STM32 MCUs Embedded software

I want to try SPL2LL-Converter under Windows - but how can I start it??? Luckily, I have Oracle JRK but it doesn't help much, because GUI is disabled (grayed)

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

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...
