Meaning of the different * chip features can be found from the data sheet . It is publicly available * at www . st . com web pages . Currently the platform data is used * only for the 8 bit device . The 8 bit device has two wake up / free fall * detection units and click detection unit . There are plenty of ways to * configure the chip which makes is quite hard to explain deeper meaning of * the fields here . Behaviour of the detection blocks varies heavily depending * on the configuration . For example , interrupt detection block can use high * pass filtered data which makes it react to the changes in the acceleration . * Irq_flags can be used to enable interrupt detection on the both edges . * With proper chip configuration this produces interrupt when some trigger * starts and when it goes away . struct lis3lv02d_platform_data {/* please note: the 'click' feature is only supported for * LIS [ 32 ] 02 DL variants of the chip and will be ignored for #define LIS3_CLICK_SINGLE_X (1 << 0 )#define LIS3_CLICK_DOUBLE_X (1 << 1 )#define LIS3_CLICK_SINGLE_Y (1 << 2 )#define LIS3_CLICK_DOUBLE_Y (1 << 3 )#define LIS3_CLICK_SINGLE_Z (1 << 4 )#define LIS3_CLICK_DOUBLE_Z (1 << 5 )unsigned char click_flags;unsigned char click_thresh_x;unsigned char click_thresh_y;unsigned char click_thresh_z;unsigned char click_time_limit;unsigned char click_latency;unsigned char click_window;#define LIS3_IRQ1_DISABLE (0 << 0 )#define LIS3_IRQ1_FF_WU_1 (1 << 0 )#define LIS3_IRQ1_FF_WU_2 (2 << 0 )#define LIS3_IRQ1_FF_WU_12 (3 << 0 )#define LIS3_IRQ1_DATA_READY (4 << 0 )#define LIS3_IRQ1_CLICK (7 << 0 )#define LIS3_IRQ1_MASK (7 << 0 )#define LIS3_IRQ2_DISABLE (0 << 3 )#define LIS3_IRQ2_FF_WU_1 (1 << 3 )#define LIS3_IRQ2_FF_WU_2 (2 << 3 )#define LIS3_IRQ2_FF_WU_12 (3 << 3 )#define LIS3_IRQ2_DATA_READY (4 << 3 )#define LIS3_IRQ2_CLICK (7 << 3 )#define LIS3_IRQ2_MASK (7 << 3 )#define LIS3_IRQ_OPEN_DRAIN (1 << 6 )#define LIS3_IRQ_ACTIVE_LOW (1 << 7 )unsigned char irq_cfg;unsigned char irq_flags1; /* Additional irq edge / level flags */ unsigned char irq_flags2; /* Additional irq edge / level flags */ unsigned char duration1;unsigned char duration2;#define LIS3_WAKEUP_X_LO (1 << 0 )#define LIS3_WAKEUP_X_HI (1 << 1 )#define LIS3_WAKEUP_Y_LO (1 << 2 )#define LIS3_WAKEUP_Y_HI (1 << 3 )#define LIS3_WAKEUP_Z_LO (1 << 4 )#define LIS3_WAKEUP_Z_HI (1 << 5 )unsigned char wakeup_flags;unsigned char wakeup_thresh;unsigned char wakeup_flags2;unsigned char wakeup_thresh2;#define LIS3_HIPASS_CUTFF_8HZ 0 #define LIS3_HIPASS_CUTFF_4HZ 1 #define LIS3_HIPASS_CUTFF_2HZ 2 #define LIS3_HIPASS_CUTFF_1HZ 3 #define LIS3_HIPASS1_DISABLE (1 << 2 )#define LIS3_HIPASS2_DISABLE (1 << 3 )unsigned char hipass_ctrl;#define LIS3_NO_MAP 0 #define LIS3_DEV_X 1 #define LIS3_DEV_Y 2 #define LIS3_DEV_Z 3 #define LIS3_INV_DEV_X -1 #define LIS3_INV_DEV_Y -2 #define LIS3_INV_DEV_Z -3 #define LIS3_USE_BLOCK_READ 0 x02int default_rate;int (*setup_resources)(void );int (*release_resources)(void );/* Limits for selftest are specified in chip data sheet */ 3 ]; /* min pass limit x, y, z */ 3 ]; /* max pass limit x, y, z */ int irq2;#endif /* __LIS3LV02D_H_ */
