Dear All,Board: Nucleo - H745ZI-QWhat am I trying to do ?I am trying to measure pulse width of an signal using counter mode of timer 2, as accurately as possible. The input pulse width varies from 1 us to 1000 us.What have I done?I configure the Tim...

Dear All,Board: Nucleo - H745ZI-QWhat am I trying to do ?I am trying to measure pulse width of an signal using input capture mode of timer 2 channel 1. Then multiply that width by two and wait for that much time and generate an output pulse using out...

Dear All,Board: Nucleo - H745ZI-QWhat am I trying to do ?I want to measure pulse width of an input signal using a busy loop and a timer. I keep monitoring a pin configured as input , when a zero is detected (by default input is around 3 volts), a fun...

I have existing working code which uses uart and some GPIO functions. Its main.h has,#include "ll_common.h", #include "stm32h7xx_ll_gpio.h", #include "stm32h7xx_ll_usart.h"and few more ll headers.Now I need to add I2C functionality to the code. I go ...

Thank you.I notice that all of them report having found a clock value more than 8 , that is 8.002, 8.005 etc. MHZ. In such case, I wonder I should get measured pulse width less than the actual, like for example 495/496 us fr 500uS input. Isn't it.In ...

Thank you. I am aware of this method. But input capture feature gives me limited options for using pins and my application has lots of such pulse widths coming from different sources. Also, I am using many pins for functionalities like Key board and ...

Thanks for the reply.Code snippet is added in the post. After reset OC2PE is anyways zero but even after explicitly doing it, same result.Kindly have a look at the code.

Thanks for the reply.Code snippet is added in the post. Thoroughly debugged, TIM register content at all stages is as expected. But output in scope does not follow the time. Also OC2FE is set as suggested but same result.Kindly have a look.

Why measured pulse width using TIMER accumulates error as pulse width increases? (understanding inaccuracies in TIMER)

Issue with reading pulse widths in input capture mode using two timers.

Unable to read correct pulse width using busy loop and timer.

Issue in using two channels of Timer 2, one as input capture and another as output compare.

Undefined HAL symbols, in Keil
