Usage Instructions
The Adafruit Ethernet FeatherWing is easy to use with Feather microcontrollers. Follow the steps below to integrate it into your project:
Step 1: Hardware Setup
- Attach the FeatherWing: Stack the Ethernet FeatherWing onto your Feather microcontroller using the provided headers.
- Connect Ethernet Cable: Plug a standard Ethernet cable into the RJ45 jack on the FeatherWing.
- Power the Feather: Supply power to the Feather microcontroller via USB or a battery.
Step 2: Software Setup
- Install Required Libraries:
- Open the Arduino IDE.
- Go to Sketch > Include Library > Manage Libraries.
- Search for and install the
Ethernet2library (compatible with the W5500 module).
- Load Example Code:
- Navigate to File > Examples > Ethernet2 > WebServer.
- Modify the example code to match your network settings (e.g., IP address, gateway).
Example Code
Below is a simple example to set up a web server using the Ethernet FeatherWing:
#include <SPI.h>
#include <Ethernet2.h>
// Network configuration
byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED }; // MAC address
IPAddress ip(192, 168, 1, 177); // Static IP address
EthernetServer server(80); // Create a server on port 80
void setup() {
// Start serial communication for debugging
Serial.begin(9600);
while (!Serial) {
; // Wait for serial port to connect
}
// Initialize Ethernet connection
if (Ethernet.begin(mac) == 0) {
Serial.println("Failed to configure Ethernet using DHCP");
Ethernet.begin(mac, ip); // Use static IP if DHCP fails
}
// Print the assigned IP address
Serial.print("Server is at ");
Serial.println(Ethernet.localIP());
// Start the server
server.begin();
}
void loop() {
// Listen for incoming clients
EthernetClient client = server.available();
if (client) {
Serial.println("New client connected");
boolean currentLineIsBlank = true;
while (client.connected()) {
if (client.available()) {
char c = client.read();
Serial.write(c); // Echo data to serial monitor
// Check for end of HTTP request
if (c == '\n' && currentLineIsBlank) {
// Send HTTP response
client.println("HTTP/1.1 200 OK");
client.println("Content-Type: text/html");
client.println("Connection: close");
client.println();
client.println("<!DOCTYPE HTML>");
client.println("<html>");
client.println("<h1>Hello from Ethernet FeatherWing!</h1>");
client.println("</html>");
break;
}
if (c == '\n') {
currentLineIsBlank = true;
} else if (c != '\r') {
currentLineIsBlank = false;
}
}
}
// Give the client time to receive data
delay(1);
client.stop();
Serial.println("Client disconnected");
}
}
Step 3: Upload and Test
- Connect your Feather microcontroller to your computer via USB.
- Upload the example code to the Feather using the Arduino IDE.
- Open the Serial Monitor to view the assigned IP address.
- Access the web server by entering the IP address in a web browser.
Important Considerations and Best Practices
- Ensure the FeatherWing is securely connected to the Feather microcontroller.
- Use a reliable Ethernet cable to avoid connection issues.
- If using a static IP, ensure it does not conflict with other devices on your network.
- Avoid powering the FeatherWing from a low-capacity power source, as the W5500 module requires stable power.
Troubleshooting and FAQs
Common Issues and Solutions
Ethernet Connection Fails:
- Ensure the Ethernet cable is properly connected.
- Verify that your network settings (e.g., IP address, gateway) are correct.
- Check if your router or switch is functioning properly.
No Serial Output:
- Confirm that the Serial Monitor is set to the correct baud rate (9600 in the example).
- Ensure the Feather microcontroller is properly powered and connected to your computer.
Web Server Not Accessible:
- Verify the IP address assigned to the FeatherWing.
- Check for firewall or network restrictions that may block access.
FAQs
Q: Can I use the Ethernet FeatherWing with non-Adafruit Feather boards?
A: Yes, as long as the board supports 3.3V logic and SPI communication, it should work. However, additional configuration may be required.
Q: Does the FeatherWing support Power over Ethernet (PoE)?
A: No, the Ethernet FeatherWing does not support PoE. It must be powered through the Feather microcontroller.
Q: Can I use the FeatherWing with Arduino Uno or other non-Feather boards?
A: While designed for Feather boards, it can be used with other microcontrollers that support SPI, but additional wiring and configuration are needed.
Q: How do I update the W5500 firmware?
A: The W5500 module does not require firmware updates, as it is a hardware-based Ethernet controller.
