Passing multidimensional arrays over HAL UART

Hello,I have a 246 x 3 matrix that I have filled with counter values in the below for loops. I for some reason cannot get the HAL_UART to output individual columns of this matrix. for(i=0; i<246; i++) {   for(j=0;j<3;j++)   {   Audio_Data[i][j] = c...

Reset after flashing emtpy STM32G041 always jumps to bootloader instead of application, until power-cycle.

When an empty STM32G041 (others may have the same problem, couldn'T test) is flashed with an application, an real power-cylce is needed to actually start the application. Until this power-cycle, ever reset (HW or SW) will jump to the bootloader.After...

Good afternoon, please tell me what role the USBD_HandleTypeDef type structure plays in the USB driver

Hello,I'm currently trying to use the "X-CUBE-CLASSB" package I'v found there : X-CUBE-CLASSB - Class B 60730-1 and 60335-1 Functional Safety Package with software expansion for STM32Cube - STMicroelectronics to do some watchdog, stack and flash secu...

Ethernet on ST STM32H747I Discovery board

Hello, I am working on the ST STM32H747I Discovery and I have a question regarding Ethernet. According to the ST documentation (https://www.st.com/resource/en/user_manual/dm00504240.pdf), some hardware modification is mandatory to manage Ethernet. Ho...

How Does This USB Transfer Code Work for Packets > 64?

I have a USB HID device based on the STM32L432 that I inherited maintenance on. My particular device has a HID Report Descriptor that is greater than 64 bytes. I'm debugging using an ST-Link and single-stepping, trying to figure out how the code hand...

Non blocking or Event base programming for MCU in C is possible?

for MCU time is very important to do task.in programming instead of blocking time of MCU we can do other important task how can i do in c programming language?ex: HAL_Delay(); block code execution vest of MCU time.while() waiting for sensor IP etc....

What library/template is a good starting point for development of a USB composite device on STM32F469VI?

We are using STM32F469VI for developing a device which uses the following peripherals:GPIOUART (probably around 3 of them)SDIO (SD card in device, requiring FatFS access as well as mass storage via USB, see below)USB (2 ports)I2CWe would like to conf...

How to boot from and execute code from external Quad SPI flash memory on STM32H742 (STM32H7) using XiP model?

Hi all,we're planing to use an STM32H742 with external SDRAM (for data) and external Quad SPI flash.The Quad SPI flash shall hold the application binary - i.e. instructions, constants, etc. to be loaded at boot and all code to be executed.We'd like t...
