Description: 本点阵电子显示屏系统以STC89C52单片机作为控制核心,其外围电路包括存储器扩展模块、LED显示电路模块、驱动电路模块、PC通信电路模块。其中,控制芯片的行驱动用2个74LS138构成4-16译码器,采用1/16扫描方式。列驱动采用74HC595驱动,一个汉字用2个74HC595控制。系统同时扩展了SRAM芯片6116和Flash ROM 29C020芯片, 系统控制过程中,可以满足大容量字模的运算,采用Flash ROM进行汉字掉电保护,通过单片机修改显示内容。并详细介绍了在硬件和软件上的实现过程。 本设计中第二章讲述系统方案的设计与分析;第三章讲述LED点阵显示系统的核心硬件设计,主要包括控制芯片、显示电路和驱动电路的设计等;第四章详细介绍了系统核心软件——静态显示程序的设计过程,之后以左移显示程序为例介绍动态显示程序的设计以及主程序的设计;第五章对PC通信协议及软硬件设计予以详细介绍。 如需详细的硬件电路及说明,可以与作者联系!-err

Description: 项目名称:测量放大器 压缩包里面含有设计测量放大器的c源程序(开发环境为keil),目标代码(可直接烧入AT89S52芯片运行),电路原理图等。 源程序含有软件模块:4×4矩阵键盘扫描,led显示,可编程信号衰减。 硬件模块:采用医学生理信号检测仪器的前置放大器的结构,可放大极其微弱信号,譬如毫伏级心电信号。在此基础上加入可编程衰减器。 实现功能:通过按键输入微弱信号的放大倍数,可以相应放大微弱信号。设置倍数时,有四个LED显示倍数,按“千”,“百”“十”,“个”顺序设置,待设置的位会闪烁等待设置。放大倍数为1~1000倍。,譬如可以把1mv的微弱电压放大至1v,误差小于0.3%。用到的芯片有at89s52,ADC7520,opa177,74ls245,74ls138等。纯属原创。
