The LAN8720A/LAN8720Ai is a low-power 10BASE-T/100BASE-TX physical layer (PHY) transceiver with variable I/O voltage that is compliant with the IEEE 802.3-2005 standards.The LAN8720A/LAN8720Ai supports communication with an Ethernet MAC via a standard RMII interface. It contains a full-duplex 10-BASE-T/100BASE-TX transceiver and supports 10Mbps (10BASE-T) and 100Mbps (100BASE-TX) operation. The LAN8720A/LAN8720Ai implements auto-negotiation to automatically determine the best possible speed and duplex mode of operation. HP Auto-MDIX support allows the use of direct connect or cross-over LAN cables.
LibDriver LAN8720 is the full function driver of LAN8720 launched by LibDriver.LibDriver LAN8720 provides basic configuration, auto negotiation and other functions. LibDriver is MISRA compliant.
/src includes LibDriver LAN8720 source files.
/interface includes LibDriver LAN8720 SMI, RMII platform independent template.
/test includes LibDriver LAN8720 driver test code and this code can test the chip necessary function simply.
/example includes LibDriver LAN8720 sample code.

Reference /interface SMI, RMII platform independent template and finish your platform SMI, RMII driver.
Add the /src directory, the interface driver for your platform, and your own drivers to your project, if you want to use the default example drivers, add the /example directory to your project.
You can refer to the examples in the /example directory to complete your own driver. If you want to use the default programming examples, here's how to use them.
