基于单片机的八路数字电压表

8路数字电压表可以测量0~5V范围内的8路输入电压植，并能在4位LED数码管上轮流显示。测量最大分辨率为0.01V，绝对测量误差约为±0.02V-SCM-based eight-way digital voltage meter 8-channel digital voltage meter can measure the range of 0 ~ 5V input voltage within the 8-sik, and can last four rotating LED digital tube display. Measured maximum resolution of 0.01V, the absolute measurement error is about ± 0.02V
