I'm trying to compile the example code for the Arduino Ethernet shield on my new Illuminato, and I'm getting this error:

error: 'byte' does not name a type In function 'void setup()':

The example code is from the playground;

Code:

#include <Ethernet.h>

byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
byte ip[] = { 10, 0, 0, 177 };
byte server[] = { 64, 233, 187, 99 }; // Google

Client client(server, 80);

void setup()
{
  Ethernet.begin(mac, ip);
  Serial.begin(9600);

  delay(1000);

  Serial.println("connecting...");

  if (client.connect()) {
    Serial.println("connected");
    client.println("GET /search?q=arduino HTTP/1.0");
    client.println();
  } else {
    Serial.println("connection failed");
  }
}

void loop()
{
  if (client.available()) {
    char c = client.read();
    Serial.print(c);
  }

  if (!client.connected()) {
    Serial.println();
    Serial.println("disconnecting.");
    client.stop();
    for(;;)
      ;
  }
}

The highlighted line is byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };

I'm assuming something is borked in the Illuminato core files, since it will compile fine if I select another board than the Illuminato. Unfortunately, I have only a vague idea what the "core files" actually do, and I'm way out of my league to debug this. The liquidware guys seem to be otherwise engaged, so I'm hoping to find some insight here! I'd really like to be able to play with my Ethernet shield!

Thanks for your help!

above the #include, try throwing in:

Code:

#define byte uint8_t

or just change all the byte's to uint8_t

[Reply #2 on:]

I'll prosume the previous poster ment:

Code:

#define uint8_t byte

or

Code:

#define unsigned char byte

?

Thank you for the responses! Unfortunately, this solved the issue in the scope of my sketch, but uncovered many more compile errors. I'll post them here, but would not be surprised if I just need to sit on my hands and wait for updated core files  :-[

@acleone Thanks, this worked!   I tried AlphaBeta's response first, and never tried yours until now.

Compiles just fine. Can you give me some deeper insight into what is going on here behind the scenes? Should this define statement exist somewhere in the Illuminato core files, such that I can add it myself and avoid this particular gotcha?
