我用单片机8952和电压比较器339做了一个简单的电容容量测量表，参数大
致如下：
电容测量范围为1pF-9999.99uF，最小分辨力为1pF。分为5个量程，可以自
动切换量程，也可手动切换。
另外，有简单的频率计功能，能测量0-60MHz的数字信号频率（TTL电平）；
还可以产生几个单点频率的方波信号（比如1KHz）。
采用1602LCD作为显示器；4个按键控制；使用24C01保存当前设置值，不用
每次开机重新设置。可单5V供电，也可9V交流供电
-I used the single-chip 8952 and the voltage comparator 339 to do a simple capacitance measurement table, parameters are as follows: capacitance measurement range 1pF-9999.99uF, the minimum resolution for the 1pF. Divided into five ranges, you can automatically switch range can also be manually switched. In addition, a simple frequency meter function, capable of measuring 0-60MHz frequency digital signal (TTL level) can also lead to several single-point-frequency square-wave signal (for example, 1KHz). 1602LCD used as a monitor 4 button control use 24C01 to preserve the current settings, do not reset each boot. Can be a single 5V power supply, 9V AC power supply can also be
