本代码为Jennic公司芯片JN5121 电池电压测量测试程序

A/D模块，压力测量系统设计。采用PIC16F877单片机，此型号有8路A/D转换通道，可将压力传感器输出的1--5V的电压信号转换为压力数值，并通过串口发送到上位机，通过串口调试助手即可查看数据。-A/D module, the pressure measurement system design. The use of PIC16F877 microcontroller, this model has eight A/D converter channel, the pressure sen

软件A/D所能实现的精度有限，测量电压范围是2-15V-Software A/D can achieve the accuracy of the limited voltage range of measurement is 2-15V

基于51单片机的电压测量，这是我暑假编的，已经经过我的调试了，是可用可行的-Based on 51 single-chip voltage measurement, this is my summer series, after debugging, are available and feasible
