V6.02.01b0

PicoMiteV6.01.01b0.zip

Changes from V6.02.00

All versions
You can now use string literals and string variables for GP pin nos. e.g.

const outpin$="GP2"
setpin outpin$,dout
pin(outpin$)=1

Existing usage is not affected (I hope)
SPRITE(B function now properly supports all orientations of the sprite
Fixes bug in the editor when the marked text exceeds the buffer size
F10 in the editor when in mark mode is no longer limited by the buffer size. This allows the user to mark any amount of text and save it to a file.
The editor now correctly restores non-default foreground and background colours on exit.

RP2350 versions
Reduced memory footprint of using png files - still big but not as big
SPRITE LOADPNG is modified as follows. Previously pixels under the cutoff threshold were transparent BUT black pixels were also transparent (assuming the default transparent = black). Now you can set the transparent colour to a negative value (-1 to -15) this causes black pixels to be replaced with the positive value of the negative value. So:
SPRITE LOADPNG 1,"mypng.png",-2 will replace black pixels with myrtle avoiding holes in the sprite.
load png and sprite load png now process mode 3 png files (colour map included in the file)

RP2350 only and not WebMiteRP2350
adds ray command and function

Raycaster_User_Manual.pdf

PicoMiteRP2040 and PicoMiteRP2040USB
reduces firmware image size by 16Kbyte with concommitant increase in size of A: drive.

All PicoMite and WebMite versions
N5110 driver now correctly uses INVERT in the option setting

Sometimes I'm stunned by what you get up to. Always impressed and always thankful. This is an amazing subsystem. It adds a really good set of tools. Thanks again as always. I hope that guy who's doing the CMM2 updates gets this rolled into Firmware for it as well as I would like to see what it could do with this.

I suppose it's a RP2040 but which uf2 file did you use?

> option list
PicoMite MMBasic RP2040 V6.02.01b0

So it is a plain vanilla RP2040 with no display (or anything else) attached.

OPTION DISPLAY 40, 80 is just the console window size settings.

I had "Error : Display not configured" come up on a RP2040 V6.02.00 that did have a display configured (N5110) and working.
It was triggered by using the Pulse command on a pin that had not been set as DOUT.

Footnote added 2026-02-12 12:43 by phil99
Further testing.
For pins GP0 to GP9 there is only "Error : Pin 12/GP9 is not an output"
For pins above GP9 this happens:-

> pulse gp25, 9
Error : Pin 43/GP25 is not an output
Error : Display not configured
Error : Display not configured
Error : Display not configured
Error : Display not configured
...
until lockup

Hopefully this fixes the various issues. I've forced a flash reset when it is loaded for the PicoMite and WebMite versions which should clear old config which was causing problems

As a matter of interest that version loads onto this PGA2350. I can't XMODEM the opt file from my PC though. Possibly that's a version issue? Heartbeat works ok.

V6.02.01b1

PicoMiteV6.02.01b1.zip

Adds new commands

SAVE DATA fname$, address, nbytes

LOAD DATA fname$, address

Load and save memory to file as binary data. NB: there is no protection on the address so use with care. Tested saving and loading from the screen in the VGARP2350 version

save data "test.dat",mm.info(writebuff),38400
load data "test.dat",mm.info(writebuff)

Nice. A program suicide command. ;)
Does it use the HCF command in assembly language?

Now there are several (*), though not quite HCF.

(*) POKE & CSUB at least

V6.02.01b2

PicoMiteV6.02.01b2.zip

Fixes bug in GPS parsing
Editor now correctly colour codes string literals and comments split across continuation lines

NB:
Other than the RAY command for the RP2350 6.02.01 is a minor maintenance release to pick up the few bits and pieces identified in 6.02.00. AFAIK with the above there are no known bugs. If you know of anything please post here - BUGS NOT CHANGES

Volhout

Did you ever try this before and did it work?

Perhaps there's a typo in the manual and it should be 'DRIVE FORMAT "A:/"' ?
