Salut,
thanks for the reply!
I have no flip-flop at hand and due to the Christmas break, it will take some time to get one. However, if I read the documentation right, the cross-over voltage may not fall below 2.5 Volt, so raising P2 prior to lowering P1 will move the crossing voltage to 5 V well above 2.5 V.[Edit] I guess a NE 555 chip will do as flop flop - will try[/Edit]
In my understanding of the CCD, p1 creates in the first step a trap for the charge created by the captured light. Then P2 is lowered so that the charge flows into the P2-trap and P1 is raised to avoid a flow back. Now I can read the charge into my Arduino ADC. Then, via Reset (RT), the charge is removed. P1 is now lowered to let the charge from the left P2-trap flow into the P1-trap and P2 is raised to close the trap. (Just to confirm)
Still looks like the charge transport is not working and I read out pixel 1 ...
Ciao, Mathias
