Description
- make channel count and sampling rate of ADC independent from DAC
- allow to do ADC only or DAC only
- allow to select digital I/O Fs: 22.05, 44.1, 88.2
- directly drive multiplexer (maybe using pins at the top of P8), leaving the 16 digital I/O available and not requiring ARM to write the binary counter.

- add option to disable GPIO
- do float conversion in the PRU. This currently eats up to 8% of CPU time. Alternatively, do it with NEON on ARM.
