# dspic33ck-power-isolated-voltage-acquisition-board v1.0.1

### Release Highlights

1.0.1
Git LFS no longer used to track mc3 files

1.0.0
This firmware controls the dsPIC33CK on the Isolated Voltage Acquisition Board.
It facilitates isolated measurement of up to 3 voltages.
Upon receipt of a trigger on pin 3 of header J4, the dsPIC33CK will digitize the voltages on L1, L2 and L3 with respect to N with its on-board 12-bit ADC.
The 3 measurements, along with a checksum, are transmitted across the 4kV isolation barrier via optocouplers.

2-wire SPI is used for transmisson
* SPI clock on pin 5 of J4
* SPI data on pin 4 of J4
