Set sensitivity values for the BaseAccelerometer.

Note: Sensitivity must be expressed as milli-G/LSB.; The sensitivity buffer must be at least the same size of the BaseAccelerometer axes number.

Parameters

[in]	ip	pointer to `BaseAccelerometer` interface.
[in]	sp	a buffer which contains sensitivities.

Returns: The operation status.

Return values

MSG_OK if the function succeeded.

static msg_t acc_reset_sensivity ( void * ip )

static

Reset sensitivity values for the BaseAccelerometer.

Note: Default sensitivities value are obtained from device datasheet.

Parameters

[in] ip pointer to BaseAccelerometer interface.

Returns: The operation status.

Return values

MSG_OK	if the function succeeded.
MSG_RESET	otherwise.

static

Changes the LIS302DLDriver accelerometer fullscale value.

Note: This function also rescale sensitivities and biases based on previous and next fullscale value.; A recalibration is highly suggested after calling this function.

Parameters

[in]	devp	pointer to `LIS302DLDriver` interface.
[in]	fs	new fullscale value.

Returns: The operation status.

Return values

MSG_OK	if the function succeeded.
MSG_RESET	otherwise.
