to optimize it even more, and now it shows 'Xenium OS 2.0' properly 99% of the time (the other 1% its on the upper left corner)
This is attributed to the LCD clearing the display, and the delay associated with this. IE, the XOS sends a clear command, the pic tells the LCD to clear and it takes a msec or two, but even thought it doesnt seem like much, by then the XOS has already sent one or two bytes which are then lost in the transmission and such the problem occurs. But as I said, i have managed to minimize this problem, and it does not affect functionality of the LCD in other programs.
I have spoken with a friend at Ozxodus, and will see if it will be possible for them to delay the output by 1msec (or fraction) which should not cause ANY problems or inconvinience to any user since these are times that are almost impossible to be noticed by the human eye.
Will also be posting a quick guide on how to install the prototype (for you lucky few) and hopefully more pictures.
I really got to thank all you out there. Lots of emails and questions have kept me going and finishing this project. I do it for you. So.... thanks for the support.
PS. Yeah I know this is a long post..but I wanna ask anyways.
If anyone out there has a contact, or makes PCB's, that can provide me the service please contact me. Iam looking for a possible cheaper manufacturer to try and lower the cost of the unit even further. Also 16f876a SOIC chips, if you can get em cheap let me know. Thanks.

didnt get around to testing the adapter on a 2x16/2x20 and just till now did i try and found something is broken. so im working to see what it is i have to do to fix it.
shouldnt be much different than that of a 4x??
there is always raw mode, and that works beautifully, no matter what. so will investigate more and let you all know.
Post by: greengiant on July 13, 2004, 01:56:00 AM
and after 1 pic blown, and some 5 hours, and some 1000 less hairs on my haid.
still nothing, its very strange, only happens with the 2x20 lcd.
it boots up, fine, displays the boot screen, then the xenium text, and it varies, but anywhere from right away to none the screen goes crazy.
I thought it may have been a crystal problem, but it works fine with the 4x20 so not sure.
I even tried removing all of the lcd code from the PIC, and it still happens. randomly.
any ideas greatly appreciated.
Post by: fff on July 13, 2004, 03:26:00 AM

Send me a list of all your parts and diagram (do not send code) and your spicifation so that I can send them to my contacts and will have them contact you with their bids
At lest you can make a little more money on your idea's and free's you up for other things.

spi2par is just working really fine.
Congrats greengiant!
PS : for the french speeking people, i've done a tut on LCD and Xenium,

Screen LCD on Xenium
This small guide will enable you to mount a screen LCD on your Xenium.
There are two means of assembling a LCD on Xenium. Either your LCD has comptatible connections SPI with Xenium (mainly the Crystalfontz screens) or you have a screen with connections parrallèle and in this case you will need an additional assembly.
I) Screen LCD SPI Crystalfontz.
It acts of the assembly simplest to also realize but most expensive.
The Crystalfontz screens compatible with Xenium are those of series 632 (16 characters out of 2 lines) and 634 (20 characters out of 4 lines). You will find them on page Internet of Crystalfontz in the section "serial LCDs".
The assembly is extrèmement simple, here the wiring diagram:
You thus need: to connect the wearing of entry of LCD GND to a mass of Xbox (for example a screw) and to connect the two ports +5V to a point +5V of Xbox (you have ports USB, the food of the hard disk, the connector of food. With each time, take the red wire (yellow = +12 V)). This will make it possible to supply the screen.
As regards connection to Xenium, there are two wire to weld: the DATA_in port must be connected to pine SPIOUT0 of Xenium and port SPI_CLK with pine SPI CLK of Xenium. Finally port SPI_CS must be connected to the mass.
In order to carry out these connections, two possibilities: either you weld wire between the LCD and the points indicated onto the diagram (fine wire, welding will not pose a problem if you take have weld the d0!), either you find the connectors which are well.
The connectors females which go with the port of Xenium are manufactured by company JST. The connector has the job number SHR-10V-S, the contacts have the job number SSH-003T-P0.2. Petite helps before you ruer in your store of electronics... you can require samples (samples) on Internet site of company JST. Do not ask 100 samples, that will make equivocal but 2 or 3, that passes very well!
If no methods is appropriate to you, get you to it cable provides in the Kit Xenium ICE with XorEase and locate the sons which interest you.
Once this cablé, light your Xbox and look at. Attention, Xos 1.1 will not post anything on the LCD (it do not deal with it). The XOS 2 goes on the other hand very well. The best test remains xbmc. Allez in the general options, part LCD and activate it. Look at the result.
IF any walk, very well, it does not remain any more which has position it.
II) Parallel screen LCD or noncompatible SPI
For those having a parallel screen LCD or with a connection SPI incompatible with Xenium, all is not lost. GreenGiant, member of the forum Xbox-Scene with designed a SPI2Par module allowing to pass from interface SPI series of Xenium to the parallel interface.
All is explained on its site. The module contains of with dimensions connections towards Xenium (with connector JST!!) and other of wire towards the parallel interface of the LCD.
Here a table recapitulating wiring has to carry out
Pine Name Connection
1 VSS Mass
2 VDD + 5V
3 VEE pine C of SPI2Par or to consult the datasheet screen
4 RS SPI2Par
5 R/W Mass
6 E
7 D0
8 D1
9 D2
10 D3
11 D4 SPI2Par
12 D5 SPI2Par
13 D6 SPI2Par
14 D7 SPI2Par
15 BGLED Optional (anode of the LED of rétroéclairage). See datasheet
16 BGLED Optional (cathode of the LED of rétroéclairage). See Datasheet
Here a photograph of the module and wiring on the corresponding LCD:
Once all that cabled test as in case 1) with xbmc.
And to conclude, a small photograph of a screen moving under XBMC!!

