VN23 – Stm32F4 Input Capture DMA ( 2 timers + 2 channels )

VN23 (Video No:23) This video is about, (Hal lib V2.11.0) while programming STM32F4 with STM32CubeMX – Keil, how to use input capture DMA method? What should we put attention to, while using DMA FIFO? I used Timer1 channel 2 ve Timer2 channel 1 in the video.

 Notes;

• When Capture event occurs, related timer count value is saved in capture register.
• When Capture event occurs, related timer count value should be set to zero “0”.
• For DMA FIFO settings, FIFO threshold configurations ( RM0090 reference manual Table 48.) must be taken into attention.

• If FIFO settings are wrong, DMA is disabled automatically.
