收集了不少人的pid 资料，整理后的代码

我在使用陈明计先生写的small RTOS和51单片机做过几个小项目，起初都很好，开发变的容易了，程序变的容易修改。后来随着任务个数的增多，RAM很快就不够用了。51系列的芯片内部RAM普遍都是256个,很难找出1024个字节RAM或更多，而价格又合适的。记得上一次我没有办法被迫使用了64K flash内部带768字节的XRAM的51芯片，而我根本用不到那么多flash。-I use Mr. Chen Mingji written small RTOS and 51 MCU done several small projects at first were very good to develop easy to change the program become easier to modify. Subsequently, the increase in the number of tasks, RAM is not fast enough. 51 series of chip RAM are generally 256, it is difficult to find 1024 bytes of RAM or more, while prices will be appropriate. I remember the last time I had no way forced to use a 64K flash with 768 bytes of internal XRAM of 51 chips, and I will never use that much flash.

基于ARM7 7x256芯片的USB通信实现, 编译器IAR4.X以上版本.-Chips based on ARM7 7x256 realize USB communication, the compiler IAR4.X above.

显示模块的程序，有数码管显示功能和按键功能，灯的功能，能方便的大家学习数码管。当数码管特定的段加上电压后，这些特定的段就会发亮，以形成我们眼睛看到的字样了。如：显示一个“2”字，那么应当是a亮b亮g亮e亮d亮f不亮c不亮dp不亮。LED数码管有一般亮和超亮等不同之分，也有0.5寸、1寸等不同的尺寸。小尺寸数码管的显示笔画常用一个发光二极管组成，而大尺寸的数码管由二个或多个发光二极管组成，一般情况下，单个发光二极管的管压降为1.8V左右，电流不超过30mA。发光二极管的阳极连接到一起连接到电源正极的称为共阳数码管，发光二极管的阴极连接到一起连接到电源负极的称为共阴数码管。常用LED数码管显示的数字和字符是0、1、2、3、4、5、6、7、8、9、A、B、C、D、E、F。
