I'm working on a http server using a LPC2129 and a Microchip ENC28J60. It's already functional using the Microchip TCP stack adapted to LPC. Now I'm trying to use the RL-TCPnet and I need to write the ENC28J60 Driver. I'm using the LAN91C111 as base to write the driver. Maybe someone can help me with some tips to how to write the functions, because the controllers are quite different.
