ccd linear image sensor

[elec_freak]

hello folks,
I am trying the ccd linear image sensors for the first time (tcd1706dg) , the sensor output is trackable on CRO but how to get the exact pixel position by reading the adc values on PIC is a problem. If somebody has done such kind of thing please guide, any kind of help will be appreciated.
thanks in anticipation

Can't you count lock pulses? It looks to me like the data is clocked out.

Thanx for the reply steve, I am able to count the pulses but when I am moving the a light over it precise pixel data I am not able to obtain . Can that be a problem with my coding??n Sorry if the question seems childish to you..

do you mean that you can't count each pixel as it comes out?

Do you have some well commented code that I can look at?

I have not done this kind of thing, but have looked into it to be able to do 360 degree scans... long story short I need more intel as I have only been able to find out that color is very difficult to do
From the looks of the datasheet though... you have four outputs to manage and you need to provide power and a clock to the chip. The fun part appears to be finding the change in voltage during the clock pulses.
What are you trying to accomplish by reading a CCD with a PIC?

Thanks steve, i'll send you the code by this evening.Thanks Gryd3, actually i am trying to detect the exact position pixel wise of a moving object.

Well, here's hoping you don't over complicate things... I often do.
In case you decide to shy away from a linear CCD, you may find this resource interesting.
