STM32G4 Comparator Blanking Pulse (frequency change possible?)

Hello,I am using the comparators (COMP2) on STM32G4 and want to add some blanking windows to let the COMP2 input get rid of the system switching noise.The technical manual gives a very brief example as shown in Fig.1.  But I need something more compl...

Dear, We are new design of board with STM32H7 and we need to put external SDRAM using Flexible memory controller (FMC). Could you say me routing rules or routing guidelines ? Thank you in advance

We will use chips with lower data witdh than 32 bits, by this we put multiple chip form the data bus.Could you help me?

I have battery simulator solution written for STM32G071RB microcontroller and would like to know if i can use boards with STM32F4 microcontroller. I guess it depends on pin layout or similar? Thanks in advance Tomislav

STM32 doesn't receive data when using extended ID in CAN_FD

Hi everyone,I am trying to send data from one STM32G0B1 MCU to another STM32G0B1 MCU. When i use standard ID it works perfectly but if i use Extended ID then the receiver interrupt doesn't fire. I also checked it with logic analyzer. Transmitter send...

CPOL & CPHA setting in NSS pulse mode.

RM0440 Rev 7 (STM32G4), 39.5.12 NSS pulse mode.It is written on the page 1753: “This mode is activated by the NSSP bit in the SPIx_CR2 register and it takes effect only if the SPI interface is configured as Motorola SPI master (FRF=0) with capture on...

STM32L151C8T6/STM32L151CBT6 about ISP

Can STM32L151C8T6/STM32L151CBT6 download ISP with one click?Can you provide a reference circuit diagram?

I want to DMA Input Capture (TIM1 CCR1) frequency values towards QSPI i/f (Single SPI Mode, W25Q128JV connected), store in Flash, DMA request being triggered by TIM6 ; on a STM32L412 based board. Need your help...

Hello All,I am adding parts of my code. Storing to flash is working if I DMA TIM1 CCR1 to memory and then copy from memory buffer to Flash.I assumed that writing to QSPI_DR will trigger transfer to Flash.Is it feasible to DMA to QSPI?////////////////...

I want to change external Nor flash Memory. I want to change M29W640GL70NA6E (70ns speed) to EN29LV640AB-90TIP (90ns speed). I am wondering which part needs to be corrected.

I​The MCU I am using is STM32F429ZET6.

how to receive extid and stdid of can message together.

hi everyone :)I'm using stm32f405 with can communication.my work consist of multi devices. and there is STDID and EXTID together.I check complete STDID alone. and EXTID too...but I don't receive together.how to receive these.please help...​
