M260 (send i2c) available?

Simme

Hi all,

I connected some PCF8574 to the i2c bus on my radds board in order to switch some additional hardware.

Now I wonder how I can send data to the PCF.

From all that I can see, the firmware supports twi, and even that specific chip is mentioned for keys.

But according to this overview, repetier does not support sending GCODE to I2C devices. 

What do I need to do to make it work?

Cheers,

Simme

Firmware interprets gcode, not your devices. You need to extend the firmware to use extra hardware. You may use implemented i2c function for communication, but there is nothing present except the fucntions already using it e.g. display driver using PCF8574.
