Clearing LCD

[Michael]

Sorry, I didn't read closely enough.

I was under the impression the word "blank" would clear the word.

So you "space,space,space,etc" instead? $20 is the hex for the space key?

So if you have a 4 letter word to clear at line 1 cursor 1.....

LCDOUT $FE,$80, $20,$20,$20,$20 (?)

How is it written?

THANKS.

Is it this?.....

LCDOUT $FE, $80, REP " " \4

To put four blank spaces at the beginning of the 1st line:

LCDOUT $FE, $80, " "

It's a simple as that. And nothing else currently displayed on the LCD will be changed. Controlling LCD's with PBPro is awfully easy. I've had a lot more problems with quirky LCD drivers that want to work in 8 line mode but not in 4 line. But at least the programming is easy.

A quick edit. The forum software seems to want to eliminate extra spaces in my line of code, but just push the space bar on your keyboard 4 times with quote marks on either end.

You can:
a) just write on top of that location - no need to clear unless you want to
b) clear 4 digits with any of the following

LCDOUT $FE, $80, REP " " \4    ' perfect the way you have it

or

LCDOUT $FE, $80, "        "          ' 4 spaces between the quotes

or

LCDOUT $FE, $80, 32,32,32,32

or

LCDOUT $FE, $80, $20,$20,$20,$20

or
etc.

Wow...thanks Paul. I really appreciate it when I get specific information like that.

It helps me learn "completely".

Can't believe I actually had the last one right....it was an assumption. I'll stick with 4 blank spaces.....my mind likes the higher level language.

I have poor retention for hex and decimal equivalents and the like.

Some people can retain that type of info....I can't.
