摘要
针对双谱段电晕探测系统的开发需求,以Atmel的RM926EJ-S微处理器AT91SAM9G45与嵌入式操作系统Linux3.0.4为系统工作平台,在分析Linux下I2C设备驱动模型和输入子系统模型的基础上,详细介绍了矩阵键盘输入设备的驱动配置过程、内核代码移植及其应用程序接口。测试结果表明:该驱动运行稳定可靠,到达预期目的。
Considering the development of a bispectrum corona detecting system,a hardware platform was built with AT91SAM9G45 microprocessor and Linux3.0.4 embedded operation system. Based on analyzing the mod- el for I2C device driver and input subsystem under Linux OS, the matrix keyboard driver configuration, the Linux kernel code transplantation and the interface of application program were introduced. Tests results show that this driver can meet requirements as expected and works stably.
