Atmega系列单片机 BootLoader程序

AT24C64 Keil C 代码-AT24C64 Keil C code

本程序用于把串口助手所写内容通过pc发送给单片机，并且由单片机把所写内容发送到lcd上面进行显示，所用单片机为日立系列h83664十六位单片机，实验证明可以准确显示pc上面所写的内容。里面包含各个写lcd的子程-This procedure for the serial written by aides through the pc sent to the microcontroller, and written by Singlechip the above content is sent to the lcd display, single-chip microcomputer used for the Hitachi series h83664 16 microcontroller, Experiments show pc can accurately display the contents of the above written. Which contains a subset of the various write-way lcd

C51 用PCA 模拟串口，很有参考价值得源码-C51 with PCA serial analog, a valuable source

[Note : AT89x51 use 12M or 11.0592M crystal, the measured use 11.0592M] [Keil uV2 7.01 compiler running through the procedure done keyboard data parity]

LCD1602的驱动代码（头文件） 用mega16单片机实现-LCD1602 driven code (the first) with mega16 MCU

本原程序基于8051F020,目的是掌握点阵液晶显示器的原理，电路设计及编程方法-Based on the primitive procedures 8051F020, aim is to grasp the principle of dot-matrix liquid crystal displays, circuit design and programming method

将键盘发回的数据放到一个缓冲区里（数组），当按键结束后发生内部中断来处理所按的按键-returned to the keyboard data in a buffer (the array), when the button after internal interruption to processing by the key

实现键盘码的读取，并在LED上显示。单片机部分，并在KEIL下运行-? 殚 ???? ???????邋 ?LED 邋 ???? ??机 ??殚 ????邋 ?KEIL 邋 | |
