摘　　要：MAX3100是一种具有SPI接口和IrDA模式的通用异步收发器,而TFDU4100则是符合IrDA 1.2标准的低功耗连续红外数据收发模块,本文利用ATmega8单片机的SPI接口与MAX3100进行双向通信,由MAX3100与TFDU4100相连接可实现高达115.2kbps的红外数据通讯,文中给出了硬件连接电路及C语言实例。MAX3100 is a general asynchronous transceiver, having function of SPI interface and IrDA pattern. TFDU4100 is a module of series infrared transceiver which conforms to the IrDA 1.2 standard. In this paper, the SPI of ATmega8 is used to communicate with MAX3100, so the infrared bit rate can reach as high as the ll5.2kbps between MAX3100 and TFDU4100. The circuit and the C language example is shown in this paper.
