Resolved! Timer Frequency is not predictable

I am using STM32L496ZGT6P. When using DAC along with DMA to generate voltage and frequency of my desired range. But I am unable to get hold of the frequency setting. Sysclk I set is 4Mhz. 20 is prescaler value, 4Mhz/20 = 200000.This is further divide...

why STM32F303 stop at HAL_TIM_Base_Start_IT(Help)

I found a issue.if the code isHAL_PWR_DisableSleepOnExit();HAL_TIM_Base_Start_IT(&htim2); it will stop at "if (IS_TIM_SLAVE_INSTANCE(htim->Instance))", but i didnt set break point at here.if i change code:HAL_TIM_Base_Start_IT(&htim2);HAL_PWR_Disable...
