I am trying to turn on the user leds on the stm32wb55 nucleo board. What am I doing wrong?

[sugarkoatedlies]

step 1: initialize clock

step 2: set pins to output

step 3: set corresponding 'set' bits to 1 in BSRR register

int main(){

//enable clock for necessary ports

//clock for leds: port port B, pins 0, 1, 5

RCC->AHB2ENR |= RCC_AHB2ENR_GPIOBEN;

//RCC->AHB2ENR |= RCC_AHB2ENR_GPIOCEN;

//decide which pin in input or output

GPIOB->MODER |= GPIO_MODER_MODE0_0;

GPIOB->MODER |= GPIO_MODER_MODE1_0;

GPIOB->MODER |= GPIO_MODER_MODE5_0;

GPIOB->BSRR |= GPIO_BSRR_BS0;

GPIOB->BSRR |= GPIO_BSRR_BS1;

GPIOB->BSRR |= GPIO_BSRR_BS5;

};

Perhaps you could use a debugger, and inspect the registers?

You only need to write BSRR, no need to RMW

If you want to use RMW access ODR

Avoid exiting main()

What do you mean RMW? Are you saying I dont have to enable the clocks for gpio B?
