Application of DSP/BIOS to the Design of Virtual Terminal of Tractor

摘要

This study explored the application of DSP real-time operating system BIOS to the software design of virtual terminal of tractors. In accordance with the functional requirements for the virtual terminal specified in ISO 11783, the hardware system for the virtual terminal controller was developed, and the method of establishing DSP/BIOS configuration files, including the configuration of various parameters used in DSP/BIOS as well as the configuration of other DSP/BIOS modules needed, is studied. This study also explained the software program frame and the program design flow for the virtual terminal. The introduction of real-time operating system enabled the virtual terminal to be operated and controlled more easily and to run more smoothly.
