Suggestion: Add external switch for toggling digipeater function

[hazyhq]

Hello Piotr. A suggestion for your next VP-DIGI firmware revision. Would you be able to add an input on one of the GPIO lines to control the digipeater function? It would be very convenient to be able to quickly enable/disable a fill-in digipeater role by way of a button when the VP-DIGI is mounted in a vehicle and a nearby operator is mobile on foot with an APRS tracker. Adding an optional LED output to confirm the digipeater state would also be useful, Best regards - Allan de ZL4MD

Thank you for the suggestion, added in version 2.1.0. Disable switch is at PB0, which is pulled up internally. The digipeater is switched off on PB0 pulled to GND. The PB1 is set to high when the digipeater is active. The digipeater is active only if it's enabled in the configuration and PB0 is not pulled to GND.

Thank you very much for implementing that feature so quickly! I look forward to building it into yet another digipeater using your excellent design. The APRS global community appreciates your extensive programming skills! Best regards Allan
