Hi Stan,

The change to display uncaught ERRORs on the LCD was mine as I was regularly confused by programs running on the LCD apparently hanging, except they hadn't hung they had ERRORed but you could only see that by looking at the console. I don't see any downside.

The question/bug here is why a piece of code that used to work is now causing a Syntax ERROR ... probably a recent change by Peter ?

Best wishes,

Tom

if it is a translated Sprite write, Parameters are #no,x,y
The size is set while reading a sprite, not when writing

New functionality for PicoMite and WebMite

BLIT WRITE [#]b, x, y [,mode]

Will copy the memory buffer '#b' to the display. The destination coordinate
is 'x' and 'y' and the width/height of the buffer to copy is 'w' and 'h'. The
optional 'mode' parameter defaults to 0 and specifies how the stored image
data is changed as it is written out. It is the bitwise AND of the following
values:
&B001 = mirrored left to right
&B010 = mirrored top to bottom
&B100 = don't copy transparent pixels

Demo program
Box 0,0,50,50,3,RGB(green),RGB(red)
Line 0,0,49,49
Text 3,3,"hello"
Sprite read 1,0,0,50,50
CLS RGB(blue)
Sprite write 1,100,-20,6
Sprite write 1,100,220,4
Sprite write 1,-10,100,7
Sprite write 1,300,100,5
Box 0,0,70,70,6,RGB(red),0
Sprite read 2,0,0,70,70
Sprite write 2,290,90,4
Sprite write 2,-20,90,5
Do
Loop

for lcd is it blit read/write or sprite read/write please?

I believe BLIT and SPRITE are synonyms, however on the PicoMiteVGA there are additional sub-functions to BLIT/SPRITE for its software sprites ... but things change so fast around here I may be wrong

but the error message sayed that you used BLIT WRITE 3,x,y,w,h
in Line 60, and that does't work and gives you the Syntax error

BLIT WRITE in 50707 is different from
The new command is targeted for sprites, not as much for copying memory blocks to LCD.

Quote BLIT WRITE in 50707 is different from 50708.

The only difference for compatible use is that the redundant w and h parameters have been removed. If you want to do new things you can use the mode parameter but if omitted it works exactly as in 5.07.07

I flashed 5.07.07 and old LCD blit code worked ok. I'll stick with that as dunno what is for vga or lcd in Rc versions.
