DSP信息传输系统中的液晶高速信息采集模块的设计

摘要

Paper mainly describes the design of high-speed information collection module in front-end information transmission system,the scheme of realization of DSP and LCD module in detail,and the working process of GPIO and MCASP. System solves the time series problem of 16-bit parallel data, completes the text,graphics and text information,high-speed acquisition and processing;achieves a more user-friendly interactive interface . There is some reference value for research in this area and jobs.%主要介绍了在信息传输系统前端的高速信息采集模块的设计方法，给出了详细的DSP与液晶模块的实现方案。描述了GPIO和MCASP口的实际工作过程，解决了16位并行数据的高速时序匹配问题；完成了文本、图形以及文字信息的高速采集和处理；实现了比较人性化的人机交互界面。对于从事这方面研究和工作的人员具有一定的参考价值。
