LWIP STM32
45 USD Project for sending an HTTP GET request to a remote server every 15 seconds with receiving and processing the result.
The project uses the Nucleo STM32F446RE board, ENC28J60 ethernet module, and FreeRTOS.
At the moment, I have implemented approximate functionality, but it does not work completely.
The project initializes the enc28j60 module, obtains an IP address via DHCP, establishes a connection with the server, and sends a request, but does not receive a response. If the request is incorrect, systems like cloudflare send an error, and the microcontroller receives this message.
Therefore, the minimum requirement in the project is to solve the problem of receiving a response from the server and the microcontroller hanging after 40 seconds of operation. If necessary, restructure (move lwip to a separate thread) and make other improvements.
