基于PSoC的数字电压表设计

The design of digital voltmeter based on PSoC

采用Cypress公司生产的PSoC3芯片实现了一个数字电压表的设计。设计使用芯片集成的A/D转换模块完成模数转换,并且通过程序调用读取相应的数字量及芯片强大的LCD显示模块,将转换后的数字量和相应的模拟量显示出来。本设计具有硬件设计简单、软件设计图形化、可以充分利用PSoC提供的固件元件的优点。

The digital voltmeter is implemented by using PSoC3 chip of Cypress. The analog-to-digital conversion is realized by chip integrated A/D converter module, and the corresponding digital value is read by the procedure call. Using chip powerful LCD display module, the converted digital quantity and the corresponding analog are displayed. The design has advantages of simple hardware design, graphical software designs, and making full use of the embedded firmware components from PSoC.
