用I/O口实现电池电压线性检测

Using I/O Interface to Realize Linear Test of Battery Voltage

利用PIC16C6 2单片机的I/O接口和定时捕捉功能 ,来获取比较器产生电位跳变的时间 ;通过对RC充电特性曲线的计算 ,实现A/D转换。

We used I/O interface of PIC16C62 microcoufuoller and its function of time catching to obtain the time of voltage jumping of the comparer.Through the calculation of RC charge particularity curve ,the A/D exchange was realized .
