以Silicon Laboratories公司C8051F230单片机为控制核心，采用16路动态扫描方式进行显示的LED大屏幕显示系统的设计方案。采用大功率三极管TIP127进行行驱动，提高了亮度。单片机通过读取外部总线数据，可实现与上位机协同工作，也可以脱离上位机独立工作。高速的单片机系统可显示图象、文字、数字等多种内容，并且通过优化算法实现了上下左右移动，以及百叶窗等特殊效果。-To Silicon Laboratories, C8051F230 microcontroller to control the core, using 16-way dynamic scan mode to display the LED large screen display system design. Carried out using high-power transistor TIP127 line drive to improve the brightness. MCU by reading the external bus data can be realized with the host computer to work, you can also work independently from the host computer. High-speed microcontroller system can display images, text, numbers, and other content, and by optimizing the algorithm of the up and down and move around, as well as blinds and other special effects.

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
