摘　　要：TI公司LM4F232H5QD是一款基于ARM Cortex-M4处理器核的32位微控制器。本文通过LM4F232H5QD的ADC接口与MMA7260三轴加速度传感器相连,实现了三轴加速度的数据采集。采集的数据处理后,可以用于实际项目中,测量物体的倾角以及检测老年人是否意外跌倒等。LM4F232H5QD of TI company is a 32-bit microprocessor based on ARM Cortex-M4. In this paper, the ADC interface of LM4F232H5QD is connected with MMA7260 which is a three-axis accelerometer chip, and measurement of three-axis acceleration is realized. By numerical processing, it can be applied in practice to measure the inclination and to test if elder people fall accidentally.
