R-Pi as Arduino HDMI server

Posted on Thursday, January 3rd, 2013 in Arduino, code, R-Pi by the machinegeek


jokkebk over at Code and Life has developed a simple “HDMI server” for the Raspberry Pi that uses pyserial to receive commands over Pi’s serial interface, and pygame to display graphics primitives according to those commands. An Arduino client was written to send these commands to the Pi, drawing a string of blue rectangles to the screen.

The boards are interfaced using a simple level shifter to handle the difference between the Pi’s 3.3 volt and Arduino 5.0 volt levels.

Via Code and Life.
