Programmatic access to LED's

n8wrl Member ✭✭

I am programming against my FlexControl for fun, and I've figured out the serial text I get back from it when the knob turns, buttons pressed, etc.

I cannot figure out what command to send to turn the LED's on and off. Can anyone point me to a reference? Unable to find so far...

Thanks and 73!

    I think that I understand your question

    Pushing on the AUX buttons activates the programed function and appropriate LED. Rotating the knob adjusts the enabled function. The tuning knob also has a switch associated with it. Push straight in on the tuning knob to cancel the AUX-1 through 3 functions and LEDs. The knob now changes the radio's frequency.

    Yes, that's when SmartSDR is connected to the control. When you press a button, SmartSDR "does the thing" you configured the button to be, but it also sends a command to the flexControl to turn on the LED. The control does not turn on its LED's by itself.

    I am writing code that talks to the FlexControl to do other things, and I need to know what that "turn the LED on" command is that SmartSDR is sending to the FlexControl.
