APPLICATION OBJECTIVE:The objective is to monitor a high-frequency signal in the range of 0 to 50 MHz from an external device and count the signal pulses every 10 microseconds windows/bins.Platform:STM32F7APPROACH:The current approach is to configure...

Hi everyone Question: suppose one sets up a DMA transfer from a Timer1 register to memory so that it gets executed when timer event is raised. What happens first:the peripheral to memory DMA transfer is executed ?or the Timer registers are updated?...

Hi everyone,I am trying to implement a system that counts pulses that can be as narrow as 20 nanoseconds using an STM32F746 MCU clocked at its max 216MHz.The first thought was: "Can such narrow pulse even be detected by the MCU?"To confirm, and inspi...

SOME RANDOM THOUGHTS (even if true not sure how to debug them):Could TIM3 for whatever reason generate a fast stream of TRGO events which TIM1 senses in its ITR and its DMA transfer is triggeredCould it have something to do with:SMCR :: Bit 7 MSM: Ma...

Both previous answers were useful and would mark both as "Accept as Solution" if I could.Thank you!

Slave Timer ETR pulse counting

STM32F746: behaviour of from Timer to Memory DMA transfer when timer event occurs

Noob doubt: Is a timer clock frequency relevant for input edge detection?
