LSM9DS1 -- LSM9DS1 class constructor The constructor will set up a handful of private variables, and set the communication mode as well.
Input:
- interface = Either MODE_SPI or MODE_I2C, whichever you're using to talk to the IC.
- xgAddr = If MODE_I2C, this is the I2C address of the accel/gyro. If MODE_SPI, this is the chip select pin of the accel/gyro (CS_A/G)
- mAddr = If MODE_I2C, this is the I2C address of the mag. If MODE_SPI, this is the cs pin of the mag (CS_M)

begin() -- Initialize the gyro, accelerometer, and magnetometer.
This will set up the scale and output rate of each sensor. It'll also "turn on" every sensor and every axis of every sensor. Input:
- gScl = The scale of the gyroscope. This should be a gyro_scale value.
- aScl = The scale of the accelerometer. Should be a accel_scale value.
- mScl = The scale of the magnetometer. Should be a mag_scale value.
- gODR = Output data rate of the gyroscope. gyro_odr value.
- aODR = Output data rate of the accelerometer. accel_odr value.
- mODR = Output data rate of the magnetometer. mag_odr value. Output: The function will return an unsigned 16-bit value. The most-sig bytes of the output are the WHO_AM_I reading of the accel/gyro. The least significant two bytes are the WHO_AM_I reading of the mag. All parameters have a defaulted value, so you can call just "begin()". Default values are FSR's of: +/- 245DPS, 4g, 2Gs; ODRs of 119 Hz for gyro, 119 Hz for accelerometer, 80 Hz for magnetometer. Use the return value of this function to verify communication.

| void readAccel | ( | ) |
readAccel() -- Read the accelerometer output registers.
This function will read all six accelerometer output registers. The readings are stored in the class' ax_raw, ay_raw, and az_raw variables. Read those _after_ calling readAccel().
Definition at line 106 of file LSM9DS1.cpp.
| void readGyro | ( | ) |
readGyro() -- Read the gyroscope output registers.
This function will read all six gyroscope output registers. The readings are stored in the class' gx_raw, gy_raw, and gz_raw variables. Read those _after_ calling readGyro().
Definition at line 171 of file LSM9DS1.cpp.
| void readMag | ( | ) |
readMag() -- Read the magnetometer output registers.
This function will read all six magnetometer output registers. The readings are stored in the class' mx_raw, my_raw, and mz_raw variables. Read those _after_ calling readMag().
Definition at line 128 of file LSM9DS1.cpp.
| void readTemp | ( | ) |
readTemp() -- Read the temperature output register.
This function will read two temperature output registers. The combined readings are stored in the class' temperature variables. Read those _after_ calling readTemp().
Definition at line 150 of file LSM9DS1.cpp.
| void setAccelODR | ( | accel_odr | aRate ) |
setAccelODR() -- Set the output data rate of the accelerometer Input:
- aRate = The desired output rate of the accel.
Must be a value from the accel_odr enum (check above).
Definition at line 299 of file LSM9DS1.cpp.
| void setAccelScale | ( | accel_scale | aScl ) |
setAccelScale() -- Set the full-scale range of the accelerometer.
This function can be called to set the scale of the accelerometer to 2, 4, 8, or 16 g's. Input:
- aScl = The desired accelerometer scale. Must be one of five possible values from the accel_scale enum.
Definition at line 221 of file LSM9DS1.cpp.
| void setGyroODR | ( | gyro_odr | gRate ) |
setGyroODR() -- Set the output data rate and bandwidth of the gyroscope Input:
- gRate = The desired output rate and cutoff frequency of the gyro.
Must be a value from the gyro_odr enum (check above).
Definition at line 277 of file LSM9DS1.cpp.
| void setGyroScale | ( | gyro_scale | gScl ) |
setGyroScale() -- Set the full-scale range of the gyroscope.
This function can be called to set the scale of the gyroscope to 245, 500, or 2000 degrees per second. Input:
- gScl = The desired gyroscope scale. Must be one of three possible values from the gyro_scale enum.
Definition at line 193 of file LSM9DS1.cpp.
| void setMagODR | ( | mag_odr | mRate ) |
setMagODR() -- Set the output data rate of the magnetometer Input:
- mRate = The desired output rate of the mag.
Must be a value from the mag_odr enum (check above).

| void setMagScale | ( | mag_scale | mScl ) |
setMagScale() -- Set the full-scale range of the magnetometer.
This function can be called to set the scale of the magnetometer to 4, 8, 12, or 16 Gs. Input:
- mScl = The desired magnetometer scale. Must be one of four possible values from the mag_scale enum.
