driver: lis2dw12: Add driver support
Added ACC LIS2DW12 driver support.
Features included in this driver are:
- Basic Sensor Read acceleration data
- ODR and FS runtime configuration
- FIFO support with watermark interrupt events
- Shared commons function with ST MEMs devices
- Switch Low Power to High perf. mode in case
of ODR > 200 Hz
- Configure D-TAP event detection in Hardware
BUG=b:73546254
BRANCH=master
TEST=Tested on discovery_stmems target BOARD with
LIS2DW12 connected to EC i2c master bus and motion
sense task running.
To build firmware for discovery_stmems target with
LIS2DW12 sensor connected, simply uncomment
CONFIG_ACCEL_LIS2DW12 define in board.h target file
and make with target BOARD=discovery_stmems.
Commands used to test LIS2DW12 device are:
- accelinit 0 (to configure accel. device)
All basic features tested, including changing
in ODR:
- accelrate 0 10000 (set ODR to 10 Hz)
- accelrate 0 12500 (set ODR to 12.5 Hz)
- accelrate 0 25000 (set ODR to 25 Hz)
- accelrate 0 50000 (set ODR to 50 Hz)
- accelrate 0 100000 (set ODR to 100 Hz)
- accelrate 0 200000 (set ODR to 200 Hz)
- accelrate 0 400000 (set ODR to 400 Hz)
- accelrate 0 800000 (set ODR to 800 Hz)
- accelrate 0 1600000 (set ODR to 1.6 kHz)
Full Scale Range:
- accelrange 0 2 (set Full Scale Range to 2g)
- accelrange 0 4 (set Full Scale Range to 4g)
- accelrange 0 8 (set Full Scale Range to 8g)
- accelrange 0 16 (set Full Scale Range to 16g)
FIFO features and interrupt management:
- accelinfo on 1000 (motion info task with
refresh rate 1 s)
and polling data read:
- accelread 0 (to read data from accelerometer)
