just had occasion to get a picomite set up to output VGA, and was pleasantly surprised at how easy it was. i did, however strike a small oddity when experimenting with OPTION LCDPANEL CONSOLE font it appears that if you select font #5 or #6, ie type: OPTION LCDPANEL CONSOLE 5 or OPTION LCDPANEL CONSOLE 6 you can not change the font again. the only thing that works is: OPTION RESET i suspect it is something to do with the VGA screen's width (with font #5 or #6 selected) being too narrow to allow entering the full command. but this is of little consolation when you get stuck! btw, i see that when VGA output is enabled OPTION DISPLAY lines [,chars] is disabled. it would be rather handy if, at least, OPTION DISPLAY lines was allowed, provided that the number of lines specified was less than or equal to the number of lines available on the VGA with the currently selected font. the editor could then be limited to just using the number of lines specified. useful when running both a 80x24 terminal emulator and VGA screen at the same time. a 8x16 font would also be rather handy, allowing a 80 column by 30 line display. an 8x20 font would allow 80x24. the reason: 40 lines is way too much on a tiny (7") 16:9 widescreen monitor. cheers, rob :-) |

It confuses me that you are using OPTION LCDPANEL CONSOLE when the output device is not an LCD but is a VGA display. |

The Option existed long before VGA output and was retained as it still does the same thing. OPTION LCDPANEL NOCONSOLE allows you to have OPTION DISPLAY lines [,chars]. OPTION RESET isn't too painful if you keep older .ODF files with standard Options. |

there appears (from the 5.07.07 manual) that there is no OPTION VGA .... i agree, OPTION LCDPANEL ... is both confusing and ungainly. but that can be said of much of OPTION ..., MM.INFO(...), and MM.INFO$(...). these commands and functions have been added to piecemeal over a number of years. i guess my main point is that, for a beginner, it is easy to type: OPTION LCDPANEL CONSOLE 5 or OPTION LCDPANEL CONSOLE 6 into your brand new picomite VGA, and if you don't know about OPTION RESET effectively brick it. especially true if you have already set up keyboard and sd card configuration which will all be cleared by OPTION RESET. simple solution would be to lock out fonts #5 and #6 from being selected at the prompt. or to bite the bullet and move all persistant options into a config.ini file on the internal flash drive. cheers, rob :-) Edited 2023-12-31 14:39 by robert.rozee |

why not just use Mode 1 and Mode 2 on PicomiteVGA without the options? I just use OPTION LCDPANEL NOCONSOLE, if I want to Monitor things via the Terminal without writing it to vgaMonitor. Edited 2023-12-31 18:18 by Martin H. 'no comment |

I've never found the need for OPTION LCDPANEL CONSOLE. All my crashes are good, well-behaved ones. ;) Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

Even then they can just load Clear_Flash.uf2 (Or ask on TBS...) John |
