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). \mbox{\Hypertarget{class_display_driver_wrapper_ac39d5faa22b7c7b88914e8915f901d69}\label{class_display_driver_wrapper_ac39d5faa22b7c7b88914e8915f901d69}}

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 A\+ND the selector and the P\+WM controller output.
