LL_RCC_GetTIMClockFreq doesn't account for the APB Prescaler - is this correct?

I'm writing an application which uses a timer (TIM2 in this case) to track communication timeouts. So the timer period changes periodically, it might be an inter-byte gap timeout at one point and an inter-packet timeout the next.I'm using LL_RCC_GetT...

I have to interface the following in my application: Ethernet – 1 no. SD memory card – 1 no. IOs 24 UART (Serial) – 1 no. LCD – 1 no. And microcontroller selected is STM32F429ZIT6. Please suggest the evaluation board.

HAL_UART_Receive() on STM32F407 is receiving only one byte a time irrespective of amount of data being transmitted on transmitter side.

Hello,Am using STM32F407 (Discovery board). This is connected with a PC which is sending 100 bytes of data and realized that only 1 byte is received and remaining 99 bytes are lost. Below is the code excerpt running on STM32F407      while(1)      { ...

Image overlapping flash banks on STM32H745

Hello,We are using the STM32H745 dual core series, and have an image size that is nearing the single flash banks limit of 1MB. We won't be using the swap bank feature at any point. Will there be issues if the image overlaps the second bank?

CAN messages lost in the way

Hello Everybody,I'm building a device who need to transfer a bunch of datas on a CAN bus at 250bauds.When I get the datas from my buffer to create the messages, it seem that some are mission (I'm sniffing the CAN bus with a can-bus shield from seedst...

QSPI - Clock starts before chip select is set

HiI am using the QSPI to interface FPGA.The setup includes STM32F769I-EVAL board wired to MAX10 evaluation board.The QSPI is configured to indirect mode, data phase only. I was able to read data from the FPGA, control clock speed and set number of by...

stm32f767igt doesn't erase the flash

Hi All.I work with stm32f767igt for using flash.The code below is erasing and writing flash.I succeed writing the flash.​But when i try to delete the flash with HAL_FLASHEx_Erase(&EraseInitStruct, &SECTORError) ;andFLASH_Erase_Sector(FLASH_SECTOR_10 ...

Can you share the MTTF of the STM32H750 ?

Can you share the MTTF of the STM32H750XB ? This is required for some of the CE certification for my product. Regards,