Awesome.. I can't wait! Hopefully, there will be a good way to mount an LCD on my Halo SE because I don't feel like doing any cutting to it.
Post by: greengiant on August 14, 2004, 09:01:00 PM
Generally, a paralell lcd thats 2x20 2x16 4x20 should work.
I havent been able to find out why my 2x16 doesnt work properly, so not sure, it has to do with the difference of power between 5v and 3.3v that the xen spits out. But no idea.
Ill try and put up a list of lcds as I get more feedback.

Heh, your kidding right?
My first install we be the usual 'dangling-out-the-side-double-sticked-to-face' then followed by a final install on the top right cover. I'll have to cut the rectangle by hand because the laser cutting shop I went to said they dont do plastics cause of some fumes or some other (wussies). The rectangle will be filled in with 1/16" plexiglass, I'll have to cut the metal under the cover of course, but it should provide a good final install. I dont need it on the face, the only time I'll be using it is when im on the move.

I know ive been pushing this back and back. Problems with attaining the PCB's.
They are now in the USA (as of the 8th) due to the weekend, theyr not getting shipped to me till next week. So hopefully by next week I should have them.
I wont be selling LCD's themselves (possibly in future, but not initially) some of the resellers will be packaging the spi2par with lcd's but that will be upto them.
As well, I will be having an LCD page where ppl can submit their LCD and results, as well as links to where you can buy lcd's.

Well I can finally say, im going to get the PCB in.
I got a hold of factory and it is confirmed, the PCB is in Canada (customs right now) It was sent out on Saturday from USA overnight. So I should have it tommorow.
Ill be begin taking orders, possibly tommorow or late this week.
Also posting some pictures, and install guides, so you guys can see exactly whats involved (not much) before you buy it.

Ive know about the lcd-con for a long time now. Its no threat to the SPI2Par because it tailors to a different market, the people who dont have a lcd enabled mod. But mind you the cost of it will most likely be close to the spi2par, so for those with a Xenium there is no real reason for it. Specially since with the lcd-con will probably need either new code added into xbmc, or it emulates the addresses used by the xen or smartxx.
Good luck to them on that.
As for the SPI2Par, GREAT news.
I got the PCB in today, they look VERY nice. Im assembling them, and testing to make sure the design is fully working. Tommorow I will get the PIC chips in to complete the rest of the batch.
Ill try and put up some pictures of the boards tonight.

Due to the cost of the PIC's i only built 8 of them. So im waiting for a few orders then I can finish the rest of the units.
So Im taking orders by email and then in a few days will have the site ready to take orders.
See the first pics,

GreenGiant,
Just a question. How tough would it be for an all-one-product for you. As in putting the products you already have together. Example, your lcd adapter, led extension for ice, and the xir, all into one product. I would be interested in such a solution, but dont know if it would be so cost effective unless there is more demand and its not that tough for you to adapt. Just a though.
EDIT: Any recommendations on an LCD or manufacture link to go to and exactly what kind it will support (#of lines and characters?)

As you pointed out it would depend on demand. Doesnt seem to be very much. Even tought Ive had the SPI2Par ready for sale now, for a few days, only a very few have emailed me to order.
I dont have a list yet of compatible lcd's, but generally a parallel LCD will work. Ill post soon a list.

etc... customers need more confidence...
i know i will certainly buy one if i can be positive it would be a wise investment..
does this have any issues besides the one not working lcd?
does the parellel LCD function and work the same as a SPI LCD?
any issues with XBMC or other lcd displaying applications?

True enought.
The way I implemented it supports almost all the commands that the CF SPI lcd implements, in order to be fully compatible with the XOS and XBMC.
When I say almost, its because some commands like scrolling, reverse and a few others arent part of the normal parallel lcd command set thus they need to be done in software and thus much more complications, but nicely all the apps that use the LCD (as per Xenium Libs) stick to the standard (basic) available lcd commands
Problems, out of 10 prototypes, and several finals. (Dealer units I havent received full feedback yet) havent reported any problems.
The outlook is good, so much so, that the good guys at Xodus were kind enought to make the XOS' LCD code actually more stable and compatible with the Spi2par by adding a few lcd command delays that donot inhibit the lcd, but allow seamless use of the lcd via the spi2par.
Id like to put up a list of the lcd's that work, but people just dont seem to send much feedback. So so far I only have 2 lcds on the list, the CF CFAH2004 series, and the http://www.electroni...a/dip204-4e.pdf very common among alot of xbox sites (was originally sold as SPI, but later found not to work with the Xeniums SPI ports)
Do note for this lcd (http://www.electronic-assembly.de/eng/pdf/doma/dip204-4e.pdf) the way the contrast is implemented, it cant be software controlled.
So yeah, my rep says it all.
Any other questions feel free to post or email.
