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 ...
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 ...
i am generating a pulse using gpio pins ,how i can change the frequency ?
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...
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...
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...
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...
Could you give me a parameter sheet for "STM32H750VBT6" and "STM32H730ZBT6"?Required for export.Thank you.
I managed to program the FLASH_OPTR user option bytes and set the SRAM2_ECC to zero (enabled). But when restarting the µC the RAMCFG_M2CR ECCE bit is not set and the RAM ECC is not active. So during startup when the .data section is initialized in SR...
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...
