Hello,
I am using an optical encoder to monitor the speed of a rotor. It is an Avago one, AEDA-3300 serie.
I use it recommended into the documentation from Avago :
**broken link removed**
But after one rotation of the axe I have more than expected return increment from optical encoder. I take a look on the signal, first just at PIN INT0 and INT1 ot the microchip 18F4520, with a logical encoder and an oscilloscope. I obtain :
**broken link removed**
I take a closer look on the value from optical encoder itself and with the value after processing by the DS26C32AM :
**broken link removed**
We can see that some signal modification are strange (if I can said that) : it's look like perturbation of signal.
So now my question : is that normal or not ? How can I solve that issu to have the correct time sampling and furthermore angular speed ?
Thanks you for your help,
Jean-Marie
