MPR121 breakout board LED

by mohawkpiper on Sun Aug 23, 2020 2:38 pm

Is there a way to turn off the LED on the breakout board through code? (Aside from removing or covering the LED.)

I can't seem to find any info on it on the internet.

Thanks!

The LED is driven by the MPR121's IRQ pin:

I'm not sure there is a way to disable the IRQ output on the MPR121.
