linear CCD TCD1201d readout and timing issue

Dragonsired1:
Have anybody tried reading using Mega? I tried but failed. I even changed ports in code but it didin't helped either.

I have read a similar CCD array (ILX511) using Mega but as the MCU is barely able to keep up the data rate needed the lens needs heavy shielding from light (as lesto states) else the CCD reaches saturation between reads.
