Detailed Description

Low power accelerometer driver API.

Enumeration Type Documentation

anonymous enum

The return status codes.

Enumerator
DRV_ACC_STATUS_CODE_SUCCESS	Successful.
DRV_ACC_STATUS_CODE_INVALID_PARAM	Invalid parameters.
DRV_ACC_STATUS_WRONG_DEVICE	Wrong device at I2C (TWI) address.
DRV_ACC_STATUS_UNINITALIZED	The driver is unitialized, please initialize.

Function Documentation

ret_code_t drv_acc_init

(

drv_acc_cfg_t const *const

p_cfg

)

Accelerometer driver initialization.

Parameters

[in]

p_cfg

Initialization struct.

Return values

DRV_ACC_STATUS_CODE_SUCCESS
DRV_ACC_STATUS_WRONG_DEVICE
NRF_ERROR_NULL

Returns

Other codes from the underlying drivers.

ret_code_t drv_acc_wakeup_prepare

(

bool

p_wakeup

)

Prepare for sleep and subsequent wakeup.

Parameters

[in]

p_wakeup

If false, go to deepest sleep and do not prepare to wake up the system.

Note

When the nRF prepares for sleep, the LIS3DH will wake up.

Return values

DRV_ACC_STATUS_CODE_SUCCESS
DRV_ACC_STATUS_CODE_INVALID_PARAM
DRV_ACC_STATUS_UNINITALIZED

Returns

Other codes from the underlying drivers.
