Hi Friend ,
I have received my 3.95" touch screen , but i have problem with touch . ( This screen )
I tried use mcufriend diagnose touch :
Making all control and bus pins INPUT_PULLUP 15:03:37.930 -> Typical 30k Analog pullup with corresponding pin would read low when digital is written LOW 15:03:38.034 -> e.g. reads ~25 for 300R X direction 15:03:38.068 -> e.g. reads ~30 for 500R Y direction 15:03:38.103 ->
Diagnose tft support : ( screen work with mcufriend_special modified )
Diagnose whether this controller is supported 15:04:46.960 -> There are FAQs in extras/mcufriend_how_to.txt 15:04:46.994 -> tft.readID() finds: ID = 0xD3D3 15:04:47.062 -> 15:04:47.062 -> MCUFRIEND_kbv version: 2.9.8 15:04:47.096 -> 15:04:47.096 -> Probably a write-only Mega2560 Shield 15:04:47.130 -> Try to force ID = 0x9481
Any idea about touch problem ?
Edit : screen not work with UTFT library
Thanks good week end .
