yes , i am looking at those routines , i have found that by correctly setting the graphics area and home , then by reducing a few other not required gosubs for setting the gaphics text i have a very smooth display of the larger fonts , speed is still an issue , but at least the display is workable with the larger fonts., the small fonts are ok so far and i have rewritten the the Font Select routines so as to use the 6x8 fonts correctly and on the fly , the lib does not do this well
further improvement is need for speed , i am having trouble making the display work on 64mhz, works ok at 32mhz using the library , i have added some pauses in the send routines that set the wr,rd , data bus, but to date its not helped , can you take a look at the library
i do get some artifacts ( dots going on ) on the screen where the screen is not refreshed for an update over time , any reason why this occurs ?
cheers
Sheldon
