I tried the glcd demo from the repo on PICsimulatorIDE but its just
dispalying junk. I see an error in the simulator with the following message
"---------------------------
PIC Simulator IDE
---------------------------
New command or data received while graphical LCD was busy.
Graphical LCD will not behave properly and probably display some garbage
data.
Appropriate delay interval in your program should be increased.
--------------------------
I would also like to know what GLCD_DI is .
The code that i tested is given below
include 16f877a
pragma target clock 20_000_000 -- xtal frequency
pragma target OSC hs
pragma target LVP disabled
pragma target WDT disabled
;@jallib section glcd
