&par Example Description

This example describes how to use ethernet PHY by using DAL library.
After configured ethernet mainboard will be use USART1 to printf static IP address.
if computer ping static IP address 192.168.1.100,  computer will be visit mainboard normality.

    - static IP address : 192.168.1.100
    - Network mask      : 255.255.255.0
    - Gateway           : 192.168.1.1

&par Hardware Description

    - ETH RMII pin configuration
    ETH MDC      ----> PC1
    ETH MDIO     ----> PA2
    ETH REF CLK  ----> PA1
    ETH CRS DV   ----> PA7
    ETH RXD0     ----> PC4
    ETH RXD1     ----> PC5
    ETH TX EN    ----> PG11
    ETH TXD0     ----> PG13
    ETH TXD1     ----> PG14

    PHY RESET    ----> PD11(option)

The USART1 is configured as follows:
    - TX:PA9, RX:PA10
    - BaudRate = 115200 baud
    - Word Length = 8 Bits
    - One Stop Bit
    - No parity
    - Hardware flow control disabled (RTS and CTS signals)
    - Receive and transmit enabled
