vgatext.spin Variable display reset

joethumphrey

Hello all,

Using the VGA_TEXT.spin object in code I keep getting an instance when a displayed variable drops below the last character length the variables old last value is still displayed.


For instance:

text.str(string($A,12,$B,10,"Speed-fpm     " ))
    text.dec(Card)

Displays properly until speed drops below the last digit count.

100 fpm displays fine until it drops below that. That leaves me with the first 2 characters being updated leaving the last as it was.

Is there a way to fix this?

Thanks, Joe

You could print 3 more spaces followed either by X adjustment (back by 3) or 3 backspaces:

text.str(string($A,12,$B,10,"Speed-fpm     ", "   ", 8, 8, 8))

Alternatively you could introduce a print_numeric method which outputs a decimal number left/right justified including spaces for a fixed width (which would cover the max value).

You may just want to include the Simple_Numbers object (i.e., as "num")...
Then you could do: text.str(num.decf(card,4))

Awesome, simple numbers displays perfectly.

Thanks everyone.

How do I mark this as solved?
