Or tell me how to have it with linux?
Thank you in advance

Re: the axis values under Windows and under Linux are different
I forgot to clarify that I have a 3-axis JW24F8

the axis values under Windows and under Linux are different
I tried the program under windows, axes values were :
X_min = Y_min = Z_min = -250
X_max = Y_max = Z_max = 250
While Linux file joytest.c we have:
X_min = -16000
X_max = 16000
Y_min = -14000
Y_max = 18000
Z_min = -10000
Z_max = 22000
How do I get the values of windows under linux?
X_min = Y_min = Z_min = -250
X_max = Y_max = Z_max = 250
While Linux file joytest.c we have:
X_min = -16000
X_max = 16000
Y_min = -14000
Y_max = 18000
Z_min = -10000
Z_max = 22000
How do I get the values of windows under linux?

Re: Calibrate JW24F8 on Linux
It's the resulting vector between axis X and axis Y. With Pythagorus the problem is the sign.
I have an other question, how can I do an average of the Axis?
I'd like to make an average of 10 samples, for a smoother signal.

Sampling Period for JW24F8
Hie,
I would like to know the value of the Sampling Period for JW24F8.
I need this because I have to calculate the speed.
I wait for your response.

Re: Calibrate JW24F8 on Linux
I have to calculate the angle between the axis X and axis Y.
Using the formula = arctan (y / x) I always find zero in rotation.
How can I do?
Please

I found this file:

and I wanted to use the formula to find Ax.

Re: Calibrate JW24F8 on Linux
and the voltage output from the X-axis? How can I have this value? Help me please...

Hie,
Do yo know the value of the offset voltage for the JW24F8??

Re: Calibrate JW24F8 on Linux
It's good I managed to calibrate by moving the z axis, now I have to represent these 3 axis on a graph, do you have an idea?

Re: Calibrate JW24F8 on Linux
There is somebody who have an idea, or better a syntax??
Resume: when I press Space key on the keyboard, all details of 3 axes take a new position 0
For example:
We mount the accelerometer on a table and pressing the space bar, the coordinates must be zero:
x = 0, y = 0, z = 0.
