Abstract: In order to develop embedded system with sophisticated functions and high cost performance fast and efficiently,a method is proposed in the paper,by which LabVIEW could be adopted as the auxiliary debugging tools and software development environment of the host computer,so as to make use of advantages of both LabVIEW and ARM comprehensively.Then,by taking an example with the parameters self-adjusted process for 3 DOF helicopter's embedded control system,which has some defects such as finity controller system resources and inconvenience of control performance calculation,the parameters self-adjusted are realized via the cooperation of LabVIEW software working on the host computer with IAR software working on the target platform,and by making good use of the host computer's advantages such as data record,graphical appearance of data,numerical calculation,data storage,etc.Finally the effectiveness is proved by experiments.
