matherp said This is correct.
To get colour you need to use the TILE command. CLS is the equivalent of BOX 0,0,mm.hres,mm.vres,0,0,rgb(red) and any colour in mono mode is white. They both use the DRAWRECTANGLE primitive. I played with interpreting the coordinates in DRAWRECTANGLE to see if the matched tile boundaries and then setting the tile colours accordingly but it has far too many unforeseen consequences that would completely bemuse the user to be a realistic option

Oh - I relied on your post saying "the default tile size will be 8x12 to match the default font 1".

Added TILE SMALL

and still doesn't work.

? mm.hres, mm.vres
640 480

Look to be OK multiples of the tile size.

Only text does the automatic colour map for the reasons I stated

i think peter is saying that tiled colours are only respected when using the PRINT command, and then only when the characters printed sit aligned on tile of the same size as the character.

john: what happens if you print 40 lines of 80 space characters, using your preferred background colour? does this give you the same effect as CLS n? and if you then place the cursor at the top left of your screen, does the background and foreground colour correctly follow any further text typed at the command prompt? including scrolling at the bottom of the screen?

please bear in mind, i don't have a colour picomite set up here to test this for myself.

cheers,
rob :-)

OK, I kinda expected CLS would work, though!
(BTW, TEXT works, too.)

Yep! Good idea!

Works (on a trivial test). Kinda slow. The manual will need some tweaks LOL

I didn't have a PicoMiteVGA either till I fought "modern" solder etc (gave up, dug out the dregs of leaded stuff I still had from 25+ years ago).

Thankfully Peter did a GREAT job of things like the Gerbers & BOM (so even I could get the right parts from JLCPCB & Farnell).

Try clearing the Mode 1 small tile screen with
TILE 1,1,foreground,background,80,40

"Modern" solder has no place here. I have a huge bobbin of the proper leaded stuff that I've been using for about forty years. :)

Mixtel90 said Try clearing the Mode 1 small tile screen with

I expect/expected x,y to count from 0 (don't know yet).

With the 80 I get:
Error : 80 is invalid (valid is 1 to 40)

and with the 40 I get:
Error : 80 is invalid (valid is 1 to 30)

I think those two are bugs :(

Using the allowed 40,30 it just does a block at the top left and leaves the rest of the screen unchanged.

hmm, interesting... after trying this, using EDIT I no longer get syntax colouring (or whatever it's called), just monocolour (white letters on black).

Mixtel90 said "Modern" solder has no place here. I have a huge bobbin of the proper leaded stuff that I've been using for about forty years. :)

I'll look to see if it can still be bought (but not a huge bobbin, it would be far too much for me LOL).

What ratio of lead/(er, copper?) do I look for please?

How odd!

With
TILE 1,1,RGB(blue),RGB(blue),40,30
I get:
Error : 40 is invalid (valid is 1 to 39)

But
TILE 0,0,RGB(blue),RGB(blue),40,30
is allowed (though not the whole screen).

Another bug?

Ah...
This is ok.
TILE 0,0,RGB(blue),RGB(white),39,29
It looks like it hasn't been updated to cope with the bigger screen because 79,39 is'n supported.

Hi John,

It is as with arrays, the starting tile is 0,0

If you have large (16x16) tiles, there are 40 horizontally and 30 vertically.

so

tile 0,0,rgb(red),rgb(blue),40,30

will fill the whole screen with background blue, forground red

But

tile 1,1,rgb(red),rgb(blue),40,30

will start at tile 1,1 (so 1 down from the top, 1 right from the left edge) and try to paint 40x30. And that does not fit. from that position (1,1) you can only paint 39 to the right, and 29 down.

Regards,

Volhout

Thanks, that's what I originally thought but then I hit the bugs.

from the VGA manual, 5.07.04, pg 84:

Quote
TILE x, y [,foreground]
[,background] [,nbr_tiles_wide]
[,nbr_tiles_high]

... 'x' and 'y' are the coordinates of the block in pixels ...

is the manual in error? it would make more sense for x and y to be tile coordinates.

a brief perusal of the manual also fails to reveal if 0,0 (for anything) is at top-left of screen, or bottom-left. traditionally - from ye olde days of BASIC - graphics had the origin at bottom left, while character positions have the origin at top left (and 1,1 as the origin). geoff: a diagram clarifying this is perhaps worth adding to the manual.

cheers,
rob :-)

addendum: ",foreground" should probably not be in square brackets, or does TILE x, y do something useful with no colours specified?

PicoMiteVGAV5.07.07b22.zip

I've managed to restore the workable memory to 100Kb and have solved the interaction between audio and the display

Also fixed the error in the TILE command

Volhout: please confirm this solves your issues

Hello Peter,

is there a possibility to set an OPTION in which when EDIT is automatically always opened in Mode 1. Even if I landed in mode 2 on the console by Ctrl+C?
Otherwise I always enter mode 1 first, edit ...

Not for me!

> option list
PicoMiteVGA MMBasic version 5.07.07b22
OPTION SYSTEM I2C GP14,GP15
OPTION COLORCODE ON
OPTION KEYBOARD GR
OPTION SDCARD GP13, GP10, GP11, GP12
OPTION RTC AUTO ENABLE

When I use EDIT via TeraTerm now, the screen on the PicoMiteVGA goes blank briefly with each cursor movement.

b22's fine for me at the default speed, though as yet I only have short bits of test code. I'm not seeing any blanking in edit.

I tried screen and putty. (Haven't used TeraTerm.)
