Hi I have a STM32L433 running at 16MHz and having a strange issue. I have setup the rtc and within the Systimer interupt I display the current time (the systimer is 1KHz and every 1000 ticks I get the second , at this point I read the clock and di...

Hi I am using a STM32L433 and have a digital input pin, which is checked on bootup and enables the USB if 3.3v is in the pin. When working in debug mode, it always works, but when I switch to release mode , using stm32CubeIDE , it always reads 0v,...

Hi I have found the issue, after anytime the CR was updated the INIT bit was set for a short time, but enough to cause a delay. The way around it was to clear the INIT bit before locking the RTC registers again. ThanksScott

I added the line:__DSB();after the clocks being enabled, but never made a difference. But when I added a 2ms delay after GPIOB->MODE and this worked.Where do I add the DSB command, and is it just the DSB() on its own?CHeersScott

Many thanks for your reply.I havent come across this before, do I call it for all clocks, or is it 1 command takes care of it all?I can add "__DSB();" line to my code, is that all is needed? RegardsScott

Many thanks for the reply. I will add a delay. ThanksScott

Hi ,what is _DSB? What do I check ? Is it if the B clock is enabled? And if its not what do I do if its not enabled? Sorry for all the questions. Scott
