TMS320C31与MAX125 A/D转换器的接口设计及应用

Interface Design between TMS320C31 and MAX125 A/D Converter

在描述MAX12 5A/D转换器的特点及工作原理的基础上 ,结合在静电悬浮控制系统中的应用 ,从硬件方面介绍了该芯片与TMS3 2 0C3 1的接口设计方法 ,并给出了数据采集过程采用定时中断方式的编程示例。

Features and operating principle of MAX125 A/D converter are described firstly. A practical interface between TMS320C31 and MAX125 is introduced for an electrostatic suspension application. The sample code based on TMS320C31 is also presented to realize data acquisition by using timer interrupt mode.
