VMAC PiHat v2 LED Test
The HAMKit VMAC PiHat includes four on-board LEDs, to facilitate testing and use:
- Green : 3v3 Supply
- Blue : Status on GPIO 22
- Amber : User or RTS on GPIO 17
- Red : PTT on GPIO 27
All of our sample and test code is developed in Python.

# Initialise three LEDs to flash
# Green = 3v3 Supply Healthy
# Blue = Status - GPIO 22
