用本文所描述的电路设计,任何8051微控制器派生产品都可以 用IrDA(Infrared Data Associa-tion,红外数据协会)所确定的串行红外(SIR)格式通信。通信是一个两级过程,首先微控制器经一个“位控制”(“bit-banged”)SPI串行接口向UART(IC1)发送信息,然后UART以IrDA方式对信息格式化。
With the circuit design described in this document, any 8051 microcontroller derivative can communicate in serial infrared (SIR) format as determined by the Infrared Data Association (IrDA). Communication is a two-stage process. First, the microcontroller sends a message to the UART (IC1) via a “bit-banged” SPI serial interface. The UART then formats the message in IrDA.
