I have very little up and running. Mostly concept testing. I write embedded software for a living so this has been fun so far. I've been waffling between class libraries for ease of maintenance and code sharing and much more low level for speed. It may end up using a hybrid of both. I have managed to read the amp and control the tv over serial from my mac. This week I want the Arduino itself to do that.
► XMC-1 ► L+R: XPA-1L driving Polk Audio RTI-A9s ► Surrounds: HK AVR-635 driving a pair of Mission M7dS bipoles ► Centre: Emotive C2 driven by two XPA-1L (bi-amped) ► Subs: Velodyne CHT-12 ▷Twin Energy E:XL-S8 ► Sources: ▷Sony PS3 Slim ▷Mac Mini with Bitperfect ▷Apple TV Gen3 ▷Roku ► Other: ▷Yamaha RX-V750 ▷Paradigm 7SE MK 1 ▷PSB 300 ▷PSB 500 ———————————————————————————— ► In the works - Arduino Trigger Controller (eventually) ————————————————————————————
I cannot find any documentation on the trigger voltage, and current... in, nor out. Anyone able to help? The out would be from my XMC-1, and the in would be to my XPA-1Ls
For Chuck's circuit he used a Zener diode to bring to 12v trigger from the XMC down to 5v for the trigger input signal to the Arduino Uno. 12v works as trigger inputs to the amplifiers which is taken from the 12v supply to the Uno and fed to the relays.
