PBP 2.50 UPGRADE problems!!!!

[earltyso]

The text changes but still off position by 2 places to the left, I should now correct what I was saying earlier, ROW1 has been shifted to the LEFT 2 places NOT to the right 2 places. Either way, the problem is still there.

I also tried modifying the CONSTANTS for ROW's 2, 3, & 4,....they work fine and update with any editing, ex: Row2+4 and CON 194 change Row2 immediately.

It's just Row1

Change all of those constants from:
Row(whatever) to Ln(whatever)....
see what happens.

Also, it might be a timing problem. Shifting to the LEFT tells me it's missing an E pulse because the LCD is busy doing it's thing.
-----LCDOut 254,1-----
takes quite a bit more time to execute than the rest of the LCD commands.
Increase your LCD_COMMANDUS value or put an extra pause of a couple milliseconds after that command.

You were right! There is some kind of timing problem that has come up with the new software that wasn't there before, perhaps my oscillator is spontaneously acting weird. I am going to guess that the newest PBP has changed the whole LCDOUT 254,1 command a bit. I am currently running at 4Mhz which I know is not recommended for the LCDOUT commands, I have always run 12 Mhz before but wanted to try 4 anyway.

Thanks for your help, a small delay of 1ms seems to be enough for now until I change out the crystal.

LCDOut 254,1
pause 1
LCDOut 254,Row1, " Welcome to the "
LCDOut 254,Row2,0,1," All-In-One ",4,5
LCDOut 254,Row3,2,3," Light & Water ",6,7
LCDOut 254,Row4, " Controller! "

Thanks again!!!!!!!

Read the manual...You'll find DEFINE LCD_COMMANDUS and DATA_US. Increase those and you should be ok without the extra pause.

[earltyso]

I will be sure to do that.

Hi,

I had the same issue with PbP 2.50a some times ago ...

Thought it was my LCD a bit lazy!!!

DEFINE LCD_COMMANDUS 2000 solved that ...

May be a better PBP timing ... the datasheet told 1.62 ms !!! LOL ...

Interesting.

The default timing has been changed in 2.50

2.46 - pbppic14.lib

    ifndef LCD_COMMANDUS	; LCD command delay in us
LCD_COMMANDUS EQU 2000
    endif
    ifndef LCD_DATAUS		; LCD data delay in us (0 - 255)
LCD_DATAUS EQU 50
    endif

2.50 - pbppic14.lib

    ifndef LCD_COMMANDUS	; LCD command delay in us
LCD_COMMANDUS EQU 1500
    endif
    ifndef LCD_DATAUS		; LCD data delay in us (0 - 255)
LCD_DATAUS EQU 44
    endif

Added: And yes, it's in the manual. (sort of)
