| Abstract: | The general method and step to design Linux operating system driver was introduced and the A/D driver was developed.The Qt/E application program was successfully transplanted and A/D data curve was showed on the touch screen.The system can acquire and save the A/D data correctly and do complex arithmetic operations in high precision.The accuracy of data conversion in industrial occasions was also promoted. |
