摘要
DMF-50840 点阵图形液晶显示由大屏幕 LCD 液晶显示器、SED1335 控制器、CCFL 背光逆变器和 DC-DC显示驱动电源组成。基于 C8051F020 单片机控制的液晶显示屏 SED1335 控制器,解译 MPU 发来的指令代码,将参数置入相应寄存器内,并触发相应逻辑电路运行。软件设计采用配置 C8051F020 单片机为无块选择的分片模式 8 位驱动。
DMF-50840 Liquid-crystal display (LCD) consists of bigger display, SED1335 controller, CCFL backlighting invert device and DC-DC driving power supply. The instruction code sent by MPU is encoded and the parameter is placed into the register and the logic electric circuit is triggered to run by using SED1335 controller of LCD based on C8051F020 Microcontroller. In software design, C8051F020 MPU is configured into 8-bit mode drive to have no piece of choices.
