Hi Peter, I miss the option in the Picomites to insert small files in the editor with F7, like in CMM2. I found it very useful. CMM2 manual p23: Have you ever considered implementing this in PicoMite? I know that there is the option to attach a file with AUTOSAVE APPEND. But that is only an inadequate replacement. If you don't plan on doing that, I will write a small Basic tool for it. Regards Michael causality ≠ correlation ≠ coincidence |

The PicoMite editor is basically the same as the original Micromite and does not lend itself to these sort of changes. The editor in the CMM2 is completely different and uses more memory than is available on the PicoMite. In other words, no, the editor will pretty much stay as-is until I get a chip that addresses proper parallel external memory like the STM32 |

Thanks for the quick reply! Michael causality ≠ correlation ≠ coincidence |

Thanks Peter, I think I threw a DS1822 into my "PicoMite travel box" that travels with me and will give it a try. I only wish multi-million dollar companies could have response times like this when something doesn't work, would certainly make my life easier  Regards, Lyle. |

From manual: MM.INFO$(SDCARD) Returns the status of the SD Card. Valid returns are: DISABLED, NOT PRESENT, READY, and UNUSED But, USB/HDMI/RP2350, 02b11 status$=MM.Info(SDCARD) returns ->Ready, Not present (Sentence case) So 02b11 should give upper case (or user manual should be Sentence case) (Better practice for user of course would be LCASE$(MM.INFO$(SDCARD)) returns to be safe in any case  )Edited 2025-02-14 19:38 by electricat My MMBasic 'sand box' |

@Peter, Three questions if I may - embedded below within my use-cases. Currently working with Pimoroni Pico Plus 2 (ie RO2350B) with HDMI+USB firmware b11. This is on a OLIMEX PC board. Also have unpowered 4-way hub, RTC, I2S module, and usb-to-serial module to console in from laptop too (TeraTerm) Hardware wise, everything is happily working as expected. Resolution is 1280. The only thing plugged into the hub is a USB keyboard. On power up, I see the ‘MMBasic welcome message’ on TeraTerm, but not on HDMI monitor. QUESTION 1: Is the welcome message meant to be on HDMI too? About a second later (after power up) the system reports any USB devices plugged into the hub. Channel 1 correctly shows keyboard, but channel 3 is reporting an unknown device (with pid and vid values). QUESTION 2: I remember seeing a post about this before, but is this expected behaviour? If I have a program running that uses a ‘large font’ (such as a large format clock on the HDMI screen), AND if I set Option Autorun On, then on power-up, I correctly see my clock (in large font), but then about a second later, I see the USB devices listed also in large font (which totally messes up the time shown on the screen). QUESTION 3: is there a way to suppress the ‘usb device list’ so it doesn’t show at all? Thanks in advance for any clarification… |

G'day Peter, Can happily report that DS1822 parasitic mode working here both with TEMPR and ONEWIRE functions Thanks again. Regards, Lyle. |

Have a Pico Plus 2 (RP2350B) with b11 HDMI USB firmware installed. Mouse and keyboard attached to hub (and both are recognised by the Pico). Keyboard working as it should do; but mouse doesn’t seem to be doing anything. The manual implies there is nothing else to set up for the mouse however, there is no highlighted character in the Editor as implied by the manual. Is there anything I need to set to enable the mouse?? |

Definitely works. What mode and resolution - it only works in mode 1 as previously explained |

| WhiteWizzard Guru Joined: 05/04/2013 Location: United KingdomPosts: 2927 |
Thanks Peter for confirming this. However, you have previously mentioned that the editor switches to mode 1 regardless of current mode (although I have seen different font sizes in editor dependant upon mode changes at the command prompt). I do have the command prompt auto set to mode 3 at power up (OPTION DEFAULT MODE 3) but obviously it can be changed at command prompt too. Typing MODE 1 at command prompt, then EDIT to start the editor makes no difference. DEVICE USB x and y return positive -integer values but they don’t change. Don’t doubt it works, just need to know if there were a recent firmware change that needs (for example) an option set. Will try other mice too just in case…..  |

If you have the default mode 3 then the mouse won't work in the editor. Mode only switches with MM.HRES < 512. As previously stated leave defaults as-is and everything works, anything else and you are on your own Edited 2025-02-16 06:12 by matherp |

I am confused by some contradictions and now need clarification. What does OPTION DEFAULT MODE do/set? My understanding is that on power-up it will switch to this mode (with the exact pixel resolution dependent on OPTION RESOLUTION). My understanding is that this mode can be changed by using MODE x at command prompt. What does MODE do at the command prompt? My understanding is that this will switch to mode x until changed either at the command prompt or changed from the program (and upon exit of a program, the mode will remain as last set by the program) What mode does the EDITor use? You have previously mentioned it switches to mode 1 but if this is the case, why mention above that my default mode being set to 3 will mean I won’t see the mouse highlighter? I need to ensure that I understand the above fully as currently I am performing thorough testing which is required prior to several magazine articles I am writing in the very near future. It is vital I get a stable hardware setup, understand any limitations (hardware and software), and am aware of any ‘gotchas’ |

Think I need to ask slightly differently: With having set OPTION RESOLUTION 1280, is there anything I need to do/change/set to get to see the mouse-highlight in the editor? |

@Peter, Martin.H is working on a Donkey Kong game for PicoMite(2040 VGA). His code is working on 5.09.00rc5 and 6.00.01. The error message is "Not Enough Heap Memory". I would like to debug what is causing it. Is there anything you can advise we could do ? What direction to work. The game uses sprites, blit, play mod files and flac files (not at the same time). Uses framebuffer L (and N). There are not that many variables that I would worry them eating heap. The only thing I noticed is that he uses 1 sprite that is often re-programmed (same dimensions (48x36), differen data). Thank you for your advise, Volhout P.S. in his original game the error message is with a PLAY FLAC "filename" after a PLAY STOP, but when commenting parts of the game out, the error happens at a SPRITE SHOW. So it is a generic heap problem I guess. Edited 2025-02-17 22:16 by Volhout PicomiteVGA PETSCII ROBOTS |

@Peter, About 6.00.02b11 for RP2040 VGA/PS2 I have narrowed the "Not enough Heap memory" down to SPRITE SHOW n,x,y,layer,options With options=0 all works okay, with options=1 the heap error shows. The sprite is 48x36 (not square), this is horizontal mirroring. Anything you can do about it ? Martin says it worked in 6.00.01. Thank you, Volhout PicomiteVGA PETSCII ROBOTS |

Is it failing to free memory or have you just run out? Use memory command to check for a leak |

| Volhout Guru Joined: 05/03/2018 Location: NetherlandsPosts: 4854 |
RUN Program: 23K (24%) Program (828 lines) 2K ( 1%) 1 Embedded C Routine 71K (75%) Free Saved Variables: 16K (100%) Free RAM: 13K (10%) 31 Variables 82K (65%) General 29K (25%) Free [423] FRAMEBUFFER write l:Sprite show 1,x,y+yo,l,mir Error : Not enough Heap memory To be honest I was surprised it uses 82k generic memory (but it is playing FLAC at that moment, and has a framebuffer L).

You have to use memory repeatedly in the program to see if there is a memory leak when repeatedly calling sprite show. It's also best not to have compound lines to allow the memory garbage collection to work better |
