NAME

adxl345 — read an ADXL345 3-axis accelerometer

SYNOPSIS

adxl345

USAGE SYNOPSIS

adxl345 [-W]

DESCRIPTION

reads the X,Y,Z acceleration values from an ADXL345 via the i2c bus.

computes the roll, pitch and yaw rotations about the X, Y and Z axis. See also: https://en.wikipedia.org/wiki/Aircraft_principal_axes

Options: -t msec polling interval in msec, default 10ms -b number use /dev/i2c-<number>, default /dev/i2c-0 -g range gravity range, default 3 - +/- 16g 0: +/- 2g 1: +/- 4g 2: +/- 8g 3: +/- 16g -N normal resolution (10bit), default 13bit

PINS

x-accel s32 out - X acceleration value
