| 摘 要： | 手动调节多路电压输出很难实现，费时、费力，不仅操作麻烦、效率低而且精度也很低。提出了一种电压输出方法，单片机连接三片具有四路电压转换的DAC8420，通过USB与电脑通信。用VC＋＋设计电脑用户界面，电脑控制下位机可输出多达12路可调的电压信号，输出信号精度高，操作简单。

| Abstract: | It is very difficult to make the multi-channel voltage output by hand,wasteful in time and energy, troublesome operat-ing、lower effect and accuracy. A way of voltage output is proposed,a single-computer link three DAC8420s with four-channel voltage conversion and communicate with computer through USB .Designing a computer user interface by VC＋＋, computer control slave single-computer to output up to at most 12 channels adjustable voltage signal with high accuracy and simple operat-ing. |
