two things I've noticed so far. 1. GUI CALIBRATE stays foreverin the first page... Has anyone gotten this to work yet? 2. Playing "MOD" files is very, very quiet, so it's hardly noticeable. would it help to change R6 R7 27K with lower once? Edited 2023-10-03 19:43 by Martin H. 'no comment |

It works just fine on mine, I would check a different display if you have one, I've certainly had one with broken touch before now ... I assume your display does have touch, I believe it is U2 on the back of the display module ? Again it seems fine on mine, though a little quieter than the primitive PLAY SOUND I've used on the menus and in my games. I believe lowering those resistors could help. Does anyone else see these issues ? Best wishes, Tom Game*Mite, CMM2 Welcome Tape, Creaky old text adventures |

Hi Martin, Just tried screen calibration and it works fine, when you say "stays forever in the first page..." do you mean it never moves on when you press on the top Left target? If that is the case it sounds like your screen has a problem with the touch, could check the soldering of the screen connector, make sure you don't have a dry joint. You could also try doing the modification mentioned in the instructions, to short out the 3V3 regulator on the LCD, so that the screen gets the full 3v3 from the Game*Mite. I haven't tried MOD files yet, I seem to remember when you allocate memory to it, it reformats the A: drive, so any files there get lost? and I don't currenty want to do that, maybe when I do a full update. Almost sounds to me like the Left & Right channels are out of phase, so cancelling out, have you tried a few MOD files? Regards Kevin. Edited 2023-10-03 20:24 by Bleep |

Thank you Kevin I have never set up a touchscreen on the Pico, so I may have done something wrong. The crosshairs stay at the top left and he wants me to press and hold, but nothing happens. I tried this with 2 different displays so I'll probably have to check the soldering points I set up the MOD buffer without losing any files from A: -- you're thinking about phase cancellation between the right and left channels. That would be very unusual because MODs only have 4 channels. So rarely are 2 channels used that play the same waveform at the same Time. I've tested it with several MODs, so that would not be the reason. If I turn the pot on the small amplifier all the way to the right, it helps a little, but the difference between normal Play Sound and Play MOD is significant. Edited 2023-10-03 20:57 by Martin H.

Hi Martin, All, Re. The calibrate locking up. Firstly, try shorting out the solder pads on the TFT’s onboard regulator so there is no voltage drop to the touch controller chip. Secondly, it ‘could be’ the old MISO problem, you could try cutting the touch-miso pin off the TFT display Thirdly, check the option settings and make sure the touch options are set correctly.

Hi Martin, Try my CIRCLE game (few posts back). It plays a MOD file. Maybe the difference is in the content of the MOD file. Or did you set PLAY VOLUME low. Volhout Edited 2023-10-03 21:05 by Volhout PicomiteVGA PETSCII ROBOTS |

The new Game*Mite software image reserves 128kbyte for MODBUFFer. And the whole A:/ drive is pre-filled with sample games and menu software. Volhout PicomiteVGA PETSCII ROBOTS |

Last time I used touch, it required a "sharp" tip to activate the touch during calibrate. Nothing like what I am used to in operating my mobile phone. Diagnosis: doe the SD card work ? It shares lines with touch. Volhout Edited 2023-10-03 21:12 by Volhout PicomiteVGA PETSCII ROBOTS |

Hi All, As far as I know there hasn’t been any MISO issue with the ILI9341 TFT displays in the past so I doubt it is the issue. Mick Mick's uMite Stuff can be found >>> HERE (Kindly hosted by Dontronics) <<< |

Hi Tom, you are right .. the second display has no U2 (U1 in this case) so there will be no Touch at all.  But the 2.8 ' Display, which I connected first has it. But this one has a crack in the Display so it is possible, that touch is broken. I had already ordered a new one, so I'll try it when it arrives. Thanks for your support cheers Martin Edited 2023-10-03 21:26 by Martin H. 'no comment |

Correct. One of my reasons for creating the Game*Mite was to provide a standard I could write LCD games against, hence standard: - display resolution - controller I/O allocation - audio I/O allocation - OPTIONs The alternative being a PCB free-for-all, which enjoyable as it is, is a bit of a nightmare when it comes to writing software. A:/ drive is a bit too full at the moment so one of the things I am working on is combining/crunching the standard software. I'm updating my transpiler so it can tree-shake (delete uncalled subs and functions #INCLUDEd from my 'splib' library) and crunch identifiers. I imagine I can shrink everything by ~50%. @Volhout, I've just tried "Circle" for the first time, it's brilliant, and so simple, my girls are going to love it. I'm definitely (with your permission) going to add it to the standard software after titivating it a bit. One suggestion would be slightly more graduation in the growth of the "things". @Martin, the MOD included with "Circle" seems fine so I'm guessing there is some H/W issue with your Game*Mite, though what it can be given normal PLAY SOUND is working escapes me. How much rotation do you have on the volume control before PLAY SOUND is OK for you ? for me it is ~30%.

Hi Tom, very nice project! You wrote that a kit is available via ebay? I live in Germany and checked German as well as the UK ebay site and did not find it (searching for "Game*Mite"). Is there a way to get a kit to Germany? Thanks and best Thomas |

Thanks. I've just put another one up on eBay, you may have to wait a couple of hours until the listing propagates to international sites but then search for "Game*Mite". When Martin bought one, with taxes etc. it costs about 45 € from Germany. Personally I'm not convinced it is worth that much, but that's just how it works out if I sell it above board into the EU. Part of the issue is that eBay gives no option other than to use tracked international postage for it. @bigmik might be able to do better.

Yes, please adapt it to your liking. I am just happy someone likes it. The "growth" is quite exponential near the end, that is a fact. Could use some tweaking. But understand that when you are growing bigger, there is no chance of bypassing the opponent (shrinking again), so the game may never end when growth is too gradual.... Volhout B.T.W there is the original 2 player version for VGA.... Your girls can play against eachother using the VGA Game*Mite and 2 NES controllers. But that version is a lot older. If you want I can bring it up to level with this one (including turbo run). Edited 2023-10-03 22:07 by Volhout PicomiteVGA PETSCII ROBOTS |

Funny little Game,   the Mod is playing in a OK Volume when every Pot is turned to max.(the one on the AMP and the one on the Board.)I will test tomorrow to change both resistors to from 27k to 22k, I think that would be enough then. 'no comment |

I think there is something fishy in the audio train on your board. For the menu "beeps" how far do you need to have the thumb-wheel volume pot turned (the manual suggests the one on the PAM is always at max) ? for me about 30% is more than sufficient.

20% to hear the beeps quietly. 30-45% is sufficiently loud 'no comment |

Thanks. I found it and ordered it immediately  Yes, € 44.50 via PayPal. Well, no one can expect that you set up your international business just to serve us some costs. Thank you for all the time that you and @bigmik invested! Best Thomas |

Thank you, order received, it may not go in the post until Friday morning because I've run out of made up kits (but I do have all the bits) and need to find time to do a new batch. Best wishes, Tom Edited 2023-10-04 01:06 by thwill Game*Mite, CMM2 Welcome Tape, Creaky old text adventures |
