介绍了一种TI公司最新推出的MSP430F247单片机，利用它自带的I2C模块驱动I2C总线的温度传感器TMP275。TMP275是一款具有高精度、低功耗的新型温度传感器。由于TMP275具有可编程功能，纤小的封装以及极大的温度范围，因而广泛应用于组建超小型温度测量装置。 Abstract: A new single chip microcomputer MSP430F247 which is released by TI is introduced.It can drive I2C interface digital temperature sensor TMP275 with I2C module.TMP275 is a new temperature sensor which has high accurate,low power. Because TMP275 has programmable function,small packages and wide temperature range,it is applied widely in very little temperature measurment equipment.
