Thanks Peter, that sounds workable. However if it were my show I would have DEVICE(GAMEPAD ...) return -1 if not connected to a gamepad so as to distinguish between that and "no buttons down". YMMV, Tom Game*Mite, CMM2 Welcome Tape, Creaky old text adventures |

The boards have arrived and everything works perfectly  All the design files for the PCB are on https://github.com/UKTailwind/PicoMiteVGAUSB just upload to JLC and get some made!    Edited 2024-02-08 21:31 by matherp |

Thanks Peter. In the hopes of learning something can I ask why you chose to use different pins for the VGA than on the PicoMite VGA ? Best wishes, Tom Game*Mite, CMM2 Welcome Tape, Creaky old text adventures |

Because I can use all 30 pins I'm allocating two pins that are normally unavailable on the Pico for VGA. The other normally unavailable pin is GP29 which is an extra ADC pin so I have left this in the general pool. It just means there are more of the "normal" Pico pins available for general use. Just to confirm the spec: RP2040 16Mb Flash memory VGA Line level audio output jack Stereo PAM8302 amps and speaker connectors DS3231 RTC with CR2032 battery backup Support for USB keyboard, mice, and PS3, PS4, and SNES/Generic gamepads. All Pico GPIO pin broken out + GP29 CH340C to provide serial console on GP8,GP9 Edited 2024-02-08 21:52 by matherp |

Hello Peter, very good news. Since I am one of the chosen ones, please let me know how I should transfer the money. I can accept Paypal or bank transfers... Please send me a PM THX Dietmar |

I'm uncertain of the ordering process for completed boards. I uploaded the gerbers and got the $2.00 for 5 bare PCBs--as I've done many times before. I clicked on "PCB Assembly"--that added $8 for "Setup" and $1.50 for "Stencil"--and nothing for "Components". This comes to a total of $11.50USD for 5 boards excluding shipping. This doesn't seem possible to me, but I don't see what further I should do. Also, if it doesn't include components, I don't understand what it provides over the $2 option.

Ok, thank you. After "Next", I clicked on Bill of Materials (BOM) and Pick and Place. Cheapest untracked shipping was only $2 less than DHL, so I went with tracked and fast. This did not include the 2x20 header, but I have those in various configurations--male and female, right angle and straight, shrouded and un-. Total for 5 PCBs was $119.23USD after a $9 "SMD" coupon discount. I will probably be looking to sell three of them--buyers in the U.S., Canada, or Mexico--at cost, so $24 + shipping rounded up to the nearest dollar. Interesting to note that the DS3231s cost nearly 3 times as much as the RP2040s--$14+ for 5 as opposed to $5+ for 5. ~ Edited 2024-02-09 01:34 by lizby PicoMite, Armmite F4, SensorKits, MMBasic Hardware, Games, etc. on fruitoftheshed |

Remember when you receive them you will program them through the USB-A keyboard connector and you will need a male-male A-A cable |

I've designed a simple 3D printable box for the PCB. STL file is on github. If you haven't got a £D printer, just upload the stl to JLC and let them print it for you.     |

I've designed a box made from an A5 sheet of 2mm ABS and a A6 sheet of 3mm acrylic. We'll see how it works out. :) I like that one though. Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

Sorry Peter, I have only just read this request this morning, I don't know how I missed it but I saw many after your post. I added the 2 x 15k resistors as requested but the Hubs that don't work still don't. There appears to be a minor difference as most times when a k/b or mouse is plugged into the hub we get the following error Error Invalid address - Resetting However, very occasionally I can get a mouse or keyboard to plug in and be acknowledged correctly. Any subsequent device will report the above error and reset. I was never able (or never saw) to get any successful report prior to the 15k resistors. Do you want me to try pull ups or up and downs?

Peter, when will you send the Boards? |

He'll probably send them, once he's had a chance to breathe in again.....   Smoke makes things work. When the smoke gets out, it stops! |

Schematic PDF is corrupted?  I get that message, when I try to open the PDF from the github download. You can ignore the PM VGA manual PDF showing in the background. I will order some of these to play with.  EDIT: Can't open the gerber zip either. Windoze says the zip is invalid. 7zip says: "Errors: Is not an archive." Has anyone else been able to download the files from the github link without issue? Edited 2024-02-15 13:21 by Grogster Smoke makes things work. When the smoke gets out, it stops! |
