## Function Documentation

## ◆ inv_icm426xx_get_st_bias()

int inv_icm426xx_get_st_bias | ( | struct inv_icm426xx * | s,
|  | int | st_bias[6]
| ) |  |

Retrieve bias collected by self-test.

Parameters

  [in] | s | Pointer to device.
  [out] | st_bias | Bias scaled by 2^16, accel is gee and gyro is dps. The buffer will be filled as below. Gyro LN mode X,Y,Z Accel LN mode X,Y,Z

Returns
  0 on success, negative value on error.

## ◆ inv_icm426xx_run_selftest()

int inv_icm426xx_run_selftest | ( | struct inv_icm426xx * | s,
|  | int * | result
| ) |  |

Perform hardware self-test for Accel and Gyro.

Parameters

  [in] | s | Pointer to device.
  [in] | result | Containing ACCEL_SUCCESS<<1 | GYRO_SUCCESS so 3

Returns
  0 on success, negative value on error.

## ◆ inv_icm426xx_set_st_bias()

int inv_icm426xx_set_st_bias | ( | struct inv_icm426xx * | s,
|  | const int | st_bias[6]
| ) |  |

Apply bias.

Parameters

  [in] | s | Pointer to device.
  [in] | st_bias | Bias scaled by 2^16, accel is gee and gyro is dps. The buffer must be filled as below. Gyro LN mode X,Y,Z Accel LN mode X,Y,Z

Returns
  0 on success, negative value on error.
