PicoMite (2).zip

Install the firmware. Type OPTION CPUSPEED 336000. This will switch to 848x480 mode (mode 10 from the CMM2). i.e. true widescreen. You may need to auto-adjust the monitor. Write a box BOX 0,0,MM.HRES,MM.VRES and then do the adjustment.

Please report success or otherwise

Tested on Vizio TV and Dell monitor. The box shows fine after auto-adjust.

For some reason if I add the circle after the box (as in your example) the screen is cleared below the cursor position before the circle is drawn leaving just the top portion of the box. If I add the box again, the screen is cleared below the cursor position before the box is drawn leaving just the top portion of the circle.

Note that I am testing on a Pico2 mini using Tera Term as that is the RP2350 that I currently have set up for VGA, thus the non-standard VGA pins.

Woah! This looks amazing!

Really really useful those new resolutions, since there are less 4:3 nowadays...

@Peter,

In the VGA and HDMI versions of the firmware, when using the EDITor, what is determining the font size (ie column and row quantities)?
Is it fixed, or is it adjustable by changing MODE (although I think you mentioned in the past that the editor uses mode 1 with tiles?), and/or does FONT change it, and/or default mode?
I guess in the non vga/hdmi versions it is determined by OPTION DISPLAY still?

Any clarity regarding this in B18 would be appreciated as I am away from home at moment and can’t test this for myself…..

Thanks for the extra resolutions (I see 720 has sneaked in there too!)
