HT49CVX Display SWIP Design Note
Functional Description
Because each character Panel directly controlled related Bank Data Memory (see HT49CVX Data sheet), correspdondinbly this SWIP uses Bank Data Memory control Panel. SWIP divides panel into Groups shown Fig. Each Group related byte BANK1 Data Memory. grid_assign.inc file definitions G_1~G_8 parameters, related memory units. Therefore only necessary manipulate each Data Memory unit directly control each group consequently control Panel.

HT49CVX Display SWIP Design Note
Before changing display, Group location (G1~G8) must sent panel_pos display contents sent panel_content. Before executing CLEAR, Group location (G1~G8) must sent. Note that clear function will clear contents every Group.
