Suggestion for a possible extension to:

OPTION COLOUR VGA OFF

To allow the same hardware to be used for both colour and monochrome in any colour would it be possible switch in extra video output pins in mono mode?
eg

OPTION COLOUR VGA OFF, GP18, GP19, GP20 ,GP21

If any/all of the above pins could be selected then the full RGB(1,2,1) range would be available. If no pins are entered the current default would apply. This way there is no need for an emitter follower to get white.

Does anyone think this is worth Peters time and effort?

Not possible. Each pin needs a bit in the framebuffer to drive the PIO routine

Ok, thanks for looking at it Peter. Plug-in modules will do the job.

matherp said The syntax (manual page 75) is:

BITBANG WS2812 type, pin, nbr, value%[()]

for the Maker Pi Pico use:

BITBANG WS2812 O, GP28, 1, value% or RGB(whatever)

The syntax in the manual page 75 is correct but the description needs amending to mention the case of a single LED

This worked, but the documentation for Maker Pi Pico says it is WS2812 B, and that also works, see page 2 in https://cdn-shop.adafruit.com/product-files/5160/5160_Maker+Pi+Pico+Datasheet.pdf.

I ported an old program I originally wrote for TinyBASIC (32 bit) to PicoMiteVGA MMBasic Version 5.07.03b4: Aritm, a mental calculation trainer:
https://github.com/mobluse/aritmjs/blob/master/aritm-mm.bas. That uses the RGB LED and audio on Maker Pi Pico Rev1.2 by Cytron.

Maker Pi Pico Rev1.2, DuinoMite-Mini, Raspberry Pi 0-4, iCE40HX8K, Arduino Uno, VM111, STK500, ZX81

Hi Peter,

Use of argument/wildcard with FILES command appears to have stopped working, I'm 99.99% sure it was working previously:

> ? MM.Info(Device)
PicoMite
> ? MM.Info(Version)
5.070304
> files
A:/
<DIR> cmm2-basic-challenge
<DIR> cmm2-forth

Then what are lines 880-883 of FileIO.c for ?

if(*cmdline)
p = getCstring(cmdline);
else
p = "*";

Like I said I'm pretty certain this was working earlier.

Also note the source on GitHub contains two FileIO.c files with different name capitalisations.

Best wishes,

Tom
