基于C8051F020单片机的双接口OLED控制器设计与实现

摘要
文中提出一种基于C8051F020单片机的双接口OLED控制器的设计与实现方案。该设计以C8051F020为核心控制单元,带有两个OLED接口的印刷电路板。在写命令函数和写数据函数中调用判忙函数,保证驱动芯片在不忙状态下接收控制指令。合理排列片选、写使能、并行数据等信号的发送顺序,满足地址/数据的建立时间和保持时间。实验结果证明两块OLED可以准确显示预留信息,具有亮度高、响应速度快、可视角宽的优点。该方案效果理想,双接口功能进一步扩展了实用性,可移植于相关仪器仪表的显示终端。
A design and implementation scheme of the dual-interface OLED controller based on the C8051 F020 single chip microcomputer(SCM)is proposed. A printed circuit board with two OLED interfaces is designed taking the C8051 F020 as the core control unit. The busy judgment function is called during the writing process of the command function and data function,so as to ensure that the drive chip can receive control instructions when it is not busy. The transmission sequence of signals like chip selection,write enabling,parallel data is appropriately arranged,so as to satisfy the set up time and hold time of the address or data. The experimental results show that the two OLEDs can accurately display the reserved information,and have the advantages of high brightness,fast response speed,and wide viewing angle. The scheme has an ideal effect,and its dual-interface function can further expand its practicability and be transplanted in display terminals of relevant instruments and apparatus.
