改程序通过使用8254和8255以及其他一些辅助芯片实现了一个简单但功能比较完善的电子钟...

FAT16 磁盘格式引导程序(ASM)-FAT16 disk format guide (ASM)

实现高级电子琴的程序，并实现若干扩展功能。 基本功能：用8257键盘输入对应的七个音阶，通过实验箱的喇叭发出声音，并通过七段数码管显示输入音阶； 扩展功能：1、录音：记录所弹奏曲目 2、放录音：任意时刻重放最新记录曲目 3、在程序中可预设一曲目，按一键实现播放该曲目。 4、在播放录制曲目或预设曲目时，按8279键盘上任意键可以暂停播放，再按一次从暂停处继续播放。 5、程序运行时有友好的用户介面 -Realize high-level organ of the process and realize a number of extensions. Basic functions: keyboard 8257 corresponds with the seven scale, through experimental sound speaker boxes, and through Seven-Segment LED display input scale the expansion of functions: one, sound recording: Record the playing pieces 2, released recordings: any time replay music 3-to-date records, in the proceedings may be the default one track, according to realize one key to play the tracks. 4, recording tracks in the player or the default program, press any key on the keyboard 8279 can pause playback, press once again to continue from the suspended players. 5, is running friendly user interface

该程序时是用12864液晶显示4*4矩阵键盘的按键值的，键盘按键值采用啄行扫描法扫描按键值。将按键值返回单片机，再通过12864液晶字符显示显示出来

装置的功能是对温度进行实时监测与控制。由温度传感器DS18B20对温度进行采样和转换成数字信号送入单片机，并与设定的报警温度上、下限值进行比较，信息通过LCD显示出来。如实时温度超过设定的上、下限值，一方面由LCD显示信息，并发出警报声；另一方面自动控制继电器（Relay）开接通或断开，从而控制加热源的开与断，达到对温度进行实时控制的目的。-Device" s function is real-time temperature monitoring and control. Temperature by the temperature sensor DS18B20 sample and converted into a digital signal into the microcontroller, and with the set alarm temperature of the upper and lower limit comparison information through the LCD display. Such as real-time temperature exceeds a set upper and lower limits on the one hand by the LCD to display information, and the alarm sound the other hand, automatic control relay (Relay) to open turn on or off to control the opening and the heat source off, to achieve real-time temperature control.
