摘　　要：对数字温度传感器DS18B20的内外结构、工作原理进行了详细的阐述;以mini2440开发板为硬件平台,Linux2.6.29为软件平台,编写了基于Linux的DS18B20驱动程序;并将DS18B20驱动程序以模块加载的方式成功加载到Linux内核中。调试结果表明,内核能实时显示当前的温度值,且具有较高的精度。The inside and outside structure and working principle of temperature sensor DS18B20 driver are described. DS18B20 based on Linux is programmed, using mini2440 development board as hardware platform and Linux2. 6. 29 as software platform. The driver is successfully loaded into Linux kernel as a model. Debug result shows that the kernel can display the current temperature with high precision.
