readAngularVelocity

Read angular velocity measured by the gyroscope along x, y, and z axes

Syntax

angularVelocity = readAngularVelocity(mysh)

[angularVelocity,Ts] = readAngularVelocity(mysh)

angularVelocityRaw = readAngularVelocity(mysh,'raw')

[angularVelocityRaw,Ts]= readAngularVelocity(mysh,'raw')

Description

angularVelocity = readAngularVelocity(mysh) returns the angular velocity measured by the Gyroscope along the x, y, and the z axes. The unit of measurement for the Gyroscope raw data is radians per second (rad/s).

[angularVelocity,Ts] = readAngularVelocity(mysh) returns the angular velocity measured by the Gyroscope along the x, y, and the z axes with timestamp. The unit of measurement for the Gyroscope raw data is radians per second (rad/s).

angularVelocityRaw = readAngularVelocity(mysh,'raw') returns the angular velocity measured by the Gyroscope along the x, y, and the z axes. The ‘raw’ argument is to specify that the output should be a uncalibrated raw data.

[angularVelocityRaw,Ts]= readAngularVelocity(mysh,'raw') returns the angular velocity measured by the Gyroscope along the x, y, and the z axes with timestamp. The ‘raw’ argument is to specify that the output should be a uncalibrated raw data.

The full scale range for the Gyroscope is 4.27606 rad/s.

Examples

Read Angular Velocity

You can read angular velocity measured by the Gyroscope.

angularVelocity = readAngularVelocity(mysh) 

angularVelocity =  

      -0.0617   -0.0596   -0.0140  

Read the angular velocity measured by the Gyroscope.

Read Angular Velocity with Timestamp

You can read the angular velocity measured by the Gyroscope along with the time stamp at which the data was read.

[angularVelocity,ts] = readAngularVelocity(mysh) 
 

angularVelocity = 

   -0.0665   -0.0612   -0.0142 

ts =

Read the raw uncalibrated angular velocity measured by the Gyroscope.

Read Raw Uncalibrated Angular Velocity

You can read raw uncalibrated angular velocity measured by the Gyroscope.

angularVelocityRaw = readAngularVelocity(mysh,'raw') 
 

angularVelocityRaw = 
   -9.4754   -9.3532   -1.8322 

Read Raw Uncalibrated Angular Velocity with Timestamp

You can read the raw uncalibrated angular velocity measured by the Gyroscope along with the time stamp at which the data was read.

[angularVelocityRaw,ts] = readAngularVelocity(mysh,'raw') 
  

angularVelocityRaw = 

   -9.4754   -9.3532   -1.8322 
 
ts =

Read the raw uncalibrated angular velocity measured by the Gyroscope with the timestamp.

Input Arguments

mysh — Connection to SenseHAT

SenseHAT object

Connection to a SenseHAT board, specified as a sensehat object.

raw — Argument to specify the output type

Argument to specify that the output should be a uncalibrated raw data.

Output Arguments

angularVelocity — Angular velocity measured along the x,y, and the z axes

scalar

The angular velocity measured by the accelerometer along the x,y, and z axes. This is a 1x3 double data. The unit of measurement for the angular velocity is radians per second (rad/s).

Ts — Timestamp

scalar

Time at which the data is read.
