I have recently bought a CTE 5" TFT with touch screen and Font IC. I got most of it working fine but I have 2 problems at the moment.
The display is making Mega 2560 very hot while if used with Due it behaves normally. Though searching in this forum and internet I got some hunch that the 3.3V backlight might be drawing too much current and stressing out the Arduino mega's 3.3V regulator/PWM generators. There is a jumper/SMD register spot marked as R9 which may activate the SSD1963 internal 3.3V PWM generator and migh reduce the stress on Arduino.. But I dont know what value Registors to put there or just solder them on.. could not find any documentation on this.. Any lead will be appreciated...
Image quality when used with Mega is very very bad.. its like 8bit image quality.. while on Due its quite good. Is that a hardware limitation or anything can be modified in the sketch/Library to fix this?
