Function Documentation

void lis2de12_get_accel

(

struct lis2de12_accel_data *

data

)

Gets the raw acceleration values.

Parameters

data	A pointer to the structure that will hold the raw values.

void lis2de12_handle_int

(

uint8_t

pin

)

Handles the accelerometer IRQs.

The function handles the accelerometer IRQs, and must be called to clear it on the accelerometer side.

Parameters

pin	The accelerometer pin that triggered the IRQ. This can be LIS2DE12_INT1 or LIS2DE12_INT2

uint8_t lis2de12_init

(

uint8_t

i2c_port

)

Initializes the accelerometer driver.

Parameters

i2c_port

The I2C port to which the accelerometer is attached. This should be I2C_PORT_n where n is the I2C port number.

Return values

uint8_t

0 if the initialization is successful, 1 otherwise.

uint8_t lis2de12_is_enabled

(

void

)

Checks if the accelerometer is enabled.

Return values

uint8_t

1 if the accelerometer is enabled, 0 otherwise.
