It is just the tokenised version in flash which will exhibit this. You should always expect to reload from disk after flashing a new version Should do Forgot to mention on b15 that the math window command now accepts two optional parameters MATH WINDOW inarray(), scalepoint1, scalepoint2, outarray() [, min, max] If variables are specified as these parameters they will be loaded with the minimum and maximum values of inarray() Edited 2023-09-05 17:10 by matherp |

MMEdit will have the facility to change C type comments to the usual ' (but not the other way) It follows the rules from Peter so doesn't catch end-of-line comments It can be useful when converting C to Basic. It would be boring if things like this didn't crop up occasionally Jim VK7JH MMedit MMBasic Help |

For multi-programming language users, please supplement ' and REM with //. That would be really helpful. Gregor |

No: There is a Basic standard single character comment initiator. There wasn't the capability for multi-line comments. I decided to use the C delimiters as an easy shorthand but could have used REM START/REM END to be more "Basic" |

Thanks for adding /* and */, which are useful commands in the editor. Also thanks for the many nice additions after V.5.07.07 for PicoMite, WebMite (also for MMB4W). Keep it up. Unfortunately I have not been able to test PicoMiteVGA yet and I am still looking to see if there are any Dutch users who have an empty PCB for VGA that they can take over? There are some bugs in V.5.07.08b15. (checked on PicoMite, PicoMiteVGA, WebMite). I completely erased the flash memory and then flashed the update V.5.07.08b15. After exiting Edit with F1 or F2, an automatic Control Reset terminal is no longer displayed? It does work manually from Tera Term (can be seen because I adjusted the font colors in Tera Term). With List Commands there are multiple Cat commands. Jan |

If you want a PicoMite VGA board I've done several variations for different purposes (see my sig). Very easy and cheap to get a batch of five from JLCPCB. The simplest setup is a Pico, a VGA socket and four resistors. :) Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

Mick, I have seen all the PCB designs and also looked at JLCPCB, but my problem is that I do not have a PayPal account yet and I no longer have a credit card and I make all my payments with iDEAL or a bank transfer, which is for AliExpress or Banggood or a Dutch company. website has no problems.

If you don't get a local response send me a PM and I'll see what I can do. I have a few PCBs and postage to the Netherlands isn't outrageous. Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

@Peter, Is it possible to publish the start address of N,L and F framebuffers ? Let me explain: I am looking into a port of The 8bit guy's PETSCII ROBOTS to MMBasic on the picomiteVGA. The first investigations shows that the 8x8 custom font is a no-go. It is too slow to do that in MMBasic. Alternative is to create tiles 24x24 compliant with the original game. These "sprites" could blitt into the L and N frambuffers. The number of 64 (sprites) could be sufficient for a simplified version of the game (skip some animations). But 64 sprites uses roughly 64kbyte RAM. A layer framebuffer = 38.5k A world map = 5 kbyte if stored as array of strings 64 sprites = 64k This leaves not enough DATA RAM memory for a elementary game. Alternatively I could load the 64 sprites into the F framebuffer (just use it for storage, not as an actual framebuffer). The framebuffer could hold roughly 130 sprites (24x24). But I have not found a way to copy area's from one framebuffer to another framebuffer. So I am investigating a memory copy from F to N (or F to L). I am pretty sure F to N will work fine, but F to L may still require SPRITE WRITE to handle the transparency. Not sure. If I have the start memory address, I may be able to use memory copy. It may require some "tuning" but with the skip function in memory copy it may be possible (copy 3 byte, skip 37 bytes (320/8 - 3), copy 3 byte, etc...) Thank you in advance for your help.

I believe you can get these values by activating the framebuffer of interest and calling MM.INFO(WRITEBUFF). Ambitious  .What exactly do you mean by "too slow" ? Fonts and PRINT/TEXT are pretty fast ways of blitting to the MMBasic display also look at GUI BITMAP which @Martin H used for PicoVaders and is available on both PicoMite and PicoMiteVGA. If your reply is extensive then perhaps start a new thread. Best wishes, Tom Game*Mite, CMM2 Welcome Tape, Creaky old text adventures |

Hi Peter Unfortunately the WEB SCAN a%() is outputting 'Performing wifi scan' to the console, notwithstanding OPTION WEB MESSAGES OFF. Where does one post manual typos? Really enjoying /*_*/. Thanks very much. Cheers Carl Retirement is tough on Hobbies without a day job |

Hidden gem ? This is not in the picomite VGA user manual (FRAMEBUFFER BLIT). Volhout Edited 2023-09-11 16:47 by Volhout PicomiteVGA PETSCII ROBOTS |

@Peter, PicomiteVGA 50708b15 I try to use SPRITE SCROLL to scroll the background in a game. The background is on layer N, forground is layer L. As soon as I also create a framebuffer, the scrolling does not work anymore. This (demo) code is simplified, in that it does not build the background out of sprites, but loads a BMP. But the behavior is the same when using sprites. Regardless if I place these sprites with SPRITE WRITE, or with SPRITE SHOW n,x,y,0 (layer 0). MODE 2 'FRAMEBUFFER create 'scratchpad FRAMEBUFFER layer 'top 'try to load some BMP into the framebuffer FRAMEBUFFER write n Load image "title.bmp" Do :Loop While Inkey$="" 'write screen border FRAMEBUFFER write l CLS RGB(white) Box 0,0,240,8*24,24,RGB(white),RGB(black) FRAMEBUFFER write n Do :Loop While Inkey$="" 'scroll screen For i=1 To 10 Sprite scroll 1,-1 Print @(0,0)i Pause 100 Next i Do :Loop While Inkey$="" End The BMP used title.zip Run the program, and see the background scroll. Then un-comment line 3 (you also create a frame buffer) And the scrolling does not happen anymore. What did I do wrong ? Volhout PicomiteVGA PETSCII ROBOTS |

Please try the attached. The scroll functions were locked to the wrong buffer when a framebuffer was created (but not a layerbuffer) PicoMiteVGA.zip |

Hi Peter, The SPRITE SCROLL works. Thank you for the quick fix. Is there any chance of getting the FRAMEBUFFER BLIT in VGA, or should I put my focus on my MEMORY COPY idea (copying from memory to memory) ? I noticed that Tom's suggestion MM.INFO(WRITEBUFF) works, so I have the write buffer start adresses for all buffers.. Thanks, Harm Edited 2023-09-12 00:55 by Volhout PicomiteVGA PETSCII ROBOTS |

Isn't MEMORY COPY going to be slow as you have to call it once for each line ? TBH rather than the current situation of two additional full-screen frame buffers I would have preferred the ability to use INTEGER arrays as arbitrary sized (limited to multiples of 4) frame buffers (the first element would store width and height, sometimes you don't need/want the whole screen) and then blit both between them and to and from N. However I'm not in the driving seat or in any position to contribute at the moment  . Note I'm not sure how the extra capabilities of the L buffer - which I still don't fully comprehend - would translate to such a model.Best wishes, Tom Edited 2023-09-12 01:22 by thwill Game*Mite, CMM2 Welcome Tape, Creaky old text adventures |
