I went with this derivative instead: https://sites.google.com/site/beroth/i2clis3lv02dqaccelerometer – using I2C, which works fine.

Cheers!

Converting accelerations into distance through a double integration is a task for experts. The LIS accelerometers are stable enough only for a few seconds of integration before the distance error is off the charts – the error grows exponentially with time. Another basic issue is that you must always know very precisely in which direction the axes directions of the physical device are pointing, relative to the starting direction. Any unwanted miniscule rotation of the physical accelerometer will ruin the measurement. That is why you usually combine accels with gyros, because the gyros will keep track of the orientation of the accel. This is extremely complicated stuff. The only credible experiments you can do at home with a 3-axis accel is to move it back and forth in straight lines, perhaps following a ruler laid out on a table. The nice application with a pedometer does not build on a double integration to get the distance. Stay away from the double integration 🙂

I think you’re in for a bit of debugging here. Either the Arduino is not communicating properly to the accelerometer (I’ve never used the particular one you are using) — the protocol is quite particular and you want to make sure you’ve configued the accelerometer to expect to communicate in the right fashion..either I2C or SPI or something else, you’ll need to check the specifications of the device. I often run into these sorts of problems, which can be frustrating. I think the best investment I ever made was in an Oscilloscope and, even better — a digital logic analyzer like the Saleae which I reviewed here: http://www.nearfuturelaboratory.com/2008/10/24/a-new-logic-analyzer-and-an-i2c-compass/ (Saleae).

I´m not sure quick well what the problem, I´m pretty sure that the wiring its Ok. It´s keeping reads :
WHO_AM_I [FF]
WHO_AM_I [0]
no matter how its move.

Any clue or tip to check the problem, and making works….

Thanks a lot

Sorry bub. That is left as an exercise for the reader! That project is four years on by now. Should be fairly straight forward – it’s just I2C comms of the basic sort. The flow would be nearly identical and I’m pretty sure there are plenty of Propeller I2C examples out there. Please post your results though!

Could you do the same tutorial using a propeller.
