摘要
阐述了设计Linux操作系统驱动的一般方法和步骤,并开发了嵌入式Linux操作系统的A/D驱动程序。成功移植了Qt/E应用程序并将A/D数据曲线显示在LCD触摸屏上。实验结果表明,该系统正确地实现了A/D数据采集与存储功能,并可以在较高的精度上进行较复杂算术运算。提高了工业场合的数据转换精度。
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 promoled.
