| 摘 要： | 智能分析仪器要求在Windows CE系统下能够通过SPI总线实现副板与主板、主板与主板之间的数据传输。首先介绍了SPI双机通信的机理,其次分析了Windows CE下的中断处理机制的流程,最后从内核态的中断服务程序、驱动层的中断服务线程、流接口函数、驱动加载等方面实现了Windows CE下SPI双机通信的驱动程序。实验表明,两个智能分析仪器的主板之间能够可靠、稳定地传输数据。

| Abstract: | Intelligent analysis instrument requires the data could be transmitted between sub-board and main-board or among main-board based on SPI bus in Windows CE.SPI communication principle of dual machines is introduced firstly.Then,the interrupt handling mechanism in Windows CE is analyzed.At last,SPI driver of dual machines in Windows CE is implemented from the aspect of the kernel interrupt service routine,interrupt service thread,stream interface and driver load.Test results show that the data can be communic... |
