12864-12 LCD模块与射频SoC nRF9E5的串行接口设计

本文首先介绍一种具有2位或3位串行、4位或8位并行多种接口方式，内部含有国标一级、二级简体中文字库的图形点阵液晶显示模块12864-12，以及该模块的技术特性、串行接口方式和操作指令。然后介绍射频片上系统nRF9E5的片内微控制器结构与其接口资源，给出在无线数据传输系统中12864-12与nRF9E5串行连接的硬件电路和部分程序。最后，论述了该方案的优点。

Serial Interface of LCD Module And RF SoC nRF9E5

The paper firstly introduces a multi-interface LCM 12864-12, which can either be two and three bits serial interface when used, or be four bits and eight bits parallel interface; Inside the LCM 12864-12, there are national first grade and second grade simplified Chinese library; We also introduce technical character, serial interface and control instruction of LCM 12864-12; Then presents the microcontroller and other modules of the RF SoC nRF9E5, gives the hardware and software in serial interface design between LCM 12864-12 and nRF9E5; Finally, shows the advantage of the scheme.
