AT89C51SND1C是AT89C51核心的处理器，包含一个MP3解码器，完全兼容8051的Keil C51编译环境，适合8051使用者的MP3解码应用。本代码在基本代码基础上增加了LCD驱动部分，需要比较多的RAM和ROM资源，大家按照自己的系统资源情况，选择基本版本代码还是扩展LCD的代码。-AT89C51SND1C is AT89C51 core processors, includes an MP3 decoder, 8051 is fully compatible with the Keil C51 compiler environment 8051 suitable for user

本程序是PIC单片机自带AD转换功能的使用例子，并且采用了多次采样取平均值的方法进行抗干扰。-This procedure is a single-chip microcomputer PIC own use of AD conversion examples, and using a number of sampling methods to obtain the average interference.

用L298作为驱动器，控制两相混合式步进电机。 按键从上至下分别为减速，加速，正转，反转，停止。 具体参数还没有设定过。速度有些慢，加速按2下有效，然后就不能再快了。 转速输出是按照最小系统版的数码管写的。电路图里太麻烦就没画了。-Using L298 as the drive to control two-phase hybrid stepping motor. Buttons from top to bottom respectively, deceleration, acceleration, are being transferred, reverse, stop. Specific parameters have not yet been set. Some of the slow speed, speed up by 2, effectively, and then can not be faster. Speed output is in accordance with the minimum system version of the digital tube wrote. Circuit where not too much trouble drew.

系统能够产生正弦波、方波、三角波。同时还可以作为频率计测频率。函数信号的产生由MAX038和外围电路完成，能产生1Hz―20MHz的波形。-system can produce sine, square, triangle wave. Also as frequency measurement frequency. Signals generated by the MAX038 completed and the external circuit, which can produce 1Hz- 20MHz waveforms.

在AVR单片机的控制下，通过WinAVR编译器和makefile的编写，在一个数码管上实时输出键盘输入的字符，当在键盘上按下某一个键时，在数码管上显示该键的值。如按下1时数码管显示1，按下F时数码管显示F。-control, through WinAVR compiler makefile and the preparation, in a real-time digital control keyboard input output of the characters, when pressed on the keyboard a button, digital tube revealed that the value of the bond. Touching 1:00 a Digital Display, when pressed F F Digital Display.
