Step 3: Program the Micro
The next step is to program the Microcontroller.
Just use whatever PIC programmer you use.
The Hex file is attached! Remember to use either the 50Hz or the 60Hz firmware depending on your region.
I have also added support to keep the clock running on battery backup when power is lost.
[Update] - I have updated the 50Hz and 60Hz firmware files - there was a simple coding error that affected the accuracy of the clock.
