Abstract :
In this paper, a multiplex temperature collecting system is achieved based on 1-wire digital thermometer DS18B20 and USB2.0 interface chip ISP1581. Two MCUs are used in the hardware circuits. One is used to collect the temperature, and the other is used to control the USB interface chip. We adopt Keil C language to develop firmware program, while WINDDK to develop the device driver.
