| Abstract: | This paper introduces a 4channel temperature acquisition card based on PC104 bus. The characteristics, register structure and interfaces are described. Interface technology AT89C55W to AD7711 and its communication with PC104bus of the collecting-dates system are presented in detail, including hardware circuit, software and notice. This temperature collection card has date buffer storages and provide two usual working modes, the inquire mode and the interrupt mode. This design is worth of using for reference by other similar projects. According to the practical resuit, this design is successful and credible. |
