I want to see if it is possible to use an atmega32u4 as a keyboard interface for some CNC mills to jog the mill etc.
The mills are controlled by a PC through parallel or usb depending on the model. The keyboard needs to work through USB.The teensy looks nice pretty much what I was after but I want to make it my self though. That will allow me to hook a few other features on to the same board i.e. the emergency stop button which goes into the motor controller board.
