基于Android温度传感器驱动程序设计

Device Driver Design of Temperature Sensor Based on Android OS

在嵌入式Linux字符设备驱动开发基础上,通过深入研究Android系统架构,对Android驱动程序框架进行阐述,以此设计了DS18B20温度传感器的驱动实现方法,并在An-droid系统应用层编写测试应用,测试表明该驱动能够正常运行,成功读取传感器的有效数据.

Based on the character device driver design of Linux, the architecture studied in depth. In this article, the framework of Android device driver is elaborated of Android OS is and the DS18B20 driver on Android OS is designed. The results of test application show that the driver normally runs and the application reads the effective data successfully from temperature sensor. It verifies the validity of the drive program.
