W5300 Ethernet for Arduino

Overview

The W5300 TOE examples use W5300 TOE Shield - ethernet I/O shield compatible with STM32 Nucleo-144 board built on WIZnet's W5300ethernet chip, and STM32 Nucleo-144 board.

• W5300 TOE Shield

STM32 Nucleo-144 boards support the list below.

• NUCLEO-F429ZI

And W5300 TOE Examples support two IDEs.

※ Please select and use the IDE according to your dev. environment.

Description :

• ARDUINO W5300: INO-based example implemented using ARDUINO IDE.
• PlatformIO W5300: CPP-based example implemented using PlatformIO.
• ARDUINO for STM32 Project

Reference: https://github.com/stm32duino/Arduino_Core_STM32/blob/main/README.md This repo is available as a package usable with Arduino Boards Manager.

Add this link in the "Additional Boards Managers URLs" field: https://github.com/stm32duino/BoardManagerFiles/raw/main/package_stmicroelectronics_index.jso

• Replace existing Ethernet and FMC library with this W5300 library path: C:\Users_YOUR_NAME_\AppData\Local\Arduino15\libraries
• PlatformIO for STM32 Project

Make PlatformIO Project for STM32F4 Series (for example: select NUCLEO-F429ZI board).

• Make PlatformIO Project for STM32F4 Series (for example: select NUCLEO-F429ZI board).

Follow the README in the PlatformIO's directory and folder.

• Follow the README in the PlatformIO's directory and folder.

This library have to locate in lib path.

Hardware requirements

The ethernet examples use NUCLEO-F429ZI build on STM32 MCU with WIZnet's [W5300][link-w5300] ethernet chip. If you use other STM board, supported board of STMicroelectronics micropython in [LIST][link-suppoted_stm] and check that the board supports FMC 16bit data.

Pin Diagram

STM32F429ZI This document is based on STM32F429ZI. If you use other STM board, Please edit it to your HW configuration. 📷

• FMC Data pin (0-8 or 0-16)
• FMC Address pin (0-10)
• FMC Control GPIO pin (NE, NWE, NOE)
• WIZChip Control GPIO pin (INT, RST)
• UART3 pin(connect to ST-LINK) -- Be changed for use the FMC on the Nucleoboard. Pin D8,D9 -> Pin C10,C11

Development Environment Configuration

Setup ST-LINK

The ST-LINK pin was changed due to overlapping use of the FMC(Flexible Memory controller) data pin to control the W5300 built in the W5300 TOE Shield and the ST-LINK pin of the STM32 Nucleo-144 board.

• STLK_RX[STM32F103CBT6_PA3] : PD8 → PC10
• STLK_TX[STM32F103CBT6_PA2] : PD9 → PC11

Therefore, in order to use the ST-LINK of the STM32 Nucleo-144 board, minor settings are required for the W5300 TOE Shield and STM32 Nucleo-144 board.

• Remove SB5 and SB6 from the top of the STM32 Nucleo-144 board.

• With the W5300 TOE Shield and STM32 Nucleo-144 board combined, connect PC10, PC11 of the W5300 TOE Shield and CN5 TX, RX of the top of the STM32 Nucleo-144 board with jumper cables.
• W5300 TOE Shield : PC10 - STM32 Nucleo-144 board : RX
• W5300 TOE Shield : PC11 - STM32 Nucleo-144 board : TX
• Modify STM32 packages' variants code for Serial

Step 1: Prepare IDE

The ARDUINO an PlatformIO(built-in VSCode) support the serial monitor. So you need not prepare serial terminal program

Step 2: Prepare hardware

Combine W5300 TOE Shield with STM32 Nucleo-144 board.

• Combine W5300 TOE Shield with STM32 Nucleo-144 board.
  

Connect ethernet cable to W5300 TOE Shield ethernet port.

• Connect ethernet cable to W5300 TOE Shield ethernet port.
  

Connect STM32 Nucleo-144 board to desktop or laptop using 5 pin micro USB cable.

• Connect STM32 Nucleo-144 board to desktop or laptop using 5 pin micro USB cable.
  

Step 3: Setup Examples

To test the examples, minor settings shall be done in code.

• Choose the demo application.

< sample > a. ARDUINO: To run the ChatServer example, you must double click the ChatServer.ino in 'Ethernet/examples/ChatServer' directory.

b. PlatformIO: To run the ChatServer example, you have to move the ChatServer.cpp in 'Ethernet/examples/PlatformIO_CPP_Examples' to 'Your PlatformIO Project Path/src/' directory to build.

• Setup network configuration.

Setup your network configuration in the examples such as IP of 'ChatServer.ino' or 'ChatServer.cpp'in project directory.

byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
IPAddress ip(192, 168, 11, 111);
IPAddress myDns(192, 168, 11, 1);
IPAddress gateway(192, 168, 0, 1);
IPAddress subnet(255, 255, 0, 0);

Step 4: Build and Download

After completing the ChatServer example configuration, build in the IDE you are using.

• After completing the ChatServer example configuration, build in the IDE you are using.
  

When the build is completed, download the firmware to the STM32 Nucleo-144 board.

• When the build is completed, download the firmware to the STM32 Nucleo-144 board.
  

Step 5: Run and Samples

• Connect to the serial COM port of STM32 Nucleo-144 board. Default Serail speed was set to 9600 by example codes.

You can easilly see the network data by Hercules. Download: https://www.hw-group.com/software/hercules-setup-utility
