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
