Hi Folks
I'd love to "feed" the digital audio signal from a YAMAHA YMF-262 (OPL-3) FM chip directly into Teensy so I can play with it in the digital domain before pushing out of the audio shield.
According to the data sheet the sound data is a 16-bit offset binary data stream with 3 timing signals illustrated in the picture below (page 5 of the data sheet linked here)
I’m hoping this can be achieved by hacking one of the audio library input objects... Perhaps the AudioinputI2Slave? I’m guessing the 49.7kHz sampling frequency of the FM chip might be a problem?
Would love to know if you think this is at all possible and perhaps some tips to get me started on the adventure?
Thanks!
