EMAC driver for the ENC28J60 Ethernet controller
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:
- 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; } ...
