Hi friends,
From the discussions in this thread it is assumed that the more is length of display, the more registers required. When row scanning is done, data of each row is loaded to several registers depending upon number of columns i.e. for a display of 64 columns, 8 registers required to accomodate data of each row and if there are 8 rows, total 8x8 = 64 registers required for the matrix. Am I correct ? If so, in case of more big display - having 128 columns or so, how the registers will be managed since there are 96 GPRs in bank 0.
Is it practical to handle so many registers, say 15 registers per row to load/rotate data for that row or there is some other technique to scan rows? Please help this newbie.
