加速度计#

加速度计测量机器人沿一个或多个轴的加速度。该传感器输出模拟电压，该电压会根据加速度（以G力为单位）而变化。

加速度计上的跳线决定了其灵敏度范围：

  • 2G – 测量从 -2G 到 +2G 的加速度

  • 6G – 测量从 -6G 到 +6G 的加速度

VEX V5 模拟加速度计。

This page uses accel_a as the example Accelerometer name. Replace it with your own configured name as needed.

以下是可用方法列表：

  • acceleration – Returns the acceleration detected by the Accelerometer in Gs.

  • changed – Registers a function to be called whenever the Accelerometer’s value changes.

构造函数 – 手动初始化和配置加速度计。

加速度#

acceleration returns the acceleration value from which axis is connected on the Accelerometer as a float.

Usage:
accel_a.acceleration()

参数

描述

此方法没有参数。

已更改#

changed registers a function to be called whenever the Accelerometer’s value changes.

Usage:
accel_a.changed(callback, arg)

参数

描述

callback

先前定义的 函数，当加速度计的值发生变化时执行。

arg

可选。包含要传递给回调函数的参数的元组。有关更多信息，请参阅使用带参数的函数。

 
def my_function():
  brain.screen.print("Value changed")

# Call my_function whenever accel_a's value changes
accel_a.changed(my_function)

构造函数#

Constructors are used to manually create Accelerometer objects, which are necessary for configuring an Accelerometer outside of VEXcode.

Accelerometer#

Accelerometer creates an Accelerometer.

Usage:
Accelerometer(port, sensitivity)

范围

描述

port

The 3-Wire Port that the Accelerometer is connected to:

  • On the V5 Brain – brain.three_wire_port.x where x is the number of the port.
  • On a 3-Wire Expander – expander.a where expander is the name of the expander instance.

sensitivity

Optional. Whether to enable high sensitivity mode on the Accelerometer:

  • True – Enable high sensitivity (+/- 2g)
  • False (default) – Enable low sensitivity (+/- 6g)

 
# Create a high sensitivity Accelerometer in Port A
accel_a = Accelerometer(brain.three_wire_port.a, True)
