Resolved! STM32H743 kein CAN-Datenempfang mit 1MBit

We have a project which reads CAN data on both FDCAN ports. Bitrate 500 kBit is working perfectly, but with 1 MBit no data can be read. PIN-Speed = HIGH (also tried MEDIUM and VERY_HIGH, but no change)CAN-Clock = 80 MHzWe already tried CAN Bittiming ...

Resolved! The timing for reading the ADC with DMA seems way too long. I calculate just under 36 us to read 8 ADC channels with a STM32L443CCT running at 64 MHz.

I am trying to trigger every millisecond, or 1000 microseconds, but my counters in the interrupt are seeing 167 interrupts per second as opposed to the expected 1000 interrupts per second.I am reading 6 channels with a sample rate of 92.5 clocks per ...

STM32F103 not programming

Hello i am working on a project which is based on stm32f103c8t6 mcu.i face a issue while programming some of these microcontrollers.sometimes some microcontrollers are programmed perfectly while some start giving errors(see attachment).while going th...

Can I put read/write variables in DTCM, when DCache enabled?

If DCache is enabled how then can I update a variable (I think DMA + MDMA) and after processing get results to a peripheral e.g. DAC (again MDMA?)?Do I need to clear cache?Will I still have the speed advantage of caching?I am struggling how to get d...

Resolved! Cannot cofigure the ADC on STM32L431KB. ADEN always set to 1.

Hi,I am having trouble configuring the ADC on my STM32L431KB. The calibration procedure appears to go well until it gets to the step where the program waits for the calibration to finish. It is never able to finish. I think the problem may be related...

Resolved! STM32 PWM Generate when Input Capture Update Event

Hi, I'm doing a project with STM32F769I-EVAL.In my project, I set Timer 2 Channel 1 to input capture mode, and I made a clock to TIM2 CH1 Pin with Function Generator. And Timer 5 Channel1 to PWM Generation CH1 to make a PWM.I calculate frequency of i...

How to restart an STM32 timer halfway with a new value?

I have a timer which at each interrupt first stops itself, and then set its own next delay:HAL_TIM_Base_Stop_IT(&htim); // do stuff __HAL_TIM_SET_PRESCALER(&htim, new_p); __HAL_TIM_SET_AUTORELOAD(&htim, new_a); __HAL_TIM_CLEAR_FLAG(&htim, TIM_FLAG_UP...
