I am trying to configure the RTC wakeup functionality to wake the system from STOP2 mode every 60s. I am using the 1 Hz ck_spre clock and setting the WUTR register to 60 using the HAL api HAL_RTCEx_SetWakeUpTimer_IT(&hrtc, 60, RTC_WAKEUPCLOCK_CK_SPR...
STM32F4 two PWM pulses with different lengths by using DMA
Good evening ST experts, I hope that some of you can help me with my problem.As the titel already states, I am trying to generate two pulses with different lengths (same length, but different CCRs) by using a DMA timer function:HAL_TIM_PWM_Start_DMA(...
