Easy PDK programmer for PADAUK microcontroller

A proof-of-concept (hack) to implement neural network inference on a very tiny 8-bit microcontroller.

An Arduino based programmer for PFS154. Programmer is realised with external switching regulator and OP-Amp LM358 (like Easy-PDK-Programmer). For now, the progammer can only flash the PFS154. I'm analyzing programming sequence for PFS173 but for the moment I have no idea to realise it. Perhaps in the future. A complete toolchain is include so yo…
