Web29 okt. 2024 · Each timer is essentially a counter with programmable clock input. At each clock period, the counter increments by 1. You can find timers' input clock speed on the Clock Configuration tab. In this case we see that the APB1 Timer Clock is … WebThe reason: I was calling the HAL_TIM_ReadCapturedValue(htim, TIM_CHANNEL_1 ) function from ISR. Replacing this call by htim->Instance->CCR1 inside the ISR solved my problem and data in the array is now correct and the mean and median functions can process correct data and give correct float results.

I use here a DMA (triggered with a timer)---->PWM (timer) to create a neopixel LED driver, maybe you can fish something out, specially the DMA+PWMtest. The mcu shouldnt matter as long as you have DMA and TIM available to use. high country mt

WebYou will have to manually update the appropriate CCRx register (x is the PWM channel you're using, which is CCR1 in your case). The ARR register is the the register you will reference when calculating the new value for the CCR … Webstm32的PWM占空比. PWM一共有两种模式,PWM1模式:CNTCRRx为无效电平。. PWM2模式相反。. 有限电平通过设置极性来确定:. TIM_OCInitStructure.TIM_OCPolarity = TIM_OCPolarity_High;表示有效电平是高电平。. 设置初始PWM占空比:.
