STM32 MCUs Embedded software

STM32 setup with 2 x HS controllers

Hi, I'm trying to implement stm32f7 discovery cube package example. (USB Mass Storage) in High speed mode. I inserted microSD card into slot. after i build and load the image into the memory , i can see the files inside microsd card.

but when i start to copy and paste these files to another location . i can not get the true speed. (while writing reading) I mean I choose HS mode (60Mb/s) but transfer speed is too low. I made everything in the readme.txt file. but i can not impleme...

How to execute a program uploaded with JTAG on a target configured to start bootloader

 Hi, We received a custom board built around a STM32L476 MCU. I could program it with a basic "Hello World" program which aims at blinking some leds. But the leds do not blink... :( using debugger, I noticed 2 strange behaviors 1) call to HAL_Delay()...

I will use with my STM32H745 Disco Board the eMMC memory together with the Flash File System.

I wanted to use with my STM32H745 Disco Board the eMMC memory together with the Flash File System. In compare to (https://community.st.com/s/article/how-to-create-a-file-system-on-a-sd-card-using-stm32bubeide), the selection for the hardware is graye...

STM32H743 Ethernet issue

Got a problem with ethernet on my custom board with STM32H743BIT and DP83848 PHYeverything 'seems' to work, but I see no outgoing traffic from my board on wireshark.Rx working though, screenshots attached.I read an articlehttps://community.st.com/s/a...

HAL_OSPI_Command_IT vs HAL_OSPI_Command, when cmd->DataMode != HAL_OSPI_DATA_NONE

Hi, dear colleagues!I use OSPI interface to connect MCU with QSPI NAND flash.For some commands (for ex. PAGE READ) of used NAND device there is 0 data bytes and HAL_OSPI_Command_IT() work proper.But some commands (for ex. SET FEATURE) has one (or mor...

I am just about to start a journey as embedded software developer, and I am trying to familiarize myself with a STM32L1 discovery kit - the initial feeling is one of bewilderment.

After I successfully attached the board to my laptop and ran the "Press a button to ...." tests my plan was to proceed to the source code of the demo application:To read through the source code to familiarize with it.To compile it on my laptopTo flas...

HAL_UART_Receive_DMA(&huart1,... and HAL_UART_Receive_DMA(&huart2,.... Usually work well but not if I use in the same program TIM2 with the following instruction HAL_TIM_Base_Start_IT(&htim2).... The timer TIM2 keep working.

STM32F769i-disco - is there a way to tell if the board is connected to USB like by using vbus or another facility?

I'm really trying to tell if the board is connected to an external comm port to turn off usart sends so they don't potentially backup and slow things down. I know other products expose thinks like vbus sensing? Don't know much about it. I tried to...
