工业仪表常用到4-20mA输出此程序通过C51单片机模拟输出PWM 提供了很好的思路和事例-Industrial instrumentation commonly used to 4-20mA output of this program through the C51 single-chip analog output PWM provides a good example of ideas and

STC12C5A60S2 具备一般51单片机不可企及的高性能，有片内ADDA，速度是一般51的8倍！-STC12C5A60S2 high speed,low price, with ADDA in chip!

在做项目（工程）的时候，我们经常要用到比较多的按键，而且IO 资源紧张， 于是我们就想方设法地在别的模块中节省IO 口，好不容易挤出一两个IO 口，却 发现仍然不够用，实在没办法了就添加一个IC 来扫键。一个IC 虽然价格不高， 但对于大批量生产而且产品利润低的厂家来说，这是一笔不菲的开支! 那，我们能不能想到比较好的扫键方法：用最少的IO 口，扫最多的键？可以吗？-Doing the project (engineering), we often use the relatively large number of keys, and the IO resource constraints, so we are trying to save in another module IO ports, finally out of one or two IO ports, only to find is still not enough there is really no other way to add an IC to sweep on the keys. Although the price of an IC is not high, but low profits, high-volume production and product manufacturers, this is spending a lot of money! That, we can not think of a better scan key method: with a minimum of IO ports, scan Most of the keys? OK?

MSP430 PS/2键盘接口程序 LCD1602显示。 程序包含对PS/2键盘发送数据的处理，以及如何通过查找表显示所收到的数据，并通过显示缓存显示到1602液晶上。-MSP430 PS/2 keyboard interface program LCD1602 display. Process consists of PS/2 keyboard to send data treatment, as well as how to find table shows the data received and, through the display buffer on the LCD display to 1602.

该模拟器是在Keil7.0中使用。 只要把Ex02Dll.dll复制到 X:KeilC51BIN目录下。 打开测试程序，编译运行即可看到如图led.jpg中所显示的效果。-The simulator is used in Keil7.0. As long as Ex02Dll.dll copied to the X : Keil C51 BIN directory. Open test procedure, compile operation can be seen in figure led.jpg reflected by the results.
