Diagonal lines and wrong colours from fillRect

-

hi,

i have ili9488 3.5in tft lcd ebay. found code working, sorted out touchscreen coordinates , other stuff. i'm trying figure out why fills rectangles weird. have diagonal miscoloured lines smeared across them? can draw text absolutely perfect, doubt lcd defective. pins mismatched or something? can point me in right direction?

cheers,

you have ili9488_555 display.

install mcufriend_kbv library library manager.
enable support_9488_555 in mcufriend_kbv.cpp (edit 2 slashes in front of #define)

david.

i having trouble getting indesign recognize mathtype fonts.  have been told move mathtype fonts on 2 indesign font folder.  copied mt-extra font file mathtype folder , pasted indesign font folder.  nothing changed.  indesign still gives me blank box after copy mt-extra font mathtype -->illustrator-->indesign.   guess need instructions on how transfer of fonts done correctly.  i'v looked @ install fonts manual indesign, not clear me on how it.  need utility fontexplorer this, or there other way.  what's weird working fine until had reinstall osx , reinstall cs3, font trouble started.  need toggle "activate-reactivate' adobe cs3 , don't know how close 20 max on this, worried that.  (i suspect because of note on forum might necessary).  thoughts appreciated. i'm using windows, advice may worth nothing...   1) shouldn't have deactivate id recognize fonts. 2) design science gives fonts away in type 1 , truetype flavors....
