How to send audio over Ethernet to STM32F429ZI board?

My laptop act as server and my board (both the end are using statically configured IP) should receive the audio through Ethernet and store it on OTG USB drive.

Resolved! enum declaration errors trying to compile a CAN app using stm32f4xx_hal_can.c

I'm building a CAN app with STM32CUBEMX and TrueStudio. I'm using interrupts so need to register my calback funcs. I put #define USE_HAL_CAN_REGISTER_CALLBACKS 1 at the top of main.h. The following line in my code:HAL_CAN_RegisterCallback(&hcan1, HAL...

USB CDC: How to avoid windows from creating a new COM port for every device?

After updateing to new CubeMX 5.1 my STM32F437 devices acuiring new COM ports per device.It seems that device serial string descriptor is filled by CPU UID instead of hardcoded 00001A value. The PID is 5740, VID is 0483. THis causes the USB stack on ...

HAL_UART_DeInit() behaves unexpectedly

Hello,I have several UARTs when initializing them all simply with HAL_UART_Init , each with its own UART_HandleTypeDef instance, than things works fine.But on adding HAL_UART_DeInit before HAL_UART_Init (this is actually the generated code from stm32...

Resolved! In stm32l4xx_hal.c, there is a bug with HAL_SYSCFG_EnableMemorySwappingBank().

The code is identical to the Disable version. The enable swapping is currently this:void HAL_SYSCFG_EnableMemorySwappingBank(void){ *(__IO uint32_t *)FB_MODE_BB = 0x00000000UL;} and instead of = 0, it should be the equivalent of 0x100.Also, the lower...
