a simple, 1bit synthesizer written for PIC16FXXX in C. compiled using SDCC.
unfortunately, cpu speed is limited to 20MHz on PIC16F627A(which is the MCU i am using) and polyphony is not usable yet. maybe it will be available in future.
clone repo, install sdcc and gputils and type:
$ make compile
install picprog and:
$ make program # or just make
install gpsim:
$ make simulate
