Hello everyone,

My hardware:
M0+4x4Foilkeyboar+I2C (PCF8574 on I2C) and then add the TFT ST773 on SPI.

The moment i include this library for my ST7735 the compilation fails :-(
https://github.com/sumotoy/TFT_ST7735/tree/1.0p1

Can any one help me to change the "IDLE redeclaration" for both librarys to work together on my M0?

From the keypad I2C Library i only use the upper Keypad_I2C for the pcf8574


Okay i changed in the Keypad.cpp the IDLE to IDLE_KEY now it collides less with this library..
