Overview
The Ditel_W5500 project integrates the W5500 Ethernet module with the STM32 Nucleo_F446RE board, offering network functionality examples. It primarily uses SPI communication to control the W5500 module, enabling dynamic IP address allocation via DHCP or static IP address configuration.

Key Features
- DHCP Support: Obtain IP addresses dynamically through DHCP.
- Static IP Configuration: Manually set IP, gateway, subnet mask, and DNS server addresses.
- UDP Communication: Open UDP sockets and send/receive data.
Code Details
- DW5500_init Function: Initializes SPI and GPIO pins and sets network information. It supports both DHCP and static IP configurations.
- SPI Control Functions:
_DW5500_Select
and_DW5500_Unselect
manage the CS pin for SPI communication. - Data Transmission Functions:
_DW5500_ReadBuff
and_DW5500_WriteBuff
handle data transfer via SPI. - DHCP Callback Functions: Handle IP assignment verification through DHCP.
- UDP Functions: Initialize, open, close, and manage data transmission over UDP sockets.
Usage Example
The project includes example code for using the Nucleo_F446RE board, demonstrating W5500 module setup and UDP communication.
Project Structure
- Core Folder: Contains essential library files.
- Example/Library-W5500-Nucleo_F446RE Folder: Provides example code for the Nucleo_F446RE board.
Installation and Setup
- Configure SPI and GPIO using STM32CubeMX.
- Compile the example code and upload it to the Nucleo board.
- Connect the Ethernet cable and verify network communication.
This project serves as a valuable reference and example for developers looking to implement simple network communication using the W5500 Ethernet module. For more details, visit the Ditel_W5500 GitHub page.
