Hi Dave,

Thanks for sharing your code.
The only thing that's not clear to me how do you have the PS3,PS2,PS1,PS1 jumper on the back of the board.

Hello,

See post number 9 in this thread. Dave's program uses the 8bit mode. Solder jumpers PS2
and PS3, remove solder from PS0 and PS1.

I received my display Monday. It came with PS0, PS2 and PS3 soldered, which is the 16bit mode.

With out a data sheet its a bit confusing at first. Unsoldered = 1 and soldered = 0, its because they use pull-up resistors.

Here it goes. This is the datasheet for the SSD2119 controller, which is what this display uses. The right PS combination is on page 28.

Thanks Robert,

I have the controller data sheet, I ment data for the development board. It does not come with any schematics or info. But the pcb is clearly silk screened. It has a lot of features for the money. DC to DC converter for vlcd, touch screen controller, SD card socket, pads for eeprom expansion. The best part, is you don't have to deal with the 0.5mm FFC cable connections.

@Dave,

Have not fired it up yet, need to change my pcb to 3.3v. Will report back when I get it
going with an interesting app.

Thanks

You can get the schematic and other data here http://cgi.ebay.com/3-5-TFT-LCD-Modu...ts_Supplies_ET

Scroll down to the "Download"

If you have any trouble finding it let me know and I will send it to you.

Dave,

Thanks for the info! That guy is selling them for almost double. I ordered a second one for $35 in case that seller raises his prices or runs out. You can't build this for under a $100 in small quantities. Display $54 (Crystalfontz), PCBs $59 (expressPCB), chips, connectors etc. Unreal!

Also be sure you make the chip select for the touch screen controller high. If you leave it floating the SD card reader may not work (hard lesson learned ;-)

If you guys make something cool be sure to show us.

Take care

Dave
