EMAC driver for the ENC28J60 Ethernet controller

https://os.mbed.com/media/uploads/hudakz/enc28j60_module01.jpg

This is a fork (the INT and RST pins are not used) of the ENC28J60-EMAC driver published by Tobias Jaster at

https://github.com/tobiasjaster/ENC28J60-EMAC-Driver

Usage:

  • Connect the ENC28J60 module to the Mbed board as follows:

https://os.mbed.com/media/uploads/hudakz/enc28j60-emac.png

  • Import (add) this ENC28J60-EMAC library to your program.
  • Add a "mbed_app.json" file with the following content to the root directory of your program:

    {
        "target_overrides": {
            "*": {
                "platform.callback-nontrivial": true,
                "enc28j60-emac.mosi":  "D11",
                "enc28j60-emac.miso":  "D12",
                "enc28j60-emac.sck" :  "D13",
                "enc28j60-emac.cs"  :  "D10"
            }
        }
    }
  • Replace "D11", ..., "D10" with the actual pin names you selected on the Mbed board to be used for the SPI communication.
  • To set the MAC address define an array with the desired address bytes and call the "set_hwaddr(mac)" function before calling the network interface "connect" function.

For example:

    const uint8_t       MAC[6] = { 0, 1, 2, 3, 4, 5 };
    EthernetInterface   net;
 
    int main()
    {
        net.get_emac().set_hwaddr(MAC);             // set MAC address
        if (net.connect() != 0) {
            printf("Error: Unable to connect to the network.\n");
            return -1;
        }
     ...
