Folders
original
Contains the source (.asm) and compiled (.hex) files for the older GPSDO design that did not have an inverter between the PWM output of the PIC16F1455 and the filter that supplies the control voltage to the oscillator.
inverted
The files for the newer design that has FET transistors supplying the control voltage. The FETs invert the PWM signal, so a small change is needed to cater for this.
