I want to count external pulses for one second.On STM32F030 / HAL-Lib I did not findatomic read/reset countercapture by a second timer did not work, thoug I studied well and tested a lot how to config it by STM32CubeIDEIs there any example for a high...

Hi JW,thanx to Your Schnitzeljagd-Hints I was able to implement an interrupt on counter-overrun / update event (htim_count) and count almost precisely fom 0 to 130000 pulses within 1 second. The second timer (htim_int) interrupts each second and then...

For my tests I am using stm32l412kb because I have an eval board with it here. But I want to use stm32f030 in my final design.UDIS is not a harware-driven flag to indicate over(under)run. Quote from Page 780 of RM0394 Rev 4 :" Bit1 UDIS: Update disab...

For the timers on stm32I412kb I did not find any overrun- and/or underrun-flags, nor interrupt-flags for this purpose.

Yes shure.Counting on external pulses by a timer/counter and generating interrupts by a second timer did work quickly. I successfully tested a lot of other stuff as well , just by curiosity. But triggering capture by a second timer and generating int...
