Member Data Documentation

disp_data

disp_data out std_logic_vector ( 14 downto 0 )

Port

Typically the data fed to display (single or multiple) is provided for single display at a time. If multiple displays are required together with data goes display select (according typical dynamic display indication).

disp_sel

disp_sel out std_logic

Port

If more displays needs to be fed change disp_sel to vector with length equal to number of displays. Use principles of the standard dynamic indication: provide data then enable the displays sequentially. If brightness control is desired just AND the selector and the PWM controller output.
