这是一个简的电子屏幕，用于小型车间，能显示年，月，日。计划产量，实际产量都可以显示在板上。我用protus实现硬件仿真，并最终有实际成品出来。-This is a simple electronic screen for the small workshop, to show the year, month, day. Program output, actual output can be displayed on the board. I realize protus hardware simulation, and ultimately have the actual finished product out.

自制MP3硬盘播放器，含电路图（DDB）以，源代码及使用说明-Self-made hard drive MP3 players, including circuit diagrams (DDB) to, source code and use

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
