The controller uses a Arduino Nano board with a LCD display and several inputs and outputs connected to the manual control unit of the rotator. It essentially replaces the Yaesu GS-232 and implements a subset of its commands.
The implemented commands are sufficient for operation using rotctld. It
should work with most amateur radio related projects for Linux.
Connect the display and the control unit to the Microcontroller and set the
pins in config.h and lcd.h.
rotctl -m601 -s 9600 -r /dev/ttyUSB0
