Data Structure Documentation

struct LIS2DW12State

LIS2DW12 driver state, owned by the driver.

Data Fields
bool	double_tap_detection_enabled	Double tap detection requested.
bool	initialized	Driver initialized.
uint32_t	int1_period_ms	Expected INT1 period in milliseconds.
RegularTimerInfo	int1_wdt_timer	Watchdog timer detecting a stalled INT1 stream.
RtcTicks	last_fifo_read_tick	Time of the last FIFO read.
AccelDriverSample	last_sample	Most recent sample, returned by peeks while streaming.
bool	last_sample_valid	last_sample holds a sample.
uint32_t	num_recoveries	Number of stream recoveries performed.
uint8_t	num_samples	Samples per FIFO batch requested by the subscribers, 0 when not streaming.
uint8_t	raw_sample_buf[DCACHE_ROUND_UP(LIS2DW12_FIFO_SIZE *LIS2DW12_SAMPLE_SIZE_BYTES)]	Raw FIFO read buffer, filled with i2c_read_register_block_dma().
bool	recovery_pending	A stream recovery is queued.
bool	rotated	Watch mounted rotated 180 degrees: X and Y are inverted.
uint32_t	sampling_interval_us	Sampling interval in microseconds, 0 when not sampling.
bool	shake_detection_enabled	Shake detection requested.
uint8_t	shake_stuck_passes	Consecutive watchdog passes with INT1 stuck high in shake-only mode.
uint8_t	wk_ths_curr	Current wake-up (shake) threshold register value.
bool	wu_active	Wake-up condition currently asserted, to report a shake once per assertion.

struct LIS2DW12Config

LIS2DW12 board configuration.

Data Fields
int8_t	axis_dir[3]	Direction of each watch axis: 1 or -1.
uint8_t	axis_map[3]	Sensor axis feeding each watch axis (0: X, 1: Y, 2: Z).
I2CSlavePort	i2c	I2C device.
ExtiConfig	int1	INT1 interrupt line.
InputConfig	int1_in	INT1 input, to read back the pad level.
LIS2DW12State *	state	Driver state.

#define LIS2DW12_FIFO_SIZE 32
