摘要
论文设计了一种基于串行总线RS-485的深度指示器,并给出了接口电路图。深度指示器的核心控制部分选用AT89C52单片机。该单片机通过RS-485总线与上位机连接,不断的接受相关数据,通过I2C总线驱动数码与LED显示部分,实时的显示被检测物体的速度及位置信息。
The paper had a design on a depth indicator base on RS -485 serial bus and provided an interface circuit drawing. The AT89C52 micro controller was adopted for the key control part of the depth indicator. The micro controller was connected with the host computer via the RS -485 bus to receive the related data continuously. The data and LED display part driving by the I2C bus could on - time display the speed and location information of the object measured.
