Hello,I'am currently programming on a STM32G473. I'am sending CAN Message via the FDCAN peripheral.In generally everything works, all my messages I put into the Tx Buffer are sent.But in one little detail I'am confused:In Figure 669 its described, th...

Hello,I have a problem on a STM32H753 which I do not understand.I want to sample some data from ADC with a given time period.So I use the TIM2_TRGO as Event generator for the ADC3 (via EXTSEL)ADC3 is configured in 12 Bit single conversion, in the seq...

Hi,I've been struggling with using the STM32G473's internal comparator and DAC for a few days now.ComparatorI use the internal COMP1. For the negative Input I selected the DAC3-CH1 and for the positive input I selected the Pin PA1. PA1 is configured ...

I am using STM32CubeIDE V1.11.0I have exactly the same issue which was described in this post:https://community.st.com/t5/stm32-mcus-boards-and-hardware/st-link-gdb-server-issues/m-p/64010#M623Multiple weeks everything works fine. But suddenly it sto...

Hello,I bought a NUCLEO-H743ZI2 board.When I plugged it in for the first time, I was able to flash it after two or three attempts (ST-Link was often not recognised).But now the STM32CubeProgrammer does not recognise the ST-Link at all (I have tried m...

@Oleksii: I dont think so. There is a dedicated Bit TXFQS_TFQF which is the "Tx FIFO/Queue full" indication.

Hi,ST support was able to help me.You are right. Its a problem with the D-Cache. The D-Cache does not recognize that the DMA has changed the RAM content. If you try to read the data, you only get the D-Cache Date. So you have to invalidate the D-Cach...

Maybe some additional info:I also tryed it with ADC1 and ADC2, but still have the same problem.traceObj->data is placed in SRAM3, beginning from address 0x30040000.So in this case all used peripherals are in D2 Domain (DMA1, ADC1/2 [AHB1], SRAM3) I r...

Maybe it is the same issue I have?Does your DMA maybe transfers no Data to the SPI peripheral?https://community.st.com/t5/stm32-mcus-products/stm32h753-dma-sometimes-does-not-transfer-data/td-p/681583

Hi, yes I made progress and found the problem.In my case there was an aditional ADC measurement at Pin PA1 active.So the Sample&Hold capacitor of the STM internal ADC has shifted the Signal for COMP IN+ at each time of conversion. It seems that the S...
