Architecture understanding of STM32H757 MCU
we started evaluating the controller architecture with respect to our application requirement. We are referring application note AN5557, Reference manual for the suggested MCU.While referring the documents, we understand that there are 3 Domain in th...
How are the timers configured for STM32L1 TS hardware acquisition?
I want to test TS with one normal touchkey. I use the STM32L152RETx on the Nucleo-L152RE.I want to use hardware acquisition mode to keep the CPU in sleep mode until a touch is registered. As I understand the UM1913 the L1 series is using TIM9 and TIM...
Why the SDMMC1_IRQHandler can not trig when in IDMA mode read/write by using HAL lib in my STM32H750 project
Hi, Team,It can running the polling mode function HAL_SD_ReadBlocks successfully in my hardware/software platform. When switching to IDMA mode with HAL_SD_WriteBlocks_DMA, the 1st block data could being read out correctly but without the SDMMC1_IRQ...
How to use correct clk in proteus?
I am simulating stm32f103c6 in proteus,I want to do timer2 interrupt ,I set pre = 7200-1,psc = 10000-1,so 1s to timer2 update interrupt.But time is not correct,it does not work.I look up information,it is said I need to change stm32 clk to 8MHz,not...
Resolved! TIM PWM CCR DMA get Transfer error
I am trying to use dma with timer 2 in order to change the dutty cycle of a pwm output in each cycle. However, I get a dma transfer error.
Increase Rx FIFO0 and FIFO1
Hi,I'm using the FDCAN2 of the STM32G474VET6 for a project and I need to reshape the RAM Message memory in order to adapt it to the FDCAN Classic.Actually the configuration of the RAM Message, by default, is written for FDCAN. So I have the following...

Hello, I need to find a free CANopen stack. I have found CAN festival, but I can not figure out how to configure it for STM32. I would appreciate any help. Also, please advise on any other free CANopen stack for STM32.Thank you and best regards,Vouri...
Resolved! What is the output pulse duration of the TIM1 TRGO 2 compare pulse mode?
Hi,I want to confim the pulse duration fo the TIM1 TRGO2 compare pulse. I used the TIM1 trgo2 to trigger the ADC. The TIM1 clock is 64MHz and the ADC clock is 32MHz, the sampling time is 7.5 ADC clock.I want to set the ADC trigger mode is "01", but i...
