Currently to raster scan, i have three generated gates, pixel, line, and frame, and to get the gates to be up only when it is reading pixel data, i use "and" circuitry with the three generated signals. Is was wondering if there was any way i could set up this through the software, since this solution has a few draw backs. A single gate that would not have homogenous down times. (that after a certain interval it would stay down longer once and then resume its normal cycle. )
I would really appreciate any help you could offer. thanks.
