Hello all
I bought a  Powertip PG320240WRFHE9 with touch on ebay and I'm tryng to use the S1D13700 Library.
I found this info here http://www.cafelogic.com/download/s1d13700_arduino_documentation/
It is a great display for arduino projects but I had a problem put it working on arduino.
I follow the wiring shematics but it just turns on the back light and noting on it.
the arduino is running a demo sketch.
Does anyone is working with this beauty display for change some info of wiring and sketchs
I attach the library and a example that Im using

I have the same problem...
This might be a solution: http://arduino.cc/forum/index.php?topic=51432.0
I will try it tonight.

In the mean time I had to use the the breadboard for another project. When I wired the display again, it worked...
I used exactly the same schematic from the cafelogic website...
Don't ask me why, but now it works!

Hello dude.We are bad luck:) the same thing append to me.Last week I wired it again and it worked.I already be able to seend new bitmaps to it.and now I working on the touch function.I want to make menus and then respond to the touch position.

Yep!

I'm pleased to see there is more users of this nice LCD.
I had the same problem with the original schematic from cafelogic. I was been able to get it work without connecting one pin. But i don't remember which one (Vcc BL-A, RST or DOFF). I will make a try soon.

In fact, i would like to know if someone succeed to incorporate huge characters to S1D13700 and how ???

PS : I see the file of Hugo007 with a new font. I will try some work on it. At cafelogic, there are some new tips too. I didn't work with this LCD till 6 months that's why i'm late !!!

Hi all!

I also bought one LCD from cafelogic some months ago and I'm starting to test it now. It would be great if anyone has any working code for a simple menu or any advice about how to do it the best way... Do you generate the graphics? or do you load them from a bitmap image? how do you store them? in a SD card? how good/bad is the refresh rate? the demo code seems a bit slow...

I'm using a custom board with an Atmega644PV@8MHz and a Sanguino bootloader, it should be fully compatible with any arduino code... Anyway, I would like to change the board to an Atmega644P@20MHz and correct some mistakes I made. You will see that I changed the ribbon cable to a longer one, the stock one wouldn't let me mount the LCD on a panel the way I want. I still have to populate the touch sensing chip, I used the AR1020 as it's recommended in cafelogic and I don't have any free analog input in my design.


(the green wires are there because I ruined the vias of the LCD connector when I soldered it backwards and had to drill them to clean the solder)

The schematic of cafelogic is right, the only problems I had with this LCD were my fault.

It seems that cafelogic doesn't shell this LCD anymore... do you know any other place to buy it?

Thanks
