I have this project where I have managed to build and flash my code onto the controller. I copied the example code from blinky (that didn't work) to my main.c and then I changed some pins, still didn't work. So what I tried was that I searched up and came across nrf_bpio_cfg_output and nrf_gpio_pin_set/clear in order to set and clear my pins. The problem still persists, I don't know if has something to do with setting the wrong output pin or something, I really don't know. Even tried multiple pins.
I want the output to be on pin 7, or pin name P0.03. On my nRF51802 chip mounted on a custom board.
I'm using "nRF51 SDK v10.0.0" and gcc compiler, therefore without IDE.
