摘　　要：本文介绍了在Windows CE.net5.0操作系统上,用基于ARM核的S3C2440A微控制器的ADC采集电压信号的系统,给出了系统的硬件结构图和A/D采样流接口驱动程序的设计方法。同时,将驱动通过Platform Builder5.0编译加入操作系统,当操作系统启动时,该驱动程序能被自动加载。测试结果表明,由ARM和WinCE组成的数据采集系统具有操作方便、运行稳定和测量结果准确等优点。Using the ADC of the 83C2440A microprocessor which is based on the ARM core on the Windows CE. net 5. 0 system, the voltage signal can directly be sampled. The hardware structure diagram of the system and the design method of the A/D sample stream interface drivers program are given. Meanwhile, the driver is added to the operating system through the Platform Builder 5.0 software compilation. The driver program will be loaded automatically when the operating system starts. The testing results show that the data acquisition system which is composed of ARM and WinCE has many advantages, such as the convenience for operating, stability for running and accuracy for the testing results, and so on.
