单片机的坐标128x64液晶KS0108驱动程序(C51编写）-MCU coordinates KS0108 128x64 LCD Driver (C51 preparation)

c8051f020单片机串行通信口UART0使用-C8051F020 single-chip serial communication port UART0 to use

基于单片机的波形发生器，可产生方波，三角波及正弦波，频率可调。-Based on single-chip waveform generator to generate square wave, sine wave triangle spread, frequency adjustable.

用51单片机控制硬盘读写，并用通过液晶界面显示。-SCM control with 51 hard drives to read and write, and use the LCD interface display.

串口通讯经典使用程序4,以前收集整理的东东,希望对大家有用!-Serial Communication Classic to use the program 4, previously collected Dongdong finishing the hope for all of us!

采用UART方式0与LM74通信。 用C8051f020的P0.7作片选，主机通过TXD发送时钟信号，实现同步通信,半双工.RXD 作双向数据线.用六位数码管显示LM74采集的温度值-The use of UART communication mode 0 and LM74. P0.7 used for the C8051F020 chip select, host TXD sent through the clock signal, to achieve synchronous communication, half-duplex. RXD for bi-directional data line. With six digital tube display LM74 temperature collected

对利用595串行实现IO口扩展，本程序仅用3个IO口扩展到6个数码管-Realize the use of 595 serial IO port expansion, this procedure only 3 IO I extend to six digital tube

USB转串口程序，已经调试通过，调试环境为keilc.-USB to serial procedures, has been through the debugging, debugging environment keilc.
