so the datasheet for this part isn't clear on some stuff for me and i'm still wet behind the ears with this part so bear with me.
the DE generator is a little confusing as to what it really does.
i understand it handles the data enable state for the system so if there is no DE signal going into this thing you can still write to the panel. if i am wrong on that please correct me.
one thing that it looks like it might also do is handle positioning the image on a bigger screen so your oddball image (say 1024x600) can sit in the middle of a 1280x720 screen. is that right? is that the point of the DE_TOP and DE_DLY? it would make sense based on my interpretation of the graphic on page 16 of the datasheet. the main screen is in the middle surrounded by a black border that is DE_DLY and DE_TOP many pixels big...right? if i am wrong then what is the true purpose of DLY and TOP?
also my question on the V_RES and H_RES values. one thought i had was that they represent the pixel height and width of the image you are trying to output, right? but they are not the pixel dimensions of the image i am actually putting out there so it makes me think these numbers represent the biggest i can get using this configuration? are one these ideas right? if they represent the biggest i can output then are the values adjustable if i change clock frequencies?
