The specs of this project are:

I'm prototyping with one of Microchip's Curiosity dev board, which comes with a 20 pin DIP PIC16F1619.

I've gotten to blinky with MP Lab X and the code configurator, the documentation isn't that great, but maybe just because there's a lot of it. Getting to blinky took 2 hours.

I swapped the 20 pin DIP out for a 14 pin DIP PIC16LF1703. This chip has 2 on-chip opAmps. I need a constant current supply for the circuit I'm designing, and so thought it might work with one of the on-chip opAmps.
