hello folks i am trying to output on a of my nucleo F44RE board i am using STM32CUBE and ewarm problem is when i connect a scope to the pin i dont detect anything would anyone know why this is my code i am trying to toogle pin pc12

thanks

I don't use Cube, but this is suspicious:

/*Configure GPIO pin Output Level */

HAL_GPIO_WritePin(GPIOC, GPIO_PIN_10, GPIO_PIN_RESET);

/*Configure GPIO pin : PC10 */

GPIO_InitStruct.Pin = GPIO_PIN_10;

and then

HAL_GPIO_TogglePin(GPIOC,GPIO_PIN_12);
