Agreed, and further to Peter saying this is a non-starter, with the capacity of modern SD cards, even GIGANTIC bitmap image files should not really pose a problem due to the capacity of modern SD cards. Could be an issue, if you were using some old tiny capacity cards like I am for one project(just cos I have them and don't NEED lots of space), but in that case, you would simply have to use a larger capacity card if you need to support large sized BMP images. AFAIK, none of the MMBASIC ports to any hardware, have supported anything other then BMP. I may be wrong on that, but I don't recall seeing in any of the manuals for the likes of the MM+ series or the ARMmite, that JPG or GIF formats were supported. Standard uncompressed BMP image data is easy to use I guess, as you don't need any kind of image CODEC. Smoke makes things work. When the smoke gets out, it stops! |

Peter, Can you confirm that the IO pin "open collector" function still works. OA47 reported a problem, that I can confirm with RC4. setpin 5,dout,oc pin(5)=0 'is a hard low pin(5)=1 'should be high impedance, but is hard high Edited 2022-09-27 17:49 by Volhout PicomiteVGA PETSCII ROBOTS |

The RP2040 does not have a "normal" open collector mode. The option will be removed from the manual. The programmer can simulate it by swapping between SETPIN DIN and SETPIN DOUT |

@Peter, What is blocking you to do the SETPIN DIN, SETPIN DOUT in the firmware? There is a lot of benefit by keeping the MMBasic code as much as possible transparent between platforms. In stead of removing it from the manual, which people that use micromite for decennia find confusing. Just a question... Volhout Edited 2022-09-27 19:36 by Volhout PicomiteVGA PETSCII ROBOTS |

The PicoMite code is finished subject to bug fixes. The change is non-trivial because the pin command then has to know if the DOUT is OC or not which is not tracked (not required to be on PIC or STM32) . The RP2040 does not have a true OC electrical mode like the other chips (no 5V compliant pins) so it is not unreasonable for the programmer to understand this and deal with it differently.

Hi Peter, These are excellent options, I had been using DEFAULT MODE 1, LCDPANEL CONSOLE 7 but these are a much better compromise, especially if you like colour editing. :-) Thanks for your suggestion. Regards Kevin. Edited 2022-09-27 21:38 by Bleep |

Hi Peter, XMODEM may be borked. Demonstrated with PicoMiteVGA + TeraTerm on Windows 10 (but originally seen with PicoMiteVGA + MMB4L as the XMODEM sender) 1. Start TeraTerm, connect to PicoMiteVGA 2. On the PicoMiteVGA: XMODEM RECEIVE "lazer-cycle.bas" 3. From TeraTerm: [Transfer->XMODEM->Send...] "lazer-cycle.bas" 4. On the PicoMiteVGA: RUN "lazer-cycle.bas" - don't look too closely it's not cooked yet. 5. On the PicoMiteVGA: CTRL-C 6. On the PicoMiteVGA: XMODEM RECEIVE "lazer-cycle.bas" 7. From TeraTerm: [Transfer->XMODEM->Send...] "lazer-cycle.bas" 8. The transfer hangs without getting past the first 512 bytes. I think you need to be sending a reasonably large program, and I suppose it is possible that "lazer-cycle.bas" is doing something that breaks it, but what could that be ? I think this may have been working in one of the late betas, but it is possible that something in "lazer-cycle.bas" has changed since then, it has certainly got bigger. lazer-cycle.zip Apologies that I won't be available to answer any follow-up questions this evening.

Worked perfectly when transferring/running 73000 byte file exactly as above (solar_eclipse) so you will need to try and find what you are doing that causes the problem in order for me to have a look Edited 2022-09-30 04:17 by matherp |

Thanks Peter can you provide download/link to exactly that file so I can do some more investigation on my side over the weekend. Best wishes, Tom Game*Mite, CMM2 Welcome Tape, Creaky old text adventures |

Tom, I have used the XMODEM command a lot in all devices. It is a long time since there has been any problem. I don't have a picomiteVGA with sdcard so can't run it there. I tried on my CMM2G2 and had an error HIGHSCORE_FILENAME$ not declared so didn't get very far. I notice that you change OPTION BREAK and do not restore it in your break-handler. I don't think that matters but... Jim VK7JH MMedit  MMBasic Help |

Following @thwill's procedure it does hang on the second transfer. > XMODEM RECEIVE "lazer-cycle.bas" <-------OK > RUN > XMODEM RECEIVE "lazer-cycle.bas" <-------Hangs at 512 bytes Typing CLEAR after running does not restore normal XMODEM operation. |

Hi Jim. Yes, I was a bit surprised myself. I first saw this when SENDing from MMB4L so naturally thought it was me, however since reproduced with Tera Term. Yes, it's not quite cooked yet and I haven't run it up on the CMM2 for some time; the PicoMiteVGA is for me a more interesting target. I wonder if that's it? The timeline would fit, the appearance of this problem and adding the break-handling code are both events of the last week. I will check first thing in the morning. Peter, this reminds me, should the PicoMiteVGA not automatically do the equivalent of a PLAY STOP on a break or error, the CMM2 does? Thanks, Tom Game*Mite, CMM2 Welcome Tape, Creaky old text adventures |

Thanks for confirming Phil. I suspect a NEW would do the trick. Best wishes, Tom Game*Mite, CMM2 Welcome Tape, Creaky old text adventures |

<EOT>, CHR$(4) is sent by xmodem but only at the end of all text so it shouldn't be doing anything at the time. Phil has confirmed the problem so I might change the firmware to VGA and do some investigating if time permits today. Spring time so lots to do. My guess is, there is something that gets cleaned up with a ^C that doesn't get cleaned up with a simple END. I am not sure if there is any way to simulate a ^C from within a program. 'ERROR' seems the closest but not very nice for the end user to see. Jim Edited 2022-09-30 09:05 by TassyJim VK7JH MMedit  MMBasic Help |

So what does typing Control_C do? What it says I guess but is the program still running? Bill Keep safe. Live long and prosper. |

> LOAD "lazer-cycle.bas" Loading from SD locks up the Pico. Power off / on required. Discovered previous SAVE "lazer-cycle.bas" after original XMODEM RECEIVE produced a 0 byte file. Something in there messes things up properly! |
