Hi all,I was reading through the documentation of the STM32H723 to find out what clock speed I can configure the FMC to run at using an external SDRAM. Looking at older posts and videos there is mentioned 100 MHz, but when I look at the newer/revised...
I have read AN4991 and the example code but in my case nothing works. I'm using DMA transfer with the UART. Can that be the reason? Is it not possible to wake up from STOP1 when using DMA to receive bytes from USART? Or how can it be done?I use C...
Hi all,My goal is to have position independent binaries for my application (on an STM32H7) so that I can update the device while running out of flash (swapping between two different program locations).I followed this tutorial: https://techblog.paalij...
This is a problem about the STM32H745XI-Disco control external AD5791 through SPI. When using Debug to detect the serial port output, the result is consistent with the desired result. However, when using a multimeter to measure the output of the AD57...
Hello STM community,I have a problem with my Nucleo-G431KB. I am trying to communicate to a sensor device over SPI. The problem I have is that when I use PA5 as SPI1_SCK, the logic high is only 1.4 V instead of the 3.3 V on other pins. When I configu...
I AM USING STM32F407G-DISC1 BOARD FOR DEVELOPING CUSTOM BOARD.HERE AN OSCILLATOR IS CONNECTED TO PH1 AND PH2 PINS. IS IT IS COMPALSORY FOR DEVELOPING CUSTOM BOARD?
Question about HAL_SPI_TransmitReceive timeout.Currently, a timeout occurs when calling HAL_SPI_TransmitReceive in our program. (We are the master)What are some of the factors that cause a timeout in HAL_SPI_TransmitReceive?
Hi STM Expert, We are currently working on STM32G491KCU6 MCU FDCAN side. Our requirement is to validate the activity on Tx and Rx pins. We started off the testing with the LoopBack mechanism but unfortunately we were not able to see any data received...
Hello,in order to use external memories, is it mandatory to use the FMC?Thank you
I am working on a board containing two STM32F412, and I am having a hard time reaching the DFU bootloader:If I power off the board, pull the boot pin low, and then power on the board directly via USB, then cubeProgrammer is able to connect to the boo...
