1. from microbit import *
   
2. #  指南针 校验
   
3. compass.calibrate()
   
4. 
   
5. #利用image的clock时钟显示的来大概指示方向
   
6. while True:
   
7.     sleep(100)
   
8.     needle = ((15 - compass.heading()) // 30) % 12
   
9.     display.show(Image.ALL_CLOCKS[6+needle])

compass的函数使用方法：

microbit.compass.calibrate()
Starts the calibration process. An instructive message will be scrolled to the user after which they will need to rotate the device in order to draw a circle on the LED display.

microbit.compass.is_calibrated()
Returns True if the compass has been successfully calibrated, and returns False otherwise.

microbit.compass.clear_calibration()
Undoes the calibration, making the compass uncalibrated again.

microbit.compass.get_x()
Gives the reading of the magnetic force on the x axis, as a positive or negative integer, depending on the direction of the force.

microbit.compass.get_y()
Gives the reading of the magnetic force on the x axis, as a positive or negative integer, depending on the direction of the force.

microbit.compass.get_z()
Gives the reading of the magnetic force on the x axis, as a positive or negative integer, depending on the direction of the force.

microbit.compass.heading()
Gives the compass heading, calculated from the above readings, as an integer in the range from 0 to 360, representing the angle in degrees, clockwise, with north as 0.

microbit.compass.get_field_strength()
Returns an integer indication of the magnitude of the magnetic field around the device.

把校正这一行可以删除，这样就不用每次启动都校正。而第一次系统会提示校正的。

有一点儿意思。
