Sorry, i'm quite new to the electronics game so i'm still learning about getting to the point with my questions.
Anyways thanks for the advice, i will search the forum for the buffer stuff.
well...and here comes a new idea
what if i could set the buffer to exactly 192 bytes? then i could simply pop the whole thing, send an ack back, wait a few ms (during which i hope the buffer fills up again) and proceed with the next frame.
This could spare me the comparing against AA55 on every 2 bytes i read, which would make the display faster i suppose..
"hope" is the word which makes me feel a bit anxious about that solution
