Hello,
I am working on a project that really requires that I send data over real serial. Not USB to serial but honest goodness real serial I/O pins.
It appears that there is a serial interface intended for uses with an LCD display. I would like to re purpose that.
If you know what to change to make it so I can send just regular good old fashioned gcode over this interface. No line numbers or checks sums. That would be really great.
