lis331hh-accelerometer
xod-dev/st-mems/lis331hh-accelerometer
Reads acceleration from an accelerometer based on LIS331HH IC by STMicroelectronics. It is expected the accelerometer is connected to the first hardware I²C bus.
Possible errors:
— Invalid I2C address
— Data too long to fit in transmit buffer
— Received NACK on transmit of address
— Received NACK on transmit of data
— Other error
— No bytes written. Probably due to buffer overflow
— Can't read the value

I2Cxod/i2c/i2c
ADDRbyte
I²C address. 18h by default. Some board configurations use 19h instead.
SENSnumber
Sensitivity. Can be 6 (default), 12, or 24. Defines bounds of measurements expressed in ɡ (standard gravity) units. E.g. max ±12g. The lower the sensitivity the better output precission. Inaccurate values are rounded up to a nearest correct sensitivity level.
UPDpulse
Triggers reading of the accelerometer.
OKpulse
Fires when reading is done
Zgnumber
Acceleration along Z axis. Expressed in ɡ units.
Ygnumber
Acceleration along Y axis. Expressed in ɡ units.
Xgnumber
Acceleration along X axis. Expressed in ɡ units.
