Take care that you specify the correct bar capabilities - of your display or driver: - - BAR_L: horizontal bars headed left - BAR_R: horizontal bars headed right - BAR_H2: driver supports horizontal dual-bars - BAR_U: vertical bars bottom-up - BAR_D: vertical bars top-down - BAR_V2: driver supports vertical dual-bars - -* edit display.c and create a reference to your LCD table: - - external LCD YourDriver[]; - -* extend the FAMILY table in display.c with your driver: - - FAMILY Driver[] = { - { "Skeleton", Skeleton }, - { "MatrixOrbital", MatrixOrbital }, - { "YourFamily", YourDriver }, - { "" } - }; - -* write the correspondig init(), clear(), put(), bar(), quit() and - flush()-functions. There's no need to use a framebuffer and display its - contents with the flush()- call (as in MatrixOrbital.c), you can directly - write to the display in the put()- and bar()-functions, and use an empty - flush()-function. But if you have a limited number of user-defined - characters, and therefore you have to do some sort of 'character reduction' - or similar stuff, you will have to use a framebuffer and the flush()-call. -- cgit v1.2.3
