Inserts the type system the widespread application prospect and the development potential causes it to become one of 1 century application hot spots. Inserts the type system usually faces the specific application, however, inserts type system itself not only with the general PC machine on application system different, moreover inserts between the type application which designs in view of the different concrete environment the difference very to be also big. Because inserts the type system is take the application as the center and take the computer technology as the foundation, and the software and hardware is may cut out, can satisfy the application system to target the and so on function, reliability, cost, volume, power loss strict request special purpose computer system. It may realize to other function and so on equipment controls, surveillance or management. This topic take the MC68HC908GP32 development board as a foundation, profited from ARM and so on other to insert the type development technology, the research has designed the data acquisition system .
First, we to the MC68HC908GP32 essential principle, the development technical question have conducted the analysis research, proposed in this foundation the design proposal, has carried on to the A/D module data acquisition, the SCI serial communication and on the position machine profile demonstration and so on the key partial programming analysis, using IDK and VB 6.0 and so on the procedure development debugging aids da has realized to the procedure design. Will be allowed to download the S19 document using the IDK translation through and the production which will carry out to the MC68HC908 board on, will bring the super terminal input order after Windows, will cause it to download to the MC68HC908GP32 development board, will pass through the repeatedly debugging, platoon Zha He corrects the mistake, the realization procedure accuracy. Next, arranges an on position machine application procedure with VB, uses the RS-232 asynchronous serial communication agreement, the receive lower position machine transmission data, the data display and the profile demonstration. Finally, gave the reasonable comment to the system use and the maintenance .
This design can debug after the correct movement, hopes to invest the practical application, proposed the design proposal and the design analysis method has the important reference value to the similar design .
