af9b2b1ce4 Fake 10-bit mode, using random number lookup for low bits. 
Untested.  Need to test 16-bit mode (current compilation) first
then go back to 10-bit.

b4375aeab2 Tweak some build options, add -O1 
Make PC output send 0x8000 if there was ever an ADC overflow or underflow.
(The ADC underflow check might be more strict than necessary).

8977dea014 Include .lst files in output 
Add dac_to_current scaling so we can set limits easily.
Change interrupt to do everything in terms of current.  Much simpler to understand, and is preferable if we can get away with using the cycles.

b95491274d Set up 128 KHz 12-bit ADC sampling with DMA, and send to UART at 0.5 Mbps. 
Seems to work well.
Next step is to process ADC data at 128 KHz to determine DAC stepping,
and send DAC + ADC to PC at 8 KHz.
