基于PIC18F2550的OLED测试系统的设计与实现
Design and Implementation of OLED Test System Based on PIC18F2550
摘要
针对AM-OLED的结构与特点, 提出了一种以PIC18LF2550为主控器、以SVGA050微显芯片为对象的OLED接口电路设计方案, 通过主控器的I2C串行总线配置各模块的寄存器参数, 可以将VGA和CVBS格式的视频输入信息在OLED上正确显示出来。通过对开发的硬件系统进行实测, 验证了该方案的有效性。
Abstract
Based on the structures and characteristics of AM-OLED, a design program of AM-OLED interface circuit for SVGA050 microdisplay chip is presented using PIC18LF2550-based controller. By the master of the I2C serial bus configuration registers of each module parameters, VGA and CVBS video input information is correctly displayed on the AM-OLED. The development of the hardware system measurement verified the effectiveness of the program.
