The MCUs - Holtek BS82C16A-3 and BS84B08A-3 - natively support #SPI and #I2C, but this isn't either of those.
Each #frame with one byte of data starts with a long (~10ms) low pulse (for #sync, presumably), followed by the #data line returning high for ~5ms, then the data bits are transmitted as low #pulses of different durations for 0 and 1 - 0.6ms and 2.8ms.
The eight data bits are followed by a stop/end bit, always short.

For whatever reason, it was trying to display N-1 blanks and a "0" as the first digit when fed with valid #SPI input. After several evenings of debugging, I realized that I had the SDI wire hooked up to the wrong pin on the #AVR. *facepalm* Moving the wire to the correct place made everything work. #electronics

I'm reading the FM input via #micropython. That inner loop is reading at no more than few hundred Hz, so I can't modulate with more than a couple hundred Hz. Just proved this by turning the modulation freq until I heard it aliasing. 350Hz
I'm controlling the #ad9833 via #spi, so there's no good #analog way to do the FM.
I already have the jack and knob wired in, tho. What else can I use it for?
