Dear folks,
I am considering getting a LCD Graphics unit (DEV_DISPLAY_128X64) but was wondering if anyone has ever attempted to use it with an I2C I/O port expander like the MCP23017?
It would be an interesting challenge to figure this out, but before I proceed, can you think of any issues that might get in the way?
I am a big fan of the Teensy 2.0 and 3.0, and I would like to make this work in order to free up I/O pins for other tasks.
Many thanks!
