LCD going crazy!!!

[bjsunbeam]

try a pause between each lcd out
Some of the cheaper LCD's are not good with fast transfers
You can also try adjusting the LCD commandUs etc

I did try using define, same thing happens. I have been using this LCD for a couple of years now. This is happening since I upgraded to windows7 64 bit. and using microcode studio

I also changed pic, used different pins for RS RE LCDout. I just have not changed the LCD module with a new one.. maybe its the LCD ...

How about:

Mainloop:

        LCDOUT $FE,1    ' Clear display
        PAUSE 50 
        LCDOUT $FE,2," This is a test"       ' Move to 1st line, writes 15 CHAR
        LCDOUT $FE,$C0,"Next or Select"     ' Move to 2nd line, writes 14 CHAR
        PAUSE 200
            
GOTO Mainloop
End

taking a cue from Louie, I'd say, you're writing too fast for the lcd to keep pace.

You can try this

Mainloop:          
                 LCDOUT $FE,1    ' Clear display         
                 LCDOUT $FE,2," This is a test"       ' Move to 1st line, writes 15 CHAR         
                 LCDOUT $FE,$C0,"Next or Select"     ' Move to 2nd line, writes 14 CHAR 
STOP 
End

I think the revolution of the earth might of affected my chip. no but seriously I did not touch anything and it is working now...
even with pause 100 after the LCDout...
Althought i do not understand why I need these two line for my frequency:
OSCCON = %01110000 '8 Mhz
Define OSC 8


the OSCCON = %01110000 says that is is running at 8Mhz...

The program is not stable if I do not have BOTH of these lines... why ??

OSCCON = %01110000 '8 Mhz
Define OSC 8

OSSCON=%0111000 ... configures the actual PIC hardware

Define OSC 8 ... is a directive to the COMPILER to notifiy it that you have set the PIC hardware for 8 MHz
