    Default Graphical Displays with PBP3

    i wrote this graphics lib to handle led dmd's [1/4 scan dot matrix displays] in mono, red/green or rgb in varing sizes up to 128x32 pixels.
    it occured to me that with a little more effort it would make a general purpose graphic lib for nearly any display. so here it is.
    it uses mikroe fonts that you can easily generate. the variable width fonts can be up to 23 bits wide if you like.

    a driver for ssd1306, nokia and the ubiquitious 128x64 glcd are included with a small demo for each.
    note this is pic18 pbp3 only and if a mssp port is warranted then its used. there are more functions in the lib than the USERCMDS
    indicate, i never use them all. i could not be bothered making the usecmd code for everything
    i might publish the led dmd stuff at sometime when i work out dma->spi transfers with a k42


    and some fonts


    and some demos

    You've done an excellent job. Would you consider posting a small video demo to visualize the results?

    Warm wishes

    Fantastic work again Richard!

    Would you have any particular recommendations for a display to purchase for a newbie just as a play-around learning tool ?

    Regards,

    Troy

    if you don't mind waiting a few weeks the nokia 5110 from china is <$5 . the 7110 have a weird connector and are best avoided imo ,both are good size
    not too many pins needed, 3-5v ok.
    the ssd1306 are about $8 locally but they are pretty small need only two pins if you get i2c variant, 3-5v ok.
    if you catch a special at https://www.rockby.com.au/Index2012.cfm the 128x64 glcd can be real cheap < $5 but need heaps of pins to drive them 5v only.
    they all work .
