Padauk Pfs154

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 you can change to a project directory and execute a "make" and a "make flash". Sorry that all comments are in german language, and sorry that this project works only in Linux (and not in Windows)
