摘要
根据点阵液晶显示模块SED1335在船舶电网参数检测中的应用,提出了一种控制液晶显示的实现方法。针对液晶显示控制系统中遇到的大量数据的实时高速传输问题,采用具有快速的计算能力和强大的信息处理能力的数字信号处理器。具体介绍了数字处理芯片TMS320F2812及液晶模块SED1335的功能特性和控制参数,并提出以TMS320F2812为控制核心的硬件电路,给出了C语言实现软件设计的具体方法。
Based on the application of LCM SED1335 in marine electrical networks, an implement means of dominating LCD is presented in the paper. Aiming at the high-speed transmission problem of plentiful real-time data in LCD control system,the DSP, a high powered digital signal processor having fast computation capability and strong information processing capability, is adopted. The main characteristics and control parameters of TMS320F2812 DSP and SED1335 LCD controller are introduced in details, the hardware interface design scheme based on TMS320F2812 DSP as control core is put forth and the concrete way for its software design based on the C language is given. More precision and practicality in detecting marine electrical network parameters by using the design has been proved by experimental results.
