Hello, First message. New to everything. Unfortunately, I Found no answers for my issue with search. I bought and built the VGA PicoMite (https://www.siliconchip.com.au/Shop/20/6417?show_parts_list=1). It turned out very nice. I had hoped I could use VGA to HDMI converter cable to connect to my TV, but that didn't work, so I dug up an old VGA monitor. But that's not my primary concern at the moment. I would like to be able to run a web server on the PicoMite, but the OPTIONS and WEB commands seem to be missing from the PicoMiteVGA.uf2 firmware. Is there a solution for this please? Many Thanks.  |

You can't have VGA on the Webmite. There isn't enough memory to do it. The point of the Webmite is that it produces a web site that you can connect to using a PC, tablet or phone so there is no need for a display. The Webmite firmware only runs on the Pico W, not the ordinary Pico. To get info on using the Webmite you need the manual for it.

Thank you for such kind and quick responses. I've used the WebMite on a Pico W and connected via Mac Terminal easily enough. I could never get the web server to work though. I'll pursue that more in the future. I was just so enamored of the simplicity and 80s feel of the VGA PicoMite, and was disappointed to find that the web server option was not available. I understand the memory space issue though, I guess. Bummer. Could the web functions be added as libraries?  |

Am I to understand from your post that the editor can be routed to a web IP?? I was able to connect the WebMite to my SSD and get an IP address. But when I tried to connect with the browser, I just got a blank grey page. Odd that it was grey. But no text or other functionality. I even used different browsers since my daily driver, Firefox has all kinds of plug-ins and such. Still, no go. I was also able to get Telnet working, but it was slow, so I reverted to the screen and cu commands which were much more responsive.  |

Did you have a program running on the WebMite which would serve a web page? There is no default web page--you have to build what you want. PicoMite, Armmite F4, SensorKits, MMBasic Hardware, Games, etc. on fruitoftheshed |

Ah! I LITERALLY just got it to work and was about to write this message when I got the notification of your response. Indeed, I was under the impression that the INDEX.HTML file on the Pico when connected as a USB device for firmware flashing was the file the example program in the manual was trying to display, but I had no luck with that at all. I finally just created a simple HTML file and saved it to the A: drive called mypage.html and changed the name in the code. Worked a treat. Is it possible to access the directory where I found that INDEX.HTM files? I thought the manual said that was the A: drive, but my mypage.html file didn't go there. |

The Pico can only directly access files in two places:- A: which is created in it's flash memory. B: an SD card attached to the WebMite or PicoMite and configured in OPTIONs. INDEX.HTML has to be transferred to the Pico first. The easiest way is to copy it to an SD card then plug that into the Pico and copy to A: If you don't have a suitable SD module (one without a voltage regulator or level shifter) header pins (or wires) can be soldered to a MicroSD-to-SD adapter. As these are often supplied free with MicroSD cards you may have one spare.

Clever. I would never have thought to use an adapter as a MicroSD reader. Thanks. |

Welcome to the forums. Due to the VAST interest in the RP2040 chip, it is POSSIBLE that Raspberry Pi Org MIGHT release a new silicon with more memory etc, that would allow for a VGA Webmite, but that is only a maybe at this time. As of right now, it is either VGA-mite or Webmite(or standard Pico-mite) - C'est La Vie.... Smoke makes things work. When the smoke gets out, it stops! |

I tried connecting a VGA to HDMI converter cable to connect to the TV. It didn't work. So, I tried creating an HDMI connection from this video: https://www.youtube.com/watch?v=GyZS_efRyiY No luck there either. |

They couldn't be added in any way because the Pico W has extra hardware (Infineon CYW43439 etc) to do the WiFi / BT stuff. That hardware is not there in the Pico. However... using a WebMite (Pico W) together with a PicoMiteVGA would be quite easy - just have them talk to each other (COM ports or whatever). John Edited 2023-10-17 16:53 by JohnS |

You need the chip, no doubt. What I SHOULD have said was, "Is it possible to add the functions as a library on the WebPico?" But now you have me intrigued with the prospect of connecting the WebMite to a PicoMiteVGA via COM. I envy your experience to be able to say how easy it would be. I wouldn't have the first clue how to start. |

You can connect a Webmite to a PC via its USB console. You can then, if you are happy with entering html by hand, use the internal editor to create index.html by simply entering: EDIT "index.html You can then enter whatever you like and save it. By default it will go to drive A: Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

Thanks for the link. Sadly, I can't justify spending $99. Sorry, I don't understand your three points. Can you elaborate please? |

David VGA to HDMI converter cable is wire only do not work ! https://www.youtube.com/watch?v=GyZS_efRyiY that is not 'PicoMite' Basic firmware 'PicoMiteVGA' has fixed VGA pin`s Wayne !!! `ps Putty will Telnet set keyboard to ' The Backspace key ' Control-H ' ' unset Telnet ' Return key sends Telnet New Line instead of ^M ' ` Edited 2023-10-17 18:43 by amigawizard |

Wayne's comments are regarding that add-on board. It can't be driven from MMBasic. The Webmite firmware doesn't contain display drivers because it doesn't need them. :) It is simply a serves on the network. The console connection (via a terminal emulator such as Tera Term connected to USB) is independent and will work anyway, but it's only a console. This is the same system for all MMBasic platforms. This is probably the connection you would normally use for programming, not the web interface. Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

I see. Thank you Wayne, Mick. Much appreciated. I have found it fairly straight forward to Telnet to the WebMite and TFTP to send and receive files quickly and easily. I wish Telnet was a bit quicker though. Still looking into that. |

The WebMite has a full selection of TFT display drivers - just not VGA. Please be careful to check what you write particularly when responding to newcomers |
