Function Documentation

int imu_init	(	int	pinSCL,
		int	pinSDIO,
		int	pinAG,
		int	pinM
	)

Initializes the LSM9DS1 IMU module.

This function initializes the LSM9DS1 IMU module. It sets the chip to 3-wire SPI mode and starts up the accelerometer, gyroscope, and magnetometer.

Note

Defaults the Accelerometer scale to +/-8g, the Gryoscope scale to +/- 500 DPS, and the Magnetometer scale to +/-12 gauss.

Parameters

pinSCL	I/O Pin connected to the module's SCL pin.
pinSDIO	I/O Pin connected to the module's SDIO pin.
pinAG	I/O Pin connected to the module's CS_AG pin.
pinM	I/O Pin connected to the module's CS_M pin.

Returns

0x683D if both the Accel/Gyro and Mag start up successfully, or 0 of neither sensor starts.
