Feature Request: Assert KX3 ACC2 GPIO line on tune

[Bruce Nourish]

Hi folks,

I'm building an Arduino-based mag-loop autotuner, and I have a feature
request for better integration with the KX3. Would it be possible to create
a new mode for the ACC2 GPIO line, to go high when the radio is in
transmitting a carrier in response to a user pushing TUNE, and low at all
other times (specifically including when the user pushes ATU tune)? I'm
open to more sophisticated or bidirectional communication on that line too,
but this seems like an easy place to start.

I don't have a K3, and I don't know which ACC line would be most suitable
for that radio, but if this is a good idea for the KX3, please consider a
similar request for this feature on that radio.

Thanks!

Bruce

I would also be keen to see this feature implemented, with the ability to invoke TUNE with either High OR Low (selectable).

I would like to use an LDG Z100-Plus with the KX3, and have the radio automatically enter TUNE when the Tune button on the Z100-Plus is pressed. I believe that the Z100-Plus pulls low on Tune?

Without this feature, the user must invoke TUNE on the KX3, THEN activate the Z100-Plus, THEN turn the carrier off once tuning is complete.

To invoke KX3 TUNE on GPIO Low, and cease KX3 TUNE on GPIO High would solve this problem. I would be grateful for your thoughts on feasibility and would be happy to run a beta firmware.

Kind Regards
