I'm trying to realize a radio DIY for my Cessna 172 cockpit.
I would like to use it for COM1/NAV1 frequencies. All is working ok with displaying the active and stbys freq, On/off switch, swap button and coaxial encoder.... Great!
As you can see in the picture I would like to use the switch near the encoder to select COM1 or NAV1 frequencies. Is it possible?
I'm in difficulty... which parameters I'd have to use, especially for this radio
swapping oparation linked to this toggle switch?
Also, if, possbile, to have the two leds working, one lights up for COM1 and the other for NAV1. Which is the parameter that lights up a led when COM1 is displayed, for example?...
The second stack will be the same.
Thanyou so much!
