| Abstract: | 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. |
