| Abstract: | A type of survey instrument with a mixed bar point and digital display function is developed based on a piece of AT89C2051 microcontroller. The software and hardware used is presented in detail and the method for multiple simulative serial port data transmission over a public line is also given. Because the design makes full use of the microcontroller's software and hardware resources, the resulted instrument has an integrated function to display in form of both digits and a 2 channel bar consisting of up to 128 points, to work for control and communication, and to be easily extended. |
