I'm using a STM32F746-disco and lwip to communicate with and another embedded system (a commercial standalone air monitoring system).When the two are connected via a switch the STM32 can Ping, get web pages via HTTP and get FTP files from the industr...
HiI see sleep/awake cmd is implemeneted in HAL fpr STM32H7only.Now I ported it myself to Stm32f446 myself successfully. However instead of while loop below, i inserted a HAL_Delay(1);H7 has a SDMMC but Stm32f446 has a SDIO.In the H/ HAL bit SDMMC_FLA...
Hello STM community,I'm working on optimizing SPI communication on an STM device, and I'm encountering an issue with the timing of SCLK pulses. After transmitting 16 SCLK pulses, there's a delay of 3μs before the next set of 16 pulses can be generate...
This was a tricky bug to find. I am doing context switching. Everything seems to working well until a context switch happens while one of my tasks has called a different function. Specifically, HAL_GetTick(). To be clear the switch is happening while...
I am working on a port of the STM32L5xx Open-Bootloader for the STM32L4xx MCUs so that I can disable some of the peripherals that I am not using. While working on the port, I had some questions about the memory regions defined in the openbootloader_c...

Hi,How would one go about giving access to hardware handles in source files other than `main.c`? For instance, the ADC state is stored in a struct called `hadc3` in `main.c`, without an access modifier. I would assume that this is extern by default, ...
I AM USING A ETHRNET ON STM32H734ZI BUT ETHERNET CONTINUE WORKING FOUR DAY ON MY DIVICE AFTER STOP MY DEVICE WORKING SO I CAN NOT FIND MY SOFISTICATED SOLUTION IN ETHERNET PLEASE GIVE MI SOLUTION
Hi - I'm using HAL_GetTick(), and then subtracting one value from another to determine a GPIO input pulse width.What happens if I happen to to call HAL_GetTick() around the point where the SysTick timer rolls over through zero.Do I need to watch out ...
Hi,I have an UDP Server on a STM32H743ZI. It works very good only if the ethernet cable is already connected when I power on the board.However, if I connect the cable after powering on the board, UDP Server does not receive any message.FreeRTOS is us...
