【Abstract】 The characteristic of the ultra- low power microcontroller MSP430F1121 and the digital temperature sensor DS18B20 is in- troduced. A mini- temperature detecting system is designed combining the 4 bits segmented LCD module LCM046 and the DC- DC converter MAX1674. Some primary C430 functions are presented in the IAR Workbench IDE. Using the ultra- low power of the MSP430 microcontroller and the 1- WARE interface mode of the DS18B20, the ultra- low power、simple structure、stable performance and practicality of the whole system is realized.更多还原
