摘　　要：在此详细介绍了如何使用Lab VIEW调用Win IO来控制博来科技股份有限公司的单片机主板2I260A的DIO(数字输入/输出),以及通过控制2I260A的DO来实现控制放大器电路模块中继电器的切换,从而达到编程调节放大器增益的目的。试验结果表明,这是一种比基于底层I/O端口控制更直接更高效的控制方法,完全可以满足放大器增益档位控制的要求,不仅提高设备整体的利用率、降低开发周期,而且效果良好且运行稳定。The method how to use LabVIEW to call WinIO to control DIO（digital input output）of microcontroller main？board 2I260A made by LEX Computech Co.,Ltd is described in detail. The switching of relay in control amplifier circuit module is realized by controlling DO of 2I260A to achieve the purpose of the amplifier gain adjustment. The experimental results show that this control method is more direct and more efficient than the control method based on the underlying I/O port,and can ful？ly meet the requirements of the amplifier gain control. It improved the overall equipment utilization and reduced the development cycle.
