I am also using this display (HG25504) in a project. Does anyone know how to display larger than the standard size (5x7) characters. I can draw them in graphical format, however this uses a lot of program memory space. In the datasheet, it says that the characters in the internal character generator ROM can be spaced out up the 8x16 pixels, but I haven't been able to figure this out. I am running this display with a PIC 18F4520.
Also, I am trying to draw a graph that plots a measured voltage over time. Any ideas on how to go about doing this?
Thanks
