 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

PicoMiteRP2040USB doesn't have a Console accessible on the USB port once it has started running. It's no use looking for one 'cos it doesn't exist. :) You *have* to swap over to a serial Console to even see anything as there is no display configured at this stage! If it's not connected to GP8/GP9 then it gets awkward, so don't even consider that until everything works ok. You can get a serial console connection by using a USB-TTL converter or by using a hardware serial port on something. In either case it has to be 115200 baud by default. As you say, Stan, the same USB cable that was used for programming the firmware can be used, providing it uses the same connector for the USB-TTL converter. I have a pile of USB cables that have little paper labels on them now, Volhout. "NO DATA". Most cheap electronics seems to come with that sort now. :( Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

Maybe a little bit of confusion above but to clarify. I have a basic raspberry pi RP2040. I have used these many times over the last few years without real issue. I have eliminated my USB cable and hub as the results are the same if I change to a direct USB and a different cable. I have downloaded the updated firmware PicoMiteRP2040USBV6.00.03.uf2 as I use a USB keyboard and mouse and need to run touch LCD panels which I have also used extensively before. So as I see it, just as before, I have no need to bother with connecting to GPIO pins when loading and intialising the Pi. I should be able to just connect to the USB connector. I use MMEdit ver 5.2.9 rather than TeraTerm, although I am getting the same issues if I also try TeraTerm. I have discovered since my last post that I can get Com5 listed in my Device Manager, but only if I download PicoMiteRP2040VGAV6.00.03.uf2 ie the VGA version. But then it does not run the program and I will not be able to get the use of LCD touch panels! Is there something in the above that is not right? As I see it I am following all the instructions on P6 and P7 of the User Manual. Roy |

You are loading the USB software. THIS DOESN'T CREATE A CONSOLE ON THE USB!!! Either Load the normal software PICOMITEV6.00.03.uf2 Or Load PicoMiteRP2040USBV6.00.03.uf2 and connect an external USB/UART to GP8/GP9 The VGA software works because you are NOT loading the USB variant |

as said usb version once flashed the usb is usb kb... and usb mouse. you need usb to ttl converter wired to gp 8,9 and connect that usb to win pc and it should show . I then set mmedit to that port and press connect, then click flash button flashes code selected. the usb to ttl converter has 5V and 3.3V out pins and need to connect 5V to pin 40 vsys to power pico and usb kb OPTION SERIAL CONSOLE COM2,GP8,GP9 stan Edited 2025-07-27 03:59 by stanleyella |

Where do I find the PICOMITEV6.00.03.uf2 file? It is not included in the zip list or under the archive list. |
