Problems Using EEPROM Registers

[Tango_XXVI]

Hi, 

I have working with an interfase using the Gameduino, I don´t have any problem until I use the EEPROM registers, the touching interaction became crazy, to fixit I use the selfcalibrate comand, works but not at 100%, how can i really fix it, witch register are better to not use, i think that is the problem, i'm using some same ragisters that is required for the well function of the screen.

Please help me!

Right, the GD2 stores calibration data in the first 25 bytes of Arduino EEPROM.

So to avoid clobbering it, I suggest using EEPROM addresses 25 and upwards.

Thanks, but i used addresses 70 and upwards, and start to became crazy anyway...
there is a quick mapping of my arduino EEPROM register, maybe you can tell me whats wrong... I'm using an Arduino Mega, and mapped before and after the self_calibrate
Address - Value Before - Value After
000 - 124 - 124
001 - 80 - 122
002 - 1 - 22
003 - 255 - 55
004 - 255 - 255
005 - 69 - 248
006 - 255 - 254
007 - 255 - 255
008 - 255 - 255

054 - 80 - 80
055 - 1 - 2
056/4k - 255 - 255

I know it can change a lot between devices, but maybe you can help me to know whats bugging my proyect.

Thanks!
