Hal_tim_ic_start_it
WebOct 30, 2024 · The above callback function is called whenever the rising edge is detected. When called first time, Is_First_Captured was 0 so the hence the IC_Val1 will be recorded. When called in the second rising edge, the Is_First_Captured is 1 now so IC_Val2 will be recorded and you can see the rest. Frequency is equal to the (TIMx clock / Difference). Web我将 tim2 的通道 1 作为输入捕获测试通道，stm32cubemx 会默认配置 pa0 作为输入捕获的 io 口（pa0 有该复用功能，且不需要重映像，所以自动将 pa0 设为 tim_ch1 的 gpio），定时器的参数设定如下图所示（输入捕获的配置可以不用改，默认捕获上升沿）：

WebJul 21, 2024 · Now you can start DMA to GPIO transfer by calling MY_TIM_IC_Start_DMA (&htim2, TIM_CHANNEL_1, (uint32_t*)gpioBuffer,GPIO_BUFFER_SIZE); Actual transfer must be triggered by providing pulses on TIM2_CH1 input pin (for example, by using output compare pin from other timer channel). Those pulses originally was used to save Timer2 … WebMultiple channels input capture at the same time. Hello, I'd like to know if there is possibility to use all input capture channels at the same time? For starting timer i use function wich enable only 1 channel: HAL_TIM_IC_Start_DMA (&htim1, TIM_CHANNEL_1, &restWave [0], 1); I'd like to use something like this (but obviously it doesn't work)
