 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. |

Sorry haven't got a test board with me for that build. Will have a look at it after Saturday next week. In the meantime use b1. Try downloading again, it may be better. The performance differs between builds based on tiny changes in the location of functions in memory and how they interact with caching from flash. No idea. You have to have downloaded TinyUSB 0.21 and have it in the correct place in your environment. There are also three patches that need to be applied to it. These are all in the github |

I think this has been reported, but to bo sure, B2 is having problems with USB on a 2040 VGA USB, Option CMM1.5 As soon as I plug in a USB keyboard I get the following. B1 is so far working fine.

b2 is a big change to a newer version of TinyUSB. This has one major advantage - much faster USB flash drive access but has been a pig to get reliable. I believe the RP2350 variants are all OK but the RP2040 VGA USB is definitely broken. I can't look at this until the end of next week as I don't have an rp2040 available at the moment. |

Peter, A added the RF module to your board (PiComputer 3). Then upgraded the firmware to PicoMiteHDMIWEB V60302b2. When running the profiler program profiler The code stops at test 9 (PLAY TONE command). Simply stops (need RESET). I re-installed PicoMiteHDMIUSB V60302b2 (the non WEB version). Then the profiler runs to the end (with the remark it did not test WIFI, since WIFI is not in the HDMIUSB build). EDIT: problem solved : R90 was not populated on this board. After adding a 470 ohm resistor all works fine. Volhout Edited 2026-09-08 00:15 by Volhout PicomiteVGA PETSCII ROBOTS |

Run perfectly for me - this is the version I was testing with tested with and without a USB keyboard, with and without wifi logged in PicoMiteHDMIWEBV6.03.02b2.zip |

Peter, Thanks for the response regarding V6.03.02b2. Version PicoMiteVGA MMBasic USB RP2040 Edition V6.03.02b1 works excellently following V6.03.00RC21, and all data was preserved. I look forward to the results of the investigation. Also, thanks for the firmware update command covering all versions; the issue with the `edit` command and the mouse-enabled banner in the terminal is now working perfectly in V6.03.02b1. There is another issue with PicoMite MMBasic USB RP2350A Edition V6.03.02b2. If I connect only a USB flash drive to the Raspberry Pi Pico 2's USB port and list the directories using `fm`, everything works fine. However, as soon as I try to copy multiple directories to A:, the firmware freezes. Copying small, individual files often still works. I also tested this with PicoMite MMBasic USB RP2350A Edition V6.03.02b1, and everything works as expected. I also tested it with an RP2350A0A4 with 16MB of flash memory; it failed there too, whereas the previous version (V6.03.02b1) worked correctly. *** FAULT PC=100BBED0 LR=100B55F7 SP=2007FE90 CFSR=00000000 HFSR=80000000 *** FAULT R0=00000001 R1=00000000 R2=200724D1 R3=FFFFFFFF R12=000000FF XPSR=09100000 FAR=FFFFFFFF EXC=FFFFFFFE9 > USB Flash Drive Connected (addr 1) > option list PicoMite MMBasic USB RP2350A Edition V6.03.02b2 OPTION SERIAL CONSOLE COM2,GP8,GP9 OPTION FLASH SIZE 4194304 OPTION COLOR CODE ON OPTION KEYBOARD US OPTION CPU SPEED (KHz) 200000 OPTION DISPLAY 50, 100 Jan. |

@Peter, is there a way to go to low baudrates with the com-ports? If I try to go to 300 Bd I get an error. > open "com3:300" as #1 > Error : 300 is invalid (valid is 343 to 921600) I know, 300Bd and below is a bit outdated, but if I want to connect some old equipment I may need it. At least the CH340 used for com3 (CDC) could do even lower. I'm not asking for 45.45 Bd for RTTY as then I also would need 5 bit character size. Maybe for CDC devices the limitation could be extended as I assume for com1/2 there may be a divider size issue. Btw: the manual says 1200 is the lower limit but the error message says 343 and this works. Maybe the manual should be corrected here. Tnx, Gerald 73 de OE1HGA, Gerald |

Memory can only be used once…. I started a port of STONED game to PiComputer3. Used MODE4, since that promised the best visuals for HDMI. Today I solderend the WIFI module, and upgraden to HDMIWEB version. But lost MODE 4 (not supported). Just a heats up for those who add WIFI, you loose Some video modes.

