调试通过了的基于89S51的1602液晶显示的程序-Debug adopted 89S51-based liquid crystal display of the 1602 procedure

BASM_for_Beginners.是DELPHI开发工具嵌入汇编语言,介绍了两种语言的接口,其使用语法-BASM_for_Beginners. Yes DELPHI embedded assembly language development tools, the introduction of the interface in two languages, the use of grammar

PWM 控制 LED 灯渐亮渐灭程序 适用 ME300B 开发系统 利用定时器控制产生占空比可变的 PWM 波 按K1，PWM值增加，则占空比减小,LED 灯渐暗。 按K2，PWM值减小，则占空比增加,LED 灯渐亮。 当PWM值增加到最大值或减小到最小值时，蜂鸣器将报警。-PWM control of LED lights getting brighter gradually eliminate procedures apply ME300B development system the use of timer control which produces a variable duty cycle PWM wave by K1, PWM value is increased, then the duty cycle decreases, LED lights dimming. According to K2, PWM value is reduced, then the duty cycle increases, LED lights gradually brighter. When the PWM value is increased to maximum or reduced to minimum, the buzzer will alarm.

This a assembly languages that teach how to write floppy disk subroutine. A great start for beginner who want to learn how ASM work. i got 100 for this assignment. have a look and comment-This is a assembly languages that teach how to write floppy disk subroutine.

此程序为KEIL环境下开发的代码（开发环境备选里没有KEIL），功能在成功运行后可以播放“生日快乐”歌。所需要的开发硬件为AT89C51为主芯片的单片机。-This program is developed under the code in KEIL environment (development environment, where there is no alternative KEIL), features a successful running play " Happy Birthday" song. Required the development of hardware-based chip microcontroller AT89C51.
