Hi All,
I am using 'NRF SDK v2.7 + NRF5340 DK + VSCode' and cloned a official nrf 'matter light bulb' sample.
My question is the default 'matter light bulb' uses NRF5340 onboard LED1[p0.28] as various status and LED2[P0.29] as Light-Bulb[ON,OFF and Dimmable via PWM].
But I don't want to use this LED1 because I have to use it for some other purpose and want to map it to LED3[p0.30]. How can I free this LED1 as I cant find anywhere in code where I can make the changes.
Any idea how to:
- [1] Modify the overlay
- [2] Make the code changes
- [3] I cant find in code on how LED1 is being controlled in the light-bulb sample. Pardon me maybe I could be missing out
Please see my default nrf5340dk_nrf5340_cpuapp.overlay
