gyroscope_calibration

Source code: gyroscope_calibration.py

A factory test for gyroscopes calibration.

Description

This is a calibration test for tri-axis (x, y, and z) gyroscopes.

Test Procedure

1. Put the device (base/lid) on a static plane then press space.

2. Wait for completion.

Dependency

• Device API (cros.factory.device.gyroscope).

Examples

To run calibration on base gyroscope:

{
  "pytest_name": "gyroscope_calibration",
  "args": {
    "location": "base"
  }
}

Test Arguments

Name	Type	Description
capture_count	int	(optional; default: 100) Number of records to read to compute the average.
gyro_id	int, None	(optional; default: None) Gyroscope ID. Will read a default ID via ectool if not set.
freq	int, None	(optional; default: None) Gyroscope sampling frequency in mHz. Will apply the minimal frequency from ectool info if not set.
sample_rate	int	(optional; default: 20) Sample rate in Hz to read data from the gyroscope sensor.
setup_time_secs	int	(optional; default: 2) Seconds to wait before starting the test.
autostart	bool	(optional; default: True) Auto start this test.
setup_sensor	bool	(optional; default: True) Setup gyro sensor via ectool
location	[‘base’, ‘lid’]	(optional; default: 'base') Gyro is located in “base” or “lid”.
