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: lpd6803是深圳英盛美半导体公司出品的一款高性能led驱动芯片,该芯片具有如下特点:
三路输出,恒流驱动:每路各有一个外挂电阻调整电流:Iout(max)=30mA, Vout(max)=12V。
兼容恒压模式,可直接替换ZQL9712等常规芯片。
直接PWM输出,无亮度损失,降低数据传输量,有效减少电磁干扰(EMI)。
支持32级灰度/256级灰度(内置反伽码校正逻辑)两种模式,扫描频率高(>4000HZ)。
仅需时钟线/数据线的两线传输结构,级联能力超强。
内建振荡器,支持FREE-RUN模式,降低控制电路成本。
内置LDO稳压电路,电源适应范围宽(4.8-8V),输出耐压高(LED灯供电电压可达12V)。
简化外围配套,可扩充性好,也可作为PWM发生器控制大电流器件驱动大功率LED灯。
该芯片特别适合用于led幕墙灯、led全彩点光源、广告字、异型屏等产品,相对于9712/6106/595/5026/62726等芯片来说,外围器件少,电路简单,
布线容易,使用电线节省,控制器也简单。
