How to activate all RGB Leds on KL82z

us1 — Thu, 03 Nov 2016 13:52:53 GMT

Hello,

does someone have a code for the activation of all RGB Leds on the Kl82z?

I'm trying to get it working, but the example only gets the red one working. And the libs are not that I can understand what to do to get the other two working.

Hi Ulrich,

Please add "LED PIN_MUX Configuration" code for other two LED pins.

Best Regards,

Robin
