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.

7df0122961 Bugfixes & updates. 
I think the 12-bit ADC can't drive the optoisolator, crap.

c495a51866 Update for latest circuit changes 
Now needs a smarter algorithm for figuring out the DAC from the ADC.

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.

458c1e9ed1 ADC seems to work now. 
Added adc_convert to give us a nice signed 32 bit value as the result.
