Introduction
- This project aims to develop an Ethernet Module, to be used in conjunction with a 8/16 bits embedded system such as the dsPic33F development board.
- The entire Ethernet Module consists of:

- Base on FreeRTOS and dsPIC33 platform
- Using POSIX-like API:
- int dmfe_open(int flags): initialize the Ethernet controller for 10MHz Half-Duplex
- int dmfe_close(): turn off the PHY layer
- int dmfe_read(void): copy a packet to the default buffer
- int dmfe_write(unsigned char device, unsigned char *buf, int count): copy count bytes of the data from buf and transmit
- void dmfe_interrupt(void): process the transmit interrupt from DM9000A
