Is there a way to set timer CH1 pin (PA5) to LOW from code?

I have configured TIM2 to set CH1 to Force Active if x Pulses are reached. That's working fine.

Is there are a way to set it to LOW again from code (main loop)?

This seems not to work:

HAL_GPIO_WritePin(GPIOA, GPIO_PIN_5, GPIO_PIN_RESET);

Lopp in the reference manual for foirced output mode.

Thanks for your answer! This one? https://www.st.com/resource/en/datasheet/stm32g431kb.pdf

Can you point me to the page please? I can't find it.

Ah, I got it: https://www.st.com/resource/en/application_note/dm00042534-stm32-crossseries-timer-overview-stmicroelectronics.pdf

chapter 2.4

but

TIM2->CCR1 = 0;

seems not to set it to low. Do I miss something?

If nothing elpse help, consider also to switch to and back toGPIO alternate function to output with the right ODR value.

Nice, that's helpful. Thanks a lot!​
