saddamhossain786 on 19 Sep 19The following application uses a 5 x 7 40-digit VFD by Noritake. Each character is written in a single cycle since all 35 anodes (Al through A35) of the 5 x 7 matrix are pinned out. The characters (1 through 40) are scanned by selective control of their respective grid, each of which is pinned out (G1 through G40). Respective anodes of all characters (A1 of Char 1 through Char 40) are connected. This format is common to most dot character or segment character displays (Figure 8-64). Multirow displays require additional control. This is usually provided through parallel access to the anodes of each additional row (Table 8-5).
