I have quite a complicated case, where a interrupt is beeing executed, allthough it has been disabled, and its flag beeing cleared. At the same time interrupts are disabled, and i put a few nops in between just to rule out any delay related issues. T...

I had an issue, that i could not reproduce, because i could not restore the exact state of the project. The CubeIDE has its own version control for each file, which is of no great use, since the project consists of many files. Because of that i devel...

Hi,i have a micros() function, that i adapted from arduino library. It worked flawlessly so far, but i have made a discovery, that micros() did not work properly at one time. micros() returned a time, that had 772us less, than it should have returned...

Hi,i got quite some difficulties, having this run in a reliable way on a NUCLEO G431KBT6.It more often does not work, as it would work. It often just wouldnt print anything (But it had before, without issues!). Sometimes the swv debugger couldnt be e...

I have now finished my investigation:It is, as i expected, and wrote in the title of this topic:In order for the pending status to be cleared with clearing the TIM_SR_CC4IF flag, interrupts have to be enabled at the same time. This also applies to re...

Allthough your link is not the exact problem i have (i think), it helped me (reading pending states) to get further: clearing the TIM_SR_CC4IF flag did not clear the pending interrupt, i had to clear the pending interrupt too. Is this something that ...

Any ideas what i could look into? What registers, or what tactic could be done?What about the enabling of interruts, why does it make a difference of when the are enabled?

This is how i clear it:CLEAR_BIT(TIM8->DIER, TIM_DIER_CC4IE); 30 NOP´sTIM8->SR = ~TIM_SR_CC4IF;30 NOP´sother codeSET_BIT(TIM8->EGR, TIM_EGR_COMG); //should not matter heredelayMicros(2);When i enable interrupts before the delay, the interrupt does no...

I am very hesitant to update programs, if they are working (at least enough for me;-) ).Too many things are made worse than the were before. BTW. It would be nice, if the forum gets an update, so there wouldnt be empty lines added after each edit of ...
