I need help with displaying text using the objects - TV Text and VGA text.

I need help with displaying text using the objects - TV Text and VGA text.
I know how to display text but what I would like is to display "color text" that is colored letters.Individual letters to be in different colors but not changing the background color.I would like the back ground color to remain "Blue".

I am strictly a spin user and not a ASM user.

Thanks

Siri

You can edit your own postings. Click the little "pencil" icon, then change the title on the first posting.

In TV_Text (and looks like vga_text as well)

$0C = set color (color follows)

So your text might look like this..

text.str(string($C,5,"COLOR TEXT",13))

OBC,
The code you suggested also changes the background color.What I am looking for is to change the color of individual
letters.

Without modification I'm not sure that driver has that ability.
(Perhaps someone will jump in)

You might take a look at the AiGeneric driver which does have
the ability to change up to 16 colors. The default color for the background is black,
but I don't see why that couldn't be changed easily.

Hi Siri,

If you take a look at the TV_Text object you will find the colour palette definitions.....

                        '       fore   back
                        '       color  color
palette                 byte    $07,   $0A    '0    white / dark blue
                        byte    $07,   $BB    '1    white / red
                        byte    $9E,   $9B    '2   yellow / brown
                        byte    $04,   $07    '3     grey / white
                        byte    $3D,   $3B    '4     cyan / dark cyan
                        byte    $6B,   $6E    '5    green / gray-green
                        byte    $BB,   $CE    '6      red / pink
                        byte    $3C,   $0A    '7     cyan / blue

All you need to do is set up another palette in your top level object, like this for example, a modified TV_Text_Demo :-

CON

  _clkmode = xtal1 + pll16x
  _xinfreq = 5_000_000


OBJ

  text : "tv_text"
  

PUB start | i

  'start term
  text.start(12)
  
  text.setcolors(@mypalette)
  
  text.str(string(13,"   TV Text Demo...",13,13,$C,5," OBJ and VAR require only 2.8KB ",$C,1))
  repeat 14
    text.out(" ")
  repeat i from $0E to $FF
    text.out(i)
  text.str(string($C,6,"     Uses internal ROM font     ",$C,2))
  repeat
    text.str(string($A,16,$B,12))
    text.hex(i++, 8)


DAT
                        '       fore   back
                        '       color  color
mypalette               byte    $07,   $0A    '0      white / dark blue
                        byte    $9B,   $0A    '1      brown / dark blue
                        byte    $9E,   $0A    '2     yellow / dark blue
                        byte    $04,   $0A    '3       grey / dark blue
                        byte    $3D,   $0A    '4       cyan / dark blue
                        byte    $6B,   $0A    '5      green / dark blue
                        byte    $BB,   $0A    '6        red / dark blue
                        byte    $3B,   $0A    '7  dark cyan / dark blue

You use the command text.setcolors to change to your own Palette definitions.

text.setcolors(@mypalette)

Have fun!

Best regards,

Coley

Coley,

Thank you very much.I will make my own palette as you suggested.

I was playing witgh the "setcolors" command but had no idea· that I had to make my own palette to get the color combination I really

wanted.

Thanks once again.

Siri
