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

ACEXT1K30最小系统的原理图和成熟PCB版图，可以直接拿到PCB制作厂商制作。同时也提供了与你自己定义的系统的接口，方便你将ACEXT1K30直接嵌入到你的系统中，而不需要再做其他的工作了-ACEXT1K30 the schematic and PCB layout mature, can be submitted directly to the production of PCB manufacturers produced. Also provided with your own definition of the interface, you will facilitate ACEXT1K30 directly embedded into your system without the need to do the work of the other
