摘　　要：I2 CBUS(InterIntegratedCircuitBUS内部集成电路总线 )是由Philips公司推出的二线制串行扩展总线 .I2 C总线是具备总线仲裁和高低速设备同步等功能的高性能多主机总线 .利用 5 1单片机的两根普通的I/O线 ,模拟I2 C总线从器件给出源程序 .这些程序都在已研制的CDMA直放机监控模块的I2 C总线接口中获得验证和通过 .I 2C bus (internal integrated-circuit bus) as a bus of high performance is a serial extended bus of two-wire system presented to public by Philips Co.. It is a bus for multiple master computers with bus arbitration and high or low speed synchronization. The authors present here the method of simulating a slave device with I 2C bus by using two common I/O wires of Model 51 single-chip microcomputer. These programs have been validated at the interface of I 2C bus in the watch module of CDMA direct amplifier developed by the authors.
