  • How to use 2.4 inch TFT LCD SPFD5408 with Arduino Uno and Mega

    Thank you very much for the guide and library!I got one and tried your library with Arduino Mega, first it didn't work, after some cross-referencing it's working, had to change pin definitions (yup, one more pin-out to try) In the back the shield says:"KeDei 2.4 Inch TFTLCD version 1.0 2016/2/1"#define YP A1 // must be an analog pin, use "An" notation!#define XM A2 // must be an analog pin, use "An" notation!#define YM 5 // can be a digital pin#define XP 6 // can be a digital pin
