The problem with "files" command still exists for me in b12. I can confirm that files get corrupt, when copy "file.txt" to "file1.txt" file1.txt will be corrupted and a large part gets cut off at the top. If the file is small it will result in a 0 byte file. |

Will have to reduce the maximum number of files in those modes from 1000 to say 750 Was as a result of the "fix" for zero length files b13 should solve this |

@Peter, The 2040 test version also solves the problems (file copy problem, and framebuffer merge problem) for the 2040 Game*Mite. Volhout PicomiteVGA PETSCII ROBOTS |

@Peter, Will you also update the other (VGA/HDMI) b12 versions with this fix ? Volhout PicomiteVGA PETSCII ROBOTS |

V6.01.00b13 PicoMiteV6.01.00b13.zip Fixes the zero length file bug WITHOUT bu....ing anything else (I hope) New experimental drivers for the SSD1963 (WIP) |

@Peter, Can you share more info regarding the SSD1963 drivers as very curious….. |

Hi Peter, is it the desired behavior that an entry in the command line - after running a program with `Option Explicit` - produces an error message about an undeclared variable? I would have expected the lifetime of `Option Explicit` to be limited to the program itself. (V6.01.00b5e) Kind regards Michael causality ≠ correlation ≠ coincidence |

Has always been this way AFAIK |
||||
| twofingers Guru Joined: 02/06/2014 Location: GermanyPosts: 1640 |
Thanks! Okay, so that means that to disable "Option Explicit" on the command line, I have to start a program that doesn't contain "Option Explicit"? From manual p91: This option is disabled by default when a program is run. causality ≠ correlation ≠ coincidence |

If i recall correctly, I encountered this behavior, and "new" at the command line undid OPTION EXPLICIT. Of course, you lose your variable values, but you also would if you started a new program. ~ Edited 2025-09-21 03:26 by lizby PicoMite, Armmite F4, SensorKits, MMBasic Hardware, Games, etc. on fruitoftheshed |

@matherp In the MMInKey() function in the PicoMite.c file, there is this non-sensical code. It doesn't hurt anything, but it can't ever be true. Perhaps it should be || instead of && ? if (c < '1' && c > '6') { c1 = '['; c2 = c; return 0x1b; } // the 3rd char must be in this range Edited 2025-09-21 07:45 by EDNEDN |

Peter, B13 seems pretty good. I have hoever one thingI havenot been able to quantify. For picofrog, I toy around with sprites, that occasionally are shown outside the lcd screen when I make a mistake. I remember this was very robust, but in b13, the pico crashes. White screen, no console. Is anything changed in the protection of screen coordinates? Or is my memory false. This is on 2040 game mite. I have not found a simple way to reproduce yet.

It shouldn't crash but it should error. Can you create a simple test program so I can investigate? Hmmm... Edited 2025-09-22 02:47 by matherp |

@Peter - I am using one of your RP2350B DIL modules (with b13 firmware) connected to one of the latest batch of 5” IPS panels arrived form BuyDisplay (exactly the same module you link to on your PicoPalm thread). Using 8-bit data connection. The issue I am seeing is a reversal of the Red and the Blue colours (green is ok). OPTION LCDPANEL SSD1963_5,L,,,,GP1 is set. Using GP13-GP16 for D/C, WR, RD, RST. Note option 5A does not work (splits the screen), and other sizes tried too without success. Everything else works as expected. Is there some kind of ‘undocumented invert’ parameter to resolve this issue in a similar manner as on the SPI screens? Also FYI, lots of time was lost attempting to use GP40-GP47 for the 8-bit data link (and using GP40 as the last parameter in the OPTION). It did not work - several DILs used, and three sets of wiring for each and all failed; only worked when I moved to GP1-GP8. Could there be a bug when using high PIN numbers? Also - tried on 6.0..3 and same issue with blue and red colours reversed. |

@Peter - I did see this in the manual regarding 16-bit mode, but I was ideally needing to use 8-bit mode. Are you saying the red and blue will switch round with the 5ER_16 (and that I can’t therefore use 8-bit comms)? I would try it but I’m away from PicoMite until this evening so curiosity has got to me…. Could there be a 12 bit mode too as you’ve eluded to in b13 (for the ER I mean)? Be useful to know so I can save some pins!! Edited 2025-09-22 15:04 by WhiteWizzard |

You can use POKE DISPLAY to change the colour order after the display is initialised when there is not a specific config for it. see this this thread F4 H7FotSF4xGT |

V6.01.00b14 PicoMiteV6.01.00b14.zip Fixes a couple of types in PIO Fixes a typo in reading escape sequences# WhiteWizzard Only the 16-bit drivers support changing the SSD data pins. There is quite a lot of overhead in processing this and with 3 transfers per pixel for 8-bit mode that would slow things down too much. The release does include 3 buffered drivers for the 5" BuyDisplay IPS display on the RP2350 BUT they are all 400x240 resolution. They do allow the data pins to be assigned as the updates take place on the 2nd processor. Feel free to try them. SSD1963_5_BUFF, SSD1963_5_12BUFF and SSD1963_5_16BUFF. Parameters are as per the manual |

@Peter - Thanks for explaining, although FYI, I do have remapped 8-bit data working when DB0-DB7 are assigned to GP1-GP8 (since GP0 is used for the PSRAM CS on your DIL module). VERY HAPPY with the massive improvement over 8-bit speed when using 16-bit comms set with OPTION ....5ER_16,L,,GP17,,GP1 Can confirm too the Red/Blue are sorted too making the colours in the EDITOR look normal once again! Thanks for the heads up on the 12-bit buffer; will try that on another unit later.........  |

If you are talking about serial, an observation on 2350VGA: Since long ago, scrolling in the editor in a long program leaves sometimes rests of escape sequences like "[" or "~" from the cursor keys. This only happens beyond the first let's say 40Kb. The scrolling slows down and immediately these errors occur. Sometimes it crashed the Pico and hard reset is necessary. And if a program executes an inkey$ command and looks for e.g. chr$(129) like the FM then it crashed for me fore sure. With b13 this is gone for all directions of the cursor keys! For the first time since half a year. Only Page Up/down leaves a "~" With b14 it came back. I reverted to b13 and it's fine again. I'm using as well inkey$ and even stressing serial by accidentally uploading a program while the basic program is running doesn't crash it. I've used b13 now two days intensively and found, that it runs best since long > option list PicoMiteVGA MMBasic RP2350B Edition V6.01.00b13 OPTION FLASH SIZE 16777216 OPTION COLOURCODE ON OPTION KEYBOARD US OPTION PICO OFF OPTION RESOLUTION 800x600 @ 360000KHz OPTION DISPLAY 50, 100 OPTION SDCARD GP24, GP25, GP26, GP27 OPTION VGA PINS GP32,GP34 Saying it "crashes" it is maybe too much but it doesn't respond anymore Edited 2025-09-23 05:17 by dddns |
