Detailed Description
Input Capture management functions.
=============================================================================== Input Capture management functions =============================================================================== =================================================================== TIM Driver: how to use it in Input Capture Mode =================================================================== To use the Timer in Input Capture mode, the following steps are mandatory: 1. Enable TIM clock using RCC_APBxPeriphClockCmd(RCC_APBxPeriph_TIMx, ENABLE) function 2. Configure the TIM pins by configuring the corresponding GPIO pins 2. Configure the Time base unit as described in the first part of this driver, if needed, else the Timer will run with the default configuration: - Autoreload value = 0xFFFF - Prescaler value = 0x0000 - Counter mode = Up counting - Clock Division = TIM_CKD_DIV1 3. Fill the TIM_ICInitStruct with the desired parameters including: - TIM Channel: TIM_Channel - TIM Input Capture polarity: TIM_ICPolarity - TIM Input Capture selection: TIM_ICSelection - TIM Input Capture Prescaler: TIM_ICPrescaler - TIM Input CApture filter value: TIM_ICFilter 4. Call TIM_ICInit(TIMx, &TIM_ICInitStruct) to configure the desired channel with the corresponding configuration and to measure only frequency or duty cycle of the input signal, or, Call TIM_PWMIConfig(TIMx, &TIM_ICInitStruct) to configure the desired channels with the corresponding configuration and to measure the frequency and the duty cycle of the input signal 5. Enable the NVIC or the DMA to read the measured frequency. 6. Enable the corresponding interrupt (or DMA request) to read the Captured value, using the function TIM_ITConfig(TIMx, TIM_IT_CCx) (or TIM_DMA_Cmd(TIMx, TIM_DMA_CCx)) 7. Call the TIM_Cmd(ENABLE) function to enable the TIM counter. 8. Use TIM_GetCapturex(TIMx); to read the captured value. Note1: All other functions can be used separately to modify, if needed, a specific feature of the Timer.
