ESP8266 LWIP driver for ENC28J60 ethernet module

espenc

This is a (relatively) proper implementation of enc28j60 driver for LWIP on ESP8266.

Both receive and transmit works properly now, but it hasn't been tested much yet. Code needs some major refactoring.

Usage

1. Copy or symlink driver/espenc.c, driver/espenc.h, driver/spi.c, driver/spi_register.h and driver/spi.h somewhere to your project.
2. Add espenc_init() in your user_init()
3. Connect ENC28J60 to ESP's SPI, connect INT pin to GPIO5 (or change it for anything you like in driver/spi.h.
4. PROFIT.

TODO

• Move any framework specific code to separate headers
• Port & test on esp8266-arduino
• Port & test on Sming
• Check latency (70ms?!)
• Make it a little bit more stable
• Support for hardware RESET
• Does not work when wifi mode is set to NULL_MODE
