perhaps I posted it in the wrong category earlier...:

I am confused about screen resolutions, modes and so on. I think I do not understand the system.

I use my cmm2 on a vga monitor with resolution 1024,768.

so I entered "option default mode 9" because I want to "use" the pixels 1:1.

I also entered "option picomite hdmi, 1024x768.

option list:

When I now start a program without any command like resolution, mode etc...

(1 liner : Print "Hello")

the computer switches to 640x480. and it stays so in the command line.

the "current vga" changed to 640x480

if I enter now "edit" the editor opens in 1024x768 and it stays so after esc.

is "option default mode 9" incompatible with "option picomite"?

Those closed-loop steppers are really neat. I have been following a few projects that use them.

With the Picomite, any stepper can be closed-loop because we have PIO quadrature encoder interfaces (QEI)

this problem is eventually not a new problem at v7 (or my mistake):

I changed the sd card in my cmm2 (g1). everything is in order but in the status line (down at the screen) is the text recent filename + "check disk". if I take the card out (and put it back again) I can read there "... wrong disk".

what is the reason?

I am also getting the status line text recent filename + "check disk". Also removing disk and putting it back in gives "wrong disk". This on a CMM2 gen1.

Thanks for the report - it shows a trap in how these options are entered.

What the two options do

OPTION DEFAULT MODE sets the Colour Maximite 2's own display: the command prompt, the editor, the file manager, and Colour Maximite 2 programs.
OPTION PICOMITE is for running PicoMite programs. While it is set, every program that does not set a MODE starts in the PicoMite's MODE 1 - a two-colour mode - at the PicoMite resolution given in the option. That includes a one-liner like Print "Hello". When the program ends its display stays at the prompt (as on the PicoMite) until you use EDIT or FM, which use DEFAULT MODE again.

Why you got 640x480
The resolution must follow a comma:

OPTION PICOMITE HDMI, 1024x768

Without the comma, OPTION PICOMITE HDMI 1024x768 is accepted without an error but the resolution is lost, and 640x480 is used. Please check OPTION LIST: the line should read

OPTION PICOMITE PicoMiteHDMIUSB RP2350B, 1024x768

If it says 640x480, enter the option again with the comma. Then programs, the prompt and the editor all stay at 1024x768.

If you are not running PicoMite programs, OPTION PICOMITE NONE puts everything back to the Colour Maximite 2's own modes.

In the next beta

OPTION PICOMITE without a resolution uses the resolution of OPTION DEFAULT MODE (1024x768 with DEFAULT MODE 9), so the monitor keeps one resolution throughout.
A resolution without the comma gives the error "A comma is needed before the resolution".
The PicoMite's own OPTION RESOLUTION 1024x768 is accepted.
OPTION LIST shows the resolution in use as CURRENT PICOMITE resolution.
