利用PIC32MX单片机串口实现点阵LCD驱动控制
Control of LCD Module Based on PIC32MX MCU by Using Serial Port
【摘要】 介绍了利用PIC32单片机通过串口控制内置RA8803控制器的240128LCD的方法.详细阐述了如何利用串口给液晶显示模块发送控制命令,以及利用点阵液晶显示器进行文本、图形和自定义图形等的显示,给出了硬件连接图和关键部分的源代码.测试结果表明,该方法实现了期望的显示目标.与直接并口驱动相比节省了7个I/O口.
【Abstract】 The method of control 240128 lCD with built-RA8803 controller through serial port by PIC32MX microcontroller was described.How to use the serial port to transmit commands to LCD and the ways of use LCD to display texts,picutres and custom graphics were expounded in detail.The hardware connection diagram and key parts of the source code were given.Test results showed that this method could achieve the desired objectives.Seven I/O ports have been saved compared with drive directly by parallel ports.
