9 years ago Using LSM9DS0 to log data including acc/angular speed seperately
This Arduino sketch is a demo of the simple side of the SFE_LSM9DS0 library. It'll demo the following:
- How to create a LSM9DS0 object, using a constructor (global variables section).
- How to use the begin() function of the LSM9DS0 class.
- How to read the gyroscope, accelerometer, and magnetometer using the readGryo(), readAccel(), readMag() functions and the gx, gy, gz, ax, ay, az, mx, my, and mz variables.
- How to calculate actual acceleration, rotation speed, magnetic field strength using the calcAccel(), calcGyro() and calcMag() functions.
- How to use the data from the LSM9DS0 to calculate orientation and heading.
Log Data using Array!
Edit***** use EEPROM such as the 24LC256 at chapter 21 of tronixstuff.com tutorial also use a real-time clock IC (such as the DS 1307)to track the duration
Edit 2 ***** why would you use the internal EEPROM? for situations where data that is unique to a situation needs a more permanent home. for example, sotring the unique serial number and manufacturing date of a commercial Arduino-based project - a function of the sketch could display the serial number of an LCD, or the data could be read by uploading a 'service sketch'. or you may need to count certain events and not allow the user to reset them - such as an odometer or operation cycle-counter
