So, I mistakenly wired my PCB to pin 30 (GPIO3) to use as a power led indicator (active low).
Unfortunately, I realized with the PCB in hand that GPIO3 is not in the list of available pins to control through PANS.
What I find surprising is, GPIO2 and GPIO3 in the DWM1001-DEV schematics are wired to 2 leds…
So, a few questions:
- can I toggle GPIO3 manually? (
dwm_gpio_cfg_output(3,0)didn’t seem to work)
- can I somehow lower it if not using the UART feature?
- why is GPIO2 controllable through the API, but GPIO3 is not?
- why even list GPIO3 on the DWM1001 schematics if it’s not intended to be used?
