摘要
介绍了以DSP芯片TMS320F2812为CPU的有源电力滤波器中液晶模块JLX12864G-139的应用设计方法,详细说明了DSP芯片与液晶模块的硬件接口电路设计,通过分析液晶模块的读写时序,阐述了在TMS320F2812中用软件模拟时序的方法,实现了对液晶模块JLX12864G-139的控制。
The method for application design of JLX12864G-139 LCD in the active power filter, which uses digital signal processing microprecesor TMS320F2812 as its CPU, is introduced in this pater. The paper firstly introduces the design of hardware interface circuit between the DSP chip and the LCD module, and secondly elaborates the way of using software for timing simulate in TMS320F2812, by analyzing the read-write time of LCD module. Finally the controlling of JLX12864G-139 LCD module is realized.
