My current set up is running Volumio 1.51 on a RasPi B+. I have a HiFiBerry Digi + board for SPDIF out to my DAC. I’ve also managed to get I2S to the DAC working too.
I’ve also got an Arduino Mega with a Ethernet shield, this connects to Volumio/MPD over the network to get current track information and displays the info on a 20x4 LCD, this will soon be updated to Touch TFT screen. I’ve also got an old Apple Remote with a IR receiver working on the Arduino too. Eventually I want to get the Arduino/Apple Remote and Touch screen to control Volumio/MPD, play, pause, forward, etc but I’m not sure of the best way to go about this.
The reason for using the Arduino is the greater flexibility for adding control options and I want to try to keep all control processing away from the Pi. The other reason is my limited knowledge of Linux/Python scripting.
Any thoughts on using the Arduino to control Volumio/MPD? Is it even possible without programming on the RasPi?
