ADF435x PIC

In CQ-TV253, I describe two PIC-based controllers for Chinese ADF435x boards. Here are the C sources and the Gerber files for the pcb.
File:source.zip contains four C source files:
- fatcontrol.c is the PIC12LF1552 controller offering a choice of 4 frequencies
- fat8sw.c is the PIC12LF1552 controller offering a choice of 8 frequencies
- thincontrol.c is the PIC12F629 controller offering a single frequency
- thin1552.c is the PIC12LF1552 controller offering a single frequency
Note that you cannot program a 12F629 on my 3v board; it needs 5v to progam but will run happily at 3v.
File:adf435x.zip contains the Gerber files for the V2 pcb. These are bundled to suit OSH Park's naming conventions but should also suit various Chinese fabricators.
