8、简易计步器

在走路时通过串口查看加速度传感器的x、y、z和强度的值，会发现变化最明显的是强度值，因为强度值是综合x、y、z三个方向的值得到的矢量和，任一方向的值发生变化，强度值都会变化。所以我们选择强度值变化作为计步标准。Arduino程序如下：

<blockquote>//MicroPython动手做（20）——掌控板之三轴加速度
//简易计步器

#include <MPython.h>

// 动态变量
volatile float mind_n_BuShu;


// 主程序开始
void setup() {
        mPython.begin();
        mind_n_BuShu = 0;
        display.setCursor(0, 25);
        display.print("计步器：");
}
void loop() {
        if (((accelerometer.getStrength())>1500)) {
                mind_n_BuShu += 1;
                display.setCursor(65, 25);
                display.print("    ");
                display.setCursor(65, 25);
                display.print(mind_n_BuShu);
        }
        delay(300);
}
