Hello, I'm using STM32F100RBT. How can I use HAL_RTCEx_SetSecond_IT to exit STANDBY mode?I'm able to exit STANDBY using ALARM, and able to get an interrupt every second using HAL_RTCEx_SetSecond_IT , but I can't wake up from standby with it.What shou...

I'm using TIM6-DAC-DMAMUX-DMA to create a periodic signal as shown in the following picture. The yellow curve is DAC output, and green curve is a toggled GPIO for debug. I catched an unexpected interrption time point which is described as followed:

Registers Setting: DMA_S0CR: MSIZE=PSIZE=16bit, DBM=1, MINC=1, CIRC=1, DIR=M2P, TCIE=1, EN=1DMA_S0NDTR = 8DMA_S0M0AR points to a buffer: 0x8000, 0x6000, 0x4000, 0x2000, 0x0000, 0x2000, 0x4000, 0x6000DMA_S0M1AR points to a buffer: 0x7000, 0x5000, 0x30...

ST32F413 undead DMA stream refuses to stop

I have a hang on the line below; the DMA stream seems unwilling to stop.Anybody seen this behavior before? Any work-around?Thanks!Best Regards, Davewhile(DMA2_Stream6->CR & DMA_SxCR_EN) {DMA2_Stream6->CR &= ~DMA_SxCR_EN;};

[L4 TIM1/8] TRGO driven from the plain OCxREF or the combined OCxREFC?

Posted on July 06, 2018 at 15:13The TIMx_CR2.MMS2/MMS bitr description indicates it's the former (OCxREF) whereas the figure indicates it's the latter (OCxREFC)Please clarify.Thanks,JWPS. One chapter further, the following picture probably by copy/p...
