Micro:Bit较精确的运动数据录入与分析（计步器升级版）
简介用Micro:Bit主板实现更准确地计步。（内附.hex文件、JavaScript源码、Python源码）
计步效果相对于检测振动准确。
改编自https://mc.dfrobot.com.cn/thread-30010-1-1.html
开启Micro:Bit后显示爱心即为计步中，触摸徽标查看运动数据（包含：步数、速度（Time/Steps）与数据评价）。
以下源代码已使用MakeCode成功编译。
Python源码：
def on_logo_pressed():
basic.clear_screen()
led.stop_animation()
basic.show_number(Steps)
basic.show_string("steps ")
basic.show_number(input.running_time() / 1000 / Steps)
basic.show_string("s/steo")
if input.running_time() / 1000 / Steps < 1:
basic.show_icon(IconNames.HAPPY)
else:
basic.show_icon(IconNames.SAD)
basic.pause(2000)
basic.show_icon(IconNames.HEART)
input.on_logo_event(TouchButtonEvent.PRESSED, on_logo_pressed)
x2 = 0
Steps = 0
basic.show_icon(IconNames.HEART)
Steps = 0
x1 = input.acceleration(Dimension.X)
def on_forever():
global x2, Steps, x1
x2 = input.acceleration(Dimension.X)
if abs(x1 - x2) >= 350:
Steps += 1
x1 = input.acceleration(Dimension.X)
basic.pause(500)
basic.forever(on_forever)JavaScript源码：
input.onLogoEvent(TouchButtonEvent.Pressed, function () {
basic.clearScreen()
led.stopAnimation()
basic.showNumber(Steps)
basic.showString("steps ")
basic.showNumber(input.runningTime() / 1000 / Steps)
basic.showString("s/steo")
if (input.runningTime() / 1000 / Steps < 1) {
basic.showIcon(IconNames.Happy)
} else {
basic.showIcon(IconNames.Sad)
}
basic.pause(2000)
basic.showIcon(IconNames.Heart)
})
let x2 = 0
let Steps = 0
basic.showIcon(IconNames.Heart)
Steps = 0
let x1 = input.acceleration(Dimension.X)
basic.forever(function () {
