Hi guys,

Could you help me out ?

I am trying to look at the output on the oscilloscope,

When kept flat, shouldn't the xout and yout read 2.5 v? According to the data sheets...!!! ?

I cant read it as 2.5 V.

ADXL203... accelerometer IC.

The IC needs a 5V supply. Is this the voltage you are giving it?

It has a self test pin. (I don't know how this works.) Have you tried it? Did you get a definite result?

What output do you get? Is it 0V or 5V?

What happens if you shake the IC? It's possible that this will cause the oscilloscope trace to jump enough to generate a waveform.

hi brad,

It works fine now, I am using a lower input of 3 V instead of 5 V.

thanks for the help.
