STM32H743 (I/O direction control of SDMMC CMD signal)

I'm thinking of getting STM32H743 to work Wi-Fi module via uSD.However since I can not get my Wi-Fi module responding I start questioning my design.​SDMMC POWER.DIPOL control but can change the polarity of CIDR, D0DIR, D123DIR,Is there a way to chang...

STM32F7 resetting during flash operation

I have a project that was working at one point but is no longer working. I think I've narrowed the issue down to a couple of flash operations that happen during setup for Azure IOT. If I let the system run normally it will keep resetting and not run....

What is the reason for have two SRAM in the STM32L476 microcontroller?

I'm learning about the STM32L476 microcontroller and saw that it has two SRAM memories. What is the reason for that? I also see that it's possible to enable parity check on SRAM2. How come, is SRAM2 unreliable?

stm32f7 as spi slave

Hi. I am trying to work with AD7763. I have the same problem as in this article, but there are no answers in it. https://community.st.com/s/question/0D50X00009Xkfaw/spi-oneway-communication-slavemaster?t=1639997683527So AD7763 is master and stm32f7 i...

Hello, I am making a CUSTOM HID Keyboard application with the stm32f103 processor, when I add the media keys (volume reduction, increase, etc.) to my project, the function that reads the status of the following leds with event_idx does not work. HELP!

this is leds status code ;static int8_t CUSTOM_HID_OutEvent_FS(uint8_t event_idx, uint8_t state){ /* USER CODE BEGIN 6 */if( (event_idx & 0x01) == 0x01 ){HAL_GPIO_WritePin(GPIOA,GPIO_PIN_10, GPIO_PIN_RESET);}else if( (event_idx & 0x01) != 0x01 ){HAL_...
