Hello! It took a while to dig out a v1.3 board to test on, but I ran it ok with the standard polargraph_server_polarshield firmware.

There are a couple of different driver chips used in those screens though. The ones I have labelled “V2.1” are newer and need

#define LCD_TYPE TFT01_24_8

whereas the ones labelled “V1.2” are a bit older and need

#define LCD_TYPE ITDB24E_8

Only other thing that might need setting is the calibration string:

// for the 2.4in screen that is current.
#define CAL_X 0x03C34136UL
#define CAL_Y 0x03C0018AUL
#define CAL_S 0x000EF13FUL

which should be a file called UTouchCD.h in libraries/UTouch.

good luck!

Hello from France !
Yesterday, in our fablab here (http://www.labfab.fr) came a man with a polarshield V1.3 who broke the 2.2” lcd screen of his polargraph. He came with a new 2.4” screen bought after august 2014 and didn’t know anything about arduino.
I came to your great website, dowloaded the github package, installed the libraries, complied successfully with arduino IDE, uncommented the good lines in the .ino file and uploaded the code in the arduinomega. No problem.
The screen lights up but stays white…
Please can you help us ? Any advice ?

P.S.Congrats for this great project. I made a DIY variation of a polar drawer with two steppers last year and i love polar bots (especially delta printers:).

Looks like you’ve downloaded the webpage that has the code on it rather than the code itself. If you’re at http://code.google.com/p/polargraph/source/browse/#svn%2Fembedded%2Ftrunk%2Fpolargraph_server_a1 then you need to click on each file in turn and then choose “view raw file”.

Good luck!

I have been trying to upload the firmware to my arduino for an hour now and having the same problem. Attached are my error I receive

Any ideas?
