Hi all, I am using TIM1 as PWM output generator, and TIM15 and TIM16 as general counters. A problem has occurred where the TIM15 CC1 and CC2 interrupt flags would become set after initialization, thus triggering the TIM15 interrupt. However, both the...

Hi all, I have encountered a problem where the debug would stop working as soon as the program hits the line where TIM15's update interrupt is enabled. From there the program appears to be still running but would not stop at any breakpoints and live ...

Hello all,I recently ran into this problem where the MCU would instantly stop working after enabling the DAC. The behavior is that from the debug view of STM32IDE the program is still running, but all variable values are reset to 0, and once the prog...

Hi all,I am trying to toggle a IO pin but the pin just will not turn on.I checked register values at startup before main(), and some of the values are the the same as the reset values shown in the reference manual:Every register has been set to the r...

I am trying to use the onboard DAC to generate a sine signal. The program runs without any problem on the Nucleo L432KC board but it would not work on our PCB with L431. As soon as the DAC is enabled with LL_DAC_Enable(DAC1, LL_DAC_CHANNEL_1); the pr...

Hi all,It turns out that high frequency interrupts has caused this problem either alone or in combination with other factors. After changing it to DMA the problem is gone.

Yes, this is it

Hello JW,Below is the TIM15 ISR:void TIM1_BRK_TIM15_IRQHandler(void) { if(LL_TIM_IsActiveFlag_UPDATE(TIM15)) { LL_TIM_ClearFlag_UPDATE(TIM15); LL_GPIO_TogglePin(PH_PORT, PH_PIN); } }

Hi Pavel, no it will not reach that breakpoint. In fact I have added a breakpoint after these 2 lines: LL_TIM_EnableIT_UPDATE(TIM15); //Debug stops working after this line LL_TIM_EnableCounter(TIM15);and it would not even break there

I did forget to connect that pin, so yes it was the problem
