Mint 21, latest Firefox - initial screen comes up, tick boxes active but no response to serial device (ACM0 115200) No indication of how to set specific/dev/tty device. Had a look at the source html and can not see any linkage to USB pseudo port - maybe it needs to be opened under chrome which may understand the ' terminal' command near the bottom? Doug. ... almost all of the Maximites, the MicromMites, the MM Extremes, the ArmMites, the PicoMite and loving it! |

Tried it with Opera browser on W10 and it seems ok. When you click on 'Connect' it shows serial device list (inc serial over USB) Select one, click connect and the Pico is there. |

If I understand correctly, you want to use vga picomite with a vga monitor and the keyboard that is attached to your PI4. You can.... Sudo apt-get install putty. Open putty, select serial Port = /dev/ttyACM0 Daudrate dont care, but set to 38400. Plug in picomite. Connect. You will have terminal on PI4 and on VGA, and the keyboard from the PI4 is used. Save the config, named picomit There will be some settings you might like to change. I.e. delete=ctrl-h, line ending=cr. That is it.

Works fine for me - except the backspace character is wrong. This came up before -- see this thread: here Re the above thread -- I gave up eventually and went for terminal software running from USB. N Entropy is not what it used to be |

Thank You Volhout , I get the terminal , but cannot make the editor usable . It acts pretty much the same way on different terminal programs ( including the online one ) I am evedently missing something  my site |

In what way isn't the editor usable? It normally works fine if you can connect to it at all. Is it sending the sign-on message? If you can't send it commands then check the CR & LF settings. Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

With so many different terminal programs having the same problem, the issue must be the OS failing to give access to the port. Is the OS missing a necessary module or just need configuring? Are the security settings blocking access? Is there another computer you can try it on? Edited 2023-03-06 08:22 by phil99 |

If I get to where I can type in a line of code , it disappears when I hit ENTER my site |

It would tell you if the problem is with the PI or the Pico. Anyway I missed the bit about "OPTIONS LIST gives message". That shows you do have the terminal working so ignore my other ramblings. It shows you are in "Immediate Mode" Type PRINT MM.VER and you should see the version number on the terminal and VGA screen. Type PRINT "Hello World" likewise To enter the editor type EDIT The "Using MMBasic" chapter in the manual describes the use of the editor. |

I have not encountered that. After typing EDIT<enter> do you see a list of the shortcut keys along the bottom of the editor window? With the scope do you see activity on the sync and video pins of the Pico and VGA socket? As long as there is something showing in the terminal window there should be video activity. About 3V peak at the Pico pin and about 0.7V at the VGA socket. Typing CLS RGB(White)<enter> should produce 3V on all 4 Pico video pins and fill the VGA screen with, in your case, green.

For an unknown reason the editor seems to go straight into insert mode. ESC should get you back to text entry mode, with this at the bottom. ESC:Exit F1:Save F2:Run F3:Find F4:Mark F5:Paste Ln: 1 Col: 1 INS Then you should be able to type in a program. F2 will save it, exit the editor and run it. Then again perhaps your terminal window is way too small and just showing the bottom right of the editor window. Now I think about it Insert mode is text entry mode, so the window must be too small or the Font too big. Does your terminal program have adjustments for those settings? If not can it be done through the OS GUI settings? Once again worth testing the Pico with TeraTerm on W10. Its default is to adjust the terminal window to match the editor window. When you have it sorted out there and can run a short test prog. back to the PI to get that sorted. Edited 2023-03-06 17:06 by phil99 |

My current settings (for a PicoMite VGA) are: In Tera Term Terminal is 120x40 (I run it in a window) Term size = win size New line on Recieve CR New line on Transmit CR Terminal ID VT100 Font Lucidia Console Regular 14pt On the PicoMite VGA no additional settings required, but on the non-VGA version you may need to set OPTION DISPLAY to match the terminal. The VGA display is what it is. Any changes are due to your monitor. Edited 2023-03-06 18:22 by Mixtel90 Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

Hi hitsware, I can imagine that you are in dispair that it does not work. As far as I understand, the terminal works for direct command entry, but the VGA screen does not show any picture. Correct ? I hope you don't mind asking me stupid questions: 1/ print mm.device$ does it say "PicoMiteVGA" 2/ we discussed simplest VGA connection. Did you use a single resistor, or 4 resistors ? Please use 4 resistors and does it make a difference ? Maybe the one color you connected hides the real problem with the VGA screen. 3/ please type "OPTION RESET", this removes all unwanted settings from the options menu. Does this help ? 4/ Have you installed Putty on raspberry pi ? Putty terminal will default follow the screen resolution of the picomite, and will always give an adapted screen resolution. So nothing is hidden. 5/ understand that the serial terminal does not show any graphics, only the VGA does. 6/ The terminal program should be set to emulate VT100. If you have it set to ASCII, then the editor will not work (VT100 has codes to move the cursor around the screen, and color text....ASCII does not). 7/ when all works except backspace/delete, then change the character from ESC code to ctrl-H. 8/ in command mode F4 will open the editor. In the editor F4 will go into MARK mode. It seems characters are send twice. Do you have ECHO ON ? Volhout Edited 2023-03-07 06:34 by Volhout PicomiteVGA PETSCII ROBOTS |
