MAC Module (Microchip ENC28J60) for Microchip TCP/IP Stack — File: ENC28J60.c // Since the ENC28J60 doesn't support auto-negotiation, full-duplex mode is // not compatible with most switches/routers. If a dedicated network is used // where the duplex of the remote node can be manually configured, you may // change this configuration. Otherwise, half duplex should always be used. //#define HALF_DUPLEX #define FULL_DUPLEX Works with WRT55AG //#define LEDB_DUPLEX

Setup Mode: Open Terminal application, and configure the serial port connected to the Explorer 16 board: • 19200 bps, • 8 data bits, 1 STOP bit and no parity • no flow control Apply power to the board while holding the S4 switch, or press and hold both the RESET and S4 switches; then, release the RESET switch. The LCD display shows the message on LCD: MCHPStack v2.0
