Hi, Is there a way to clear the bxCAN REC & TEC error counters without having to be connected to a fully functional CAN bus?
I have tried resetting the bxCAN module, but that does not affect the counters.I have tried transmitting / receiving CAN messages in silent loopback mode, but that does not seem to affect the REC/TEC values.I am trying to clear the counters offline,...

Why does starting SPI1/DMA1ch2 cause ADC3/BDMAch0 to stop?
The HAL_ADC_ConvCpltCallback interrupts stop firing the moment I start SPI1:SET_BIT(hspi->Instance->CR1, SPI_CR1_CSTART);If I clear spi1's CR1 Start, I get the adc complete interrupts firing again.Since they use different peripherals, not sure how on...
Non-continuous memory RAM on STM32H743II
Hi,I am developing an application running on STM32H743II MCU and I need to use all the 1Mbyte RAM.I tried to define a RAM_region for every SRAMx, this didn't work properly and not managed to build the project successfully.Another issue is that some ...
Problem in communication 2 slaves and 1 master using SPI.
hello everyone, I have a problem in communication 2 slaves and 1 master using SPI.master will send a code to activate one of the slaves and then the master will receive data from the slave, but sending the initial data is always wrong and only when t...
Resolved! How do I properly exit from the fault handler?
I am currently using STM32F746. I am trying to exit from a MemManage fault handler back to the instruction which triggered the fault (I am trying something hacky that properly resolves the cause of the fault inside the handler so going back to the or...
Need informations about how fast DMA2 memory to memory transfer can be.
Hello. The microcontroler used is the STM32F429.There is an 65MHz capable ADC connected to GPIOA pins 0 to 11.Also there is a SDRAM IS42S16400J connected on FMC, that is configured like this :/* FMC Configuration -------------------------------------...
SMPS Clock throttling requirement to initialize
So, I need to implement SMPS for more efficient power use on my STM32L452 MCU. From what i understand, the clock needs to be brought down to 24 MHz prior to any SMPS actions. I am operating the system at 80 MHz, so I need to bring it down to 24 and ...
Resolved! Reading continuously RTC in STM32F4 ar 180MHz
I have problems when I read continuously the RTC time in stm32f446 at 180MHz, after some readings, this gives me the same value. To find a solution, I implement a delay of 1 second to read the RTC and this solves the problem, however, I don't know wh...
