MSP430与I2C总线接口技术设计方案
分享资料个
分析了MSP430 单片机I/O 端口的结构特点，提出了适合MSP430 特点的I2C 总线接口
方案。该方案优化了接口方法，降低了代码量。结合实际给出了与常用I2C 器件AT24C02
的接口方法实例，并进一步论述了MSP430 与温度传感器LM92 的接口方法。通过实验证明，该方案硬件结构简单，程序代码量小，是MSP430 与I2C 总线接口的实用方法。
The structural features of MSP430's I/O port are analyzed in the paper.
Based on these analyses, an optimal interface method is worked out and described
in the paper. This method could cut down the codes size and simplify the structure
of software and hardware. The further details of the method are presented in an
application, in which AT2402 and LM92 are involved. The experiments indicate that
it is a practical way to realize interface between MSP430 MPU and I2C bus components.
