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 en-durance 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 conver-sion timing of TLV0832 and D/A conversion timing of TLV5626,corresponding test procedures were designed and the dis-play function of the double power supply and control of double LCD backlight were realized. The research can provide refer-ence for the application of total station GUI to the driver and other outdoor instruments in order to realize the display of dou-ble electric quantity and control of double LCD backlight.
