What to use for HAL_SAI_Receive Size parameter?

Hi, I'm trying to work with the SAI HAL interface, i have set the black frame to 64 bits wide and the block slot size to 32B.When using the HAL_SAI_Receive() function, what does the length parameter represent?For my solution i am sending 2 32bit slot...

Hi i pursuing master degree. i m just a beginner of stm32. i do only led blinking on my board stm32g431rb. i need help to perform serial communication . i dont have any clear ideas . please help me .

STM32F74 vs STM32F7: Dual Bank Mode

I'm trying to get dual bank mode to work on an STM32F74. According to application manual AN4826 all STM32F7 series devices should be able to use dual bank mode. However, the reference manual for STM32F74 doesn't mention dual bank mode or Read-while-W...

Can you support 216MHz when using STM32F746 1.8V?

Hi all,​I am using STM32F746I want to check if it can be used at 216MHz when using at 1.8V.There is some confusion on the data sheet that makes it difficult to determine. (Attachments)Please help me ~Thank you,Best regards.​Gyosun.

What is the point of high CPU frequency when Flash Latency slows the CPU down?

I just got started with STM32 and I was trying to make 1 second delay with " for() " loop  based on CPU frequency with STM32F407 . I realized It takes more clock cycle to perform one loop in higher frequencies than lower frequencies. For example  " f...

Program JTAG-DP on STM32F102xx

We want to use the STM32F10x MCU as a JTAG dongle. Can we make use of the TDO, TDI and TMS on the chip or they are use solely for M3 debugging? Thanks.

I am trying to process video signal from a linear CCD, is it possible to add two stop bits to the end of the digital output signal?

I am looking at options to replace my mostly obsolete design using an FPGA and old linear CCDs. I've already chosen a new linear CCD chip but I'm considering a handful of processing options. Our CCD alignment system currently uses 13 bits output to o...

QSPI Interrupts not working with example projects

Hi,I'm using the STM32746 Discovery board and some example code - the "QSPI_ReadWrite_IT" example - but the QSPI interrupts are not working correctly. Specifically the Status match interrupt never fires and the example code gets stuck. I've ported ov...

How can I handle FIFO0 pending bit interruption ? How can I clear the flag correctly ?

Hi all, I'm using a stm32f10x connected to a CANalyzer in order to verify the integrity of the CAN bus. The implemented process is simple, I have transmitted a CAN trace ( 11 bit ID + 8 bytes of DATA ) to the CANalyzer and it responses automatically ...