V6.03.01b3 is posted at https://github.com/UKTailwind/PicoMite/releases/tag/PicoMite-V6.03.02b3 Should fix any issues with rp2350 USB builds and reduces the memory footprint of the FM command. Please try the RP2040 VGAUSB build and report any diagnostics assuming it is still broken Note: the user manual has also had a significant update Edited 2026-09-08 03:20 by matherp |

Peter, The manual only indicates that web funtions take resources. But from the manual it is not clear that the MMBasic in the picomputer3 does not support mode 3,4 and probably also mode5 on the 640*480 resolution setting. To me that was a surprise. Is this temporary? Something that in b4 can be fixed? Or is the memory map fixed? I do like the usb memory device support. The fact that I can use USB mouse and kb. But web degrades the picomputer3 HDMI to VGA capabilitie…ok…palette is extra… And it is not so much the loss of the modes, but the fact that there are 2 different picomputers. And programs made for one version, Will not run on the other. Would be Nice if there is a clear plan on a common featureset. Maybe even remove funtionality (thi is a curve I know) to achieve this common set of features. Otherwise the community suffers. I released STONES in the understanding it would run on picomputer3, but since most install web, no one can. Volhout Edited 2026-09-08 05:01 by Volhout PicomiteVGA PETSCII ROBOTS |

Peter, Thanks for the new version, V6.03.02b3. I ran a few quick tests. The RP2350A seems stable, and I haven't encountered any further USB-related error messages. I haven't tested everything yet, though, so I'll provide an update later. I also tested the PicoMiteVGA MMBasic USB RP2040 Edition V6.03.02b3. There were no error messages; the USB keyboard is detected but only works intermittently, and the mouse doesn't work at all with this version. > Option MOUSE SENSITIVITY f!

Sometimes the keyboard works, but when I enter edit mode, the connection to the keyboard is lost without any notification, and I can only view the Pico via TeraTerm. When I exit Edit, there is still no response from the USB keyboard, and the mouse hasn't worked with this version yet. I'll continue testing tomorrow. Jan. |

Jan Please try the attached PicoMiteRP2040VGAUSBV6.03.02b3.zip Please then run the attached program and report the results ?"contend ";PEEK(WORD &H2003BD94) ?"switch ";PEEK(WORD &H2003BD9C) ?"declined ";PEEK(WORD &H2003BD98) ?"DATA_SEQ ";PEEK(SHORT &H2003BDA2) ?"BUFCTRL32";PEEK(SHORT &H2003BDA4) ?"BUFCTRL16";PEEK(SHORT &H2003BDA6) ?"total ";PEEK(SHORT &H2003D392) Run it at four points: 1. Right after boot, before plugging anything in — everything should read 0. If it doesn't, the addresses are wrong for their image and nothing else is worth reading. 2. Just after plugging the keyboard in, once it's enumerated (or failed to). 3. The moment the keyboard misbehaves — especially straight after the EDIT-mode loss, which is their most reproducible trigger. Read it before doing anything to recover. 4. With keyboard and mouse both connected, since the mouse never works at all and two devices are what actually create EP0 contention |

Peter, I performed the proposed test; here are the results. File extracted and loaded using Update Firmware. All existing data on A:/ and in the option list remained intact. Test file sent to MMEDIT and loaded onto the Pico. 1. Result of the first test. > run contend 0 switch 0 declined 0 DATA_SEQ 0 BUFCTRL32 0 BUFCTRL16 0 total 0 This was executed using Tera Term and was also visible on the VGA screen. 2. Result of the second test. > US USB Keyboard Connected on channel 1 > [USB DATA_SEQ 1] > run contend 0 switch 0 declined 0 DATA_SEQ 1 BUFCTRL32 0 BUFCTRL16 0 total 1 The USB keyboard works normally, and the mouse is still disabled. The VGA screen also works normally. 3. Result of the third test. On the USB keyboard: > EDIT; the keyboard then works normally in EDIT mode. Exit EDIT and RUN. > run contend 0 switch 0 declined 0 DATA_SEQ 1 BUFCTRL32 0 BUFCTRL16 0 total 1 So far, so good. We are now waiting at the > prompt. If I enable the mouse now, the USB keyboard becomes blocked. If I run the command in Tera Term, the result is as follows: > run contend 0 switch 0 declined 0 DATA_SEQ 1 BUFCTRL32 0 BUFCTRL16 0 total 1 4. This covers the fourth point as well. If I reset the Pico, the keyboard responds again. I repeated the same steps with EDIT, and as soon as I enable the mouse, it causes the keyboard to stop working. > run contend 0 switch 0 declined 0 DATA_SEQ 1 BUFCTRL32 0 BUFCTRL16 0 total 1 Tera Term listing from when the USB keyboard and mouse had stopped working.
