【摘要】 采用OMAP3530微处理器和Linux操作系统设计了智能全站仪,可实现距离和角度测量、参数设置及数据管理等功能.为提高系统野外续航能力和显示效果,采用TLV0832微处理器设计了双电池供电和双LCD显示硬件电路.在分析Linux 2.6.29的SPI同步串行接口驱动运行机制和驱动接口功能的基础上,提出了Linux 2.6.29的内核配置SPI驱动方法,针对TLV0832的A/D转换时序和TLV5626的D/A转换时序,设计相应的测试程序并实现了双电池显示和双LCD背光控制功能.本文设计可为全站仪GUI应用程序调用底层驱动及其他户外仪器实现双电量显示与双LCD背光控制提供参考.更多还原

【Abstract】 OMAP3530 microprocessor and Linux operating system were adopted to design an intelligent total station,which can realize distance and angle measurement,parameter setting and data management,etc. In order to improve the filed endurance and display effect of the system,double battery powered with TLV0832 microprocessor and double LCD display were designed. SPI synchronous serial interface driver operation mechanism and driver interface functions of the Linux 2.6.29 were analysed. Based on this,a kernel configuration method for SPI driving was proposed. According to A/D conversion timing of TLV0832 and D/A conversion timing of TLV5626,corresponding test procedures were designed and the display function of the double power supply and control of double LCD backlight were realized. The research can provide reference for the application of total station GUI to the driver and other outdoor instruments in order to realize the display of double electric quantity and control of double LCD backlight.更多还原
