MMA8451三轴加速度计 STM32F103c8t6单片机控制程序，可以设置加速度计量程，±2g、±4g、±8g，但是程序里2g和4g模式下精度很高很准确，8g模式下采集到的数据存在问题，通过串口打印输出，显示单位是g。程序内关键部分已添加注释，希望可以帮到大家。(MMA8451 three axis accelerometer STM32F103c8t6 microcontroller control program, can set the accelerometer range, + 2G, + 4G, + 8g, but the accuracy of 2G and 4G in the program is very high and accurate, the data collected under 8g mode has problems, print output through serial port, display unit is g. The key part of the program has been annotated, hoping to help you.)
