加速度计

介绍

The accelerometer class measures acceleration detected by the Accelerometer at different sensitivities.

类构造函数

accelerometer( 
  triport::port &port, 
  bool           bHighSensitivity = false);

类析构函数

Destroys the accelerometer object and releases associated resources.

virtual ~accelerometer();

参数

范围	类型	描述
port	triport::port &	The 3-Wire Port the Accelerometer is connected to, written as Brain.ThreeWirePort.X or ExpanderName.X, where X is the port letter (for example, Brain.ThreeWirePort.A or Expander1.A).
bHighSensitivity	bool	Sets the created Accelerometer to either a 2G or 6G Accelerometer by setting the high sensitivity mode: false (default) — Creates a 2G Accelerometer true — Creates a 6G Accelerometer

示例

// Create a 2G accelerometer instance in Port A
accelerometer Accel2GA = accelerometer(Brain.ThreeWirePort.A);

// Create a 6G accelerometer instance in Port A
accelerometer Accel6GA = accelerometer(Brain.ThreeWirePort.A, true);

成员功能

The accelerometer class includes the following member functions:

• acceleration — Returns the acceleration detected by the Accelerometer.

Before calling any accelerometer member functions, an accelerometer instance must be created, as shown below:

/* This constructor is required when using VS Code.
Accelerometer configuration is generated automatically
in VEXcode using the Device Menu. Replace the values
as needed. */

// Create a 6G accelerometer instance in Port A
accelerometer Accel6GA = accelerometer(Brain.ThreeWirePort.A, true);

acceleration

返回加速度计的重力单位换算值。

Available Functions

double acceleration();

Parameters

此函数不接受任何参数。

Return Values

对于 6G 加速度计，返回范围为 +/- 6G 的双精度浮点数；对于 2G 加速度计，返回范围为 +/-2G 的双精度浮点数。

// Drive the robot forward.
Drivetrain.drive(forward);

// Get the acceleration of accel in the range +/- 6G.
double accelerationValue = Accel6GA.acceleration();
