STM32 MCUs Embedded software

Can anyone suggest how to work with both SD card and USB Thumb/flash drive with NUCLEO-H743ZI2 board in a single code?

Why do the client to server transactions in the Nx_TCP_Echo_Server example stop after 4 to 5 messages sent by the client if the nx_tcp_socket_send(&TCPSocket, data_packet, NX_IP_PERIODIC_RATE); call to echo the data back is not made?

I started seeing the problem when I took the working example from pack 2.0.0 (STM32H723NG) and added the UART side of my project. I had also modified some of the NetX code to suit the server application for the client I intend connecting with. Part...

I want to implement FOTA for stm32u5 using bootloader, I am new to the ST ecosystem and it would be helpful if I get some light on this ??????

I am trying to run UART on STM32 MCU using HAL library for one of my application. I would like to receive packet of data which I am not able to do. Can you please guide me in this? I have provide details below.

I have created an application where I can transmit and receive data over UART port one by one. I am also able to receive packets in sets where I know the size of the data.But in my case, I want to receive data packet of unknown length and read from r...

How to implement "POST" request between two stm32?

I have implemented LWIP CGI Server which using "GET" request but to me need implement "POST" request. Could someone to show me an example how to send/receive "POST" requests between two STM32?

Receiving big data over UART, sending it through USB CDC - missing data.

Hello.So, my application contains of STM32F407VG and another CPU (OpenMV H7 if you are curious, but it doesn't matter) that is sending frame buffer from camera over UART. It isn't crucial in my application, but I just wanted to try doing that. So, fr...

I have a question about HAL_I2C_Master_Transmit (I2C_HandleTypeDef * hi2c, uint16_t DevAddress, uint8_t* pData, uint16_t Size, uint32_t Timeout);

Hi, I have a question about HAL_I2C_Master_Transmit (I2C_HandleTypeDef * hi2c, uint16_t DevAddress, uint8_t* pData, uint16_t Size, uint32_t Timeout);I see the second field is a pointer to a 16 bit integer. However the device I am trying to interface ...
