anupam19 / adxl345driver Goto Github PK

Hi there!

Thanks for this awesome driver! I'm using it for my orientation sensing 
library.. see 
http://www.varesano.net/blog/fabio/initial-implementation-9-domdof-marg-imu-orie
ntation-filter-adxl345-itg3200-and-hmc5843-a which will be part of my FreeIMU 
project.. see

mu and https://launchpad.net/freeimu/

I'd like to ask a few questions about accel_cal.py. What does this script 
actually does? I see some kind of optimization but I'm not sure how to use it.. 
I guess it is something similar to what is explained on this document 
http://www.st.com/stonline/products/literature/an/17353.pdf

So, I'm wondering.. how do I use this script? What's the expected file format 
of the .dat file? How does the accelerometer has to be moved to collect the 
.dat file data? What are it's outputs? How do I use them in the driver code?

My guesses from fastly looking at the code: 
.dat file format is "Xval Yval Zval\r\n" repeated for many lines
Outputs is something useful for populating the gains array in ADXL345::ADXL345()

Thanks for any kind of help!

Take care,

Fabio Varesano

I'd say that it would be easier for a newbie user if you would stick to Arduino 
default Serial baud speed of 9600 instead of using 57600.

They should work just as fine and with less hassles to the newbie.

Here you find my most updated version which supports Arduino 1.0 APIs.

File ADXLRun345.ped in the example/ADXL345Run directory needs to be renamed to 
ADXL345Run.pde in order to work as library example (and as regular Arduino 
sketches)

I would also suggest keeping the naming similar between the two examples. 

So, as you already have ADXL345_test, why not use ADXL345_run?

I changed double xyz[3], gains[3], gains_orig[3]; to
float xyz[3], gains[3], gains_orig[3]; it works fine with arduino 1.0

Library does not work with the new Arduino IDE
