Hi, i'm implementing a PWM signal using STM32, the problem i'm facing is that when i set the duty cycle of the pulse to zero... i get the pin to stay high, even if i disable the timer associated with the PWM output.This are my setting:My APB2 Bus is ...

Hello,I implemented a simple spi transmission on a STM32F469 based board.The problem i'm facing is that the spi function I'm not getting any value in the receive buffer.Trough the oscilloscope i can see the byte being send and the one transmitted bac...

Hello,I'm trying to do a calibration of the ADC before starting it, but in comping i get this error.I declared all the hal libraries related to the adc.Thanks

I'd like to get ADC readings, implemented with DMA while running in an RTOS.The problem is that the ADC with DMA interrupts the RTOS... don't know what could be the cause maybe interrupts conflicting?

HAL_TIM_PWM_Stop (&htim5, TIM_CHANNEL_3);when the CCR3 value is zero ( the duty is zero)

I cant use the classic HAL_GPIO_WritePin(LOOP_EN_micro_GPIO_Port,LOOP_EN_micro_Pin , GPIO_PIN_RESET) right?LOOP_EN_micro is the label i gave to the TIM5_CH3 in the IOC configurator. or do i have to initialize the pin to gpio and then re initialize a...

So you suggest to stop the timer and reset the state of the gpio pin, right?Thanks for the insights.

Riccardo Franceschetto · 2024-10-17

Thanks, but why the pin stays high even if the timer is stopped?

Hi, i'm having trouble with PWM at duty cicle 0... the signal stays high like the duty is at 100%... could this be similar to your case? how do you manually set the pin at zero?
