How to connect a Quadro Jumbo to Pi2Jamma for auto monitor rotation with pinHP image.
Requirements: A 5 V DC single channel relay.
How it works: Quadro's monitor rotation is set by a simple hardware ON/OFF switch on the control board. As long as the switch is OFF, the monitor is kept in horizontal position or turned there, and vice versa. The switching is now taken over by a relay, controlled from pinHP image via GPIO-26.
