| 摘 要： | 为实现多通道数据准确同步采集,减小温度对数据采集的影响,利用MSP430单片机实现三通道16位A/D独立采样,同时用其内嵌温度传感器测量环境温度,根据所测温度对采样结果进行修正,通过分析了温度传感器产生误差的原因,提出了解决方法并给出了温度传感器相关的C语言程序,减小了温度变化对采样结果产生的影响。

| Abstract: | Using the Texas Instruments MSP430 to realize three independent 16-bit sigma-delta A/D conversion.Correcting the data according to the temperature from built-in temperature sensor and showing the results on LCD.Analyzing the reason caused error of temp-sensor and a method with a program to reduce the error was proposed,which could decrease the influence of temperature on data acquisition. |
