使用红外线通信的MCP2120

The MCP2120 is a cost effective and easy to use
device for sending and receiving IR serial data. The
MCP2120 encodes an asynchronous serial data
stream, converting each data bit to the corresponding
Infrared (IR) formatted pulse. IR pulses that are
received are decoded into the corresponding UART
formatted serial data. The MCP2120 may be used to
