The color code in EDIT for MM.INFO$() does not work. The previously reported color codes with functions in EDIT now work. Jan. |

V6.03.00RC19 PicoMiteRP2040V6.03.00RC19.zip PicoMiteRP2350V6.03.00RC19a.zip PicoMiteRP2350V6.03.00RC19b.zip Various little tweaks. Harm: I think this finally fixes the PIO bug. It was a real bug and nothing to do with the MIN version. Just a fluke whether it was seen or not. The HDMIWEB version now supports: 640x480 at 252MHz, 315MHz and 378MHz, modes 1,2 and 5 720x400 modes 1,2 and 5 800x480 Modes 1 and 2 848x480 Modes 1 and 2 800x600 Modes 1 and 2 1024x600 modes 1,2 and 3 Normal RP2350 HDMI and VGA versions reserve 320x240x2 bytes (153600) for the framebuffer. This allows all the normal resolutions that have been supported. Web functionality requires a lot of RAM so the HDMI WEB reduces the framebuffer to 320x240x1 bytes (76800) which restricts the resolutions and modes available. However there is still a good selection there including all the critical ones (320x240x16colour). Personally I find 1024x600 mode 3 is perfect for the cheap 1024x600 HDMI displays with touch. This gives 16-colours @ 512x300 resolution perfect for editing. |

Simply amazing, I'm not aware of anything better :) I bought an OV7670 some years ago and never used it. Today was the day I tried it and couldn't get a clear picture, the colours are scrambled. I tried different GP combinations but with same result. Can somebody please confirm the camera is running and provide the details?

Hi Peter, Victory !!! I tested the rc19 MIN version on 4 different platforms (GEEK, ZERO (2x), RP Pico) and on all the PIO FIFO works. Later I will test rc19 MIN on a Game*Mite, and see if this is candidate for the final version for that platform (are the speed optimizations back in ?). I noticed it still has the larger A: drive. Nice. If it runs all games, Geoff's FM, Tom's FM, and my personal tools (thermal camera / MODBUS analyzer / temperature meter) then I will report back here. Thank you for your persistence, finding what was wrong. I searched for weeks, but had no clue. Volhout Edited 2026-06-14 03:30 by Volhout PicomiteVGA PETSCII ROBOTS |

Hi dddns, Monday I can test with rc19 on a RP2040. But I have seen V60202 b5 working on an OV7670 (genuine RP pico). Originally I tried V60202 b2, and the camera was showing tearing at 252MHz. it needed 300+ MHz to work correct (tested on a SPI ILI9341). After a little tweaking from Peter, it ran correct at 200MHz. I think that was b5. I assume the 60300 series inherited the tweak. You are using a 2350. Have not tested that one. Volhout Edited 2026-06-14 03:43 by Volhout PicomiteVGA PETSCII ROBOTS |

Hi Peter, All Game*Mite games run (even your/Claude's Breakout), and PETSCII runs around 70 ms loops (14fps), pico-frog without sound artefacts, so the speed optimizations are in PicoMiteMinV60300rc19. Thank you, this will be the version I plan for the release of the 2040 Game*Mite. Only pending are my tools. But I assume these are okay since PIO works, and heap is large enough for the thermal camera. Thank you, Volhout PicomiteVGA PETSCII ROBOTS |

Hi Peter! RC19 freezes and immediately restarts if I use json$ function. (In program and command line also). Webmite 2350 version, Picocalc with Pimoroni Pico Plus 2W, PSRAM enabled. G@bor Footnote added 2026-06-14 06:00 by terekgabor Checked RC18 same issue occured. RC17 is ok. G@bor |

Hange on and you can use the actual release. Should be out within a week at the latest. G@bor: please try this PicoMite.zip Edited 2026-06-14 07:56 by matherp |

Peter! Same result, restart immediately. Before it this is printing on screen: PC=100AEBC8 LR=100A988B G@bor |

G@bor Please can you capture the json just before attempting to decode it and post it here. You can use LONGSTRING PRINT to output it Edited 2026-06-14 17:23 by matherp |

Peter I attached. It is a json output from openweather API. G@bor json.zip |

Peter! It works thanks, what caused this? G@bor |

| matherp Guru Joined: 11/12/2012 Location: United KingdomPosts: 11506 |
Running out of system heap. The json parser is very hungry. I've recoded to use MMBasic heap in an "arena" so it grabs 4K at a time and then allocates the small json requests from that. It the adds another 4K when needed. That allows the normal ram and psram to all be used if necessary |

Thanks! Sounds very good solution.  G@bor |

Can you try it with a rp2040 to see if it is a H/W or S/W issue? Do you have pullups on the I2C pins? Edited 2026-06-14 19:10 by matherp |

The camera runs perfect with this if cpuspeed is >=252000.

I'm running RP2350 at 200MHz with no capture issues but it is clearly now working for you so that's good |
