    Thanks for the code. I am using a 16×2 LCD, must I include all this libraries (#include “SPI.h” #include “Adafruit_GFX.h” #include “Adafruit_ILI9340.h” #define _sclk 13 #define _miso 12 #define _mosi 11 #define _cs 10 #define _rst 9 #define _dc 8)

    OR can I just use #include ?

      OR can I just use #include “LiquidCrystal.h”?

    Hi,
    your code (or explenation on how to use it) is incomplete. You provide two ino files, wich one to compile? one does not run wihtout the other and the interrupts.ino is giving errors on compile (undeclared variables and sei())

    Is this code functional or just a sample?

    Thank you very much, great initiative, too bad its not complete 🙁
