一种很好的键盘键扫描方法，对初学者有大大的帮助。

使用微芯公司的PIC8F458单片机，用C语言实现B口电平变化中断程序，并且在中断中用C实现步进电机的驱动程序。-The use of Microchip

触摸屏设计开发详细资料以及参看设计电路板图-Touch-screen design and development of detailed information and refer to design the circuit board diagram

二极管闪动实验，C51制作-diodes flashing experiment, the production C51

LCD Driver to AVR. Tested on ATMEGA 16.

这是LCD1602与msp430之间的通信,其实可以直接从51移植过来,但是一定要在硬件加上拉电阻,要不然是不通不过的,我说的是你用的是5V的LCD-This is the LCD1602 and communication between the MSP430 can in fact be a direct transplant from the 51, but must be coupled with pull-up resistor in the hardware, otherwise it is unreasonable, however, I say is that you use the LCD is 5V

非常好用的CH375串口转USB口程序.可以方便的实现,用USB通讯,和做为主机- code usb

这是一个c8051F020单片机通讯程序，请各位大侠，看了后多提宝贵意见。-C8051F020

在51单片机下44780液晶显示块的编程实例。-Under 44,780 in the 51 single-chip LCD block programming examples.

这是一个tcp 的client 源程序,可以在单片机测试时使用.-This is a tcp source code of the client, you can use single-chip processor.

这是从网上找来的一个比较典型的PID处理程序，在使用单片机作为控制cpu时，请稍作简化，具体的PID 参数必须由具体对象通过实验确定。-It is found from the Internet a more typical PID process, as a control in the use of single-chip cpu, please make some simplification, the specific parameters of the PID must be determined through experiments at specific audiences.
