4x4键盘的程序，新思路，希望能对大家有所帮助。-4x4 keyboard procedures, new ideas, hoping to be helpful for everyone.

为ascii码转换程序，自己编写的，可以使用masm工具编译。-Ascii code for the conversion process, I have written, you can use the MASM compiler tools.

单片机用T1中断在IO口P1.0输出乐曲(在P1.0口与VCC间接一喇叭即可听到) 1.由于输出的是方波，比较难听:-)你也可以将波形细分用DA输出正弦波 2.由于T1频繁中断，任何其他中断发生都会是乐曲打顿，只适合试验 3.优化音符编码：一个字节中包含节拍、音符、升降调，可区分数据和命令 -Single-chip microcomputer used in the IO port T1 interrupt output music P1.0 (P1.0 port with VCC in the indirect one can hear the speaker) 1. As the output is a square wave, more bluntly :-) You can also fine-waveform DA output sine wave with sub-2. Due to the frequent interruption of T1, any other interruption occurs Dayton will be playing music, is only suitable for test 3. optimized coding notes: A byte contains rhythms, notes, take-off and landing tune can distinguish between data and command

基于avr,D12的U盘设计,有完整的USB1.1的协议代码.-Based on the avr, D12 U-disk design, have complete agreement USB1.1 code.

AVR单片机M16L绝对可以用的4*4键盘程序,附连接图.-AVR Singlechip M16L can definitely use 4* 4 keyboard procedures, attached connection diagram.

这是我自已写的HD44780 LCD1602液晶屏的程序，是基于AVR单片机上实现的。 /************************************************************************************************** * 简介 * * 本模块仅使用于字符显示液晶模块 * * 当前版本的驱动仅支持以下类型LCD模块驱动: * Hitachi HD44780 或与之兼容的芯片. * * LCD显示函数支持以下格式: * 1 line x 16 characters 2 lines x 16 characters 4 lines x 16 characters * 1 line x 20 characters 2 lines x 20 characters 4 lines x 20 characters * 1 line x 24 characters 2 lines x 24 characters * 1 line x 40 characters 2 lines x 40 characters *说明： * 1 line x 16 characters 需要定义为2*8的液晶模块 * * 不支持外部内存模式 **************************************************************************************************/ -This is my own written HD44780 LCD1602 LCD procedure is based on the AVR Single Chip achievable. /*************************************************************************************************** Introduction** This module uses only the characters displayed in the LCD module** the current version of the driver

工程师在用Keil开发程序时，在代码性能要求较高的场合，需要对代码段的执行时间作统计。比如在做LED显示屏软件扫描程序，或一些定时采集数据程序，如果在软件仿真的时候就能够清晰知道代码段的运行时间，那就可以对程序进行优化，或者插入汇编代码(asm)达到最高运行速度。 关键字:Keil DLL C语言 ASM 汇编-engineers in the development process with Keil, the code performance requirements higher occasions, need to block the execution time statistics. For example, in the software do LED scanning procedures, or some regular data collection procedures, If the software simulation time can understand clearly code of the running time, it can process optimization, or insert code compilation (asm2) to achieve maximum speed. Keywords : Keil DLL C language compilation ASM
