I am playing around with my PicoMite VGA and wrote some test code but when I ran it I got the above error. Ctr-C stops the program but I can't edit or type. Short of reflashing is there anything I can do. Edited 2022-05-07 07:56 by palcal "It is better to be ignorant and ask a stupid question than to be plain Stupid and not ask at all" |

Maybe post the code. John |

Well I can't get the exact code the Pico is bricked. But it was just simple code to draw a circle and box and some text. Maybe I accidentally put in a value for x,y that was out of limits ? Edit... A list of Error codes and their meaning would be helpful. Edited 2022-05-07 08:13 by palcal "It is better to be ignorant and ask a stupid question than to be plain Stupid and not ask at all" |

Decided to reflash the Pico but the code stayed in flash and because Autorun is set I still have the same problem. "It is better to be ignorant and ask a stupid question than to be plain Stupid and not ask at all" |

Problem solved, I RTFM. Downloaded the Clear Flash file from Geoff's web site and the Pico is now back to factory so I'll start again. Unfortunately I will never know what the problem was. "It is better to be ignorant and ask a stupid question than to be plain Stupid and not ask at all" |

Now another problem, What is wrong here. I haven't used the COLOUR command to set backgroung and foreground. Edited 2022-05-07 09:32 by palcal "It is better to be ignorant and ask a stupid question than to be plain Stupid and not ask at all" |

A number of us have learned the hard way that autorun can be a Dangerous Thing and not to be touched until perfection is achieved! ;-) |

Thanks I will remember that, it's not the first time I have had a problem with it. "It is better to be ignorant and ask a stupid question than to be plain Stupid and not ask at all" |

In my problem with the colours if I change the Cyan to Black it works. Edited 2022-05-07 11:27 by palcal "It is better to be ignorant and ask a stupid question than to be plain Stupid and not ask at all" |

With the Colour PicoMite, I know there is a reason for this situation, but I forget what it is. I will have to have a hunt around to find out. Peter Mather released a code that allowed 640x480 colour VGA with some clever background manipulation, but there were limits to how you could use this, and I think that might be where you are stuck. Please tell us the resolution you are in: ? MM.HRES,MM.VRES The first standard 16-colour VGA mode is limited to 320 x 240. If you are getting a reply to the above query command of 600 x 480, then you are in one of the MODE options for OPTION COLOUR VGA ON. I need to look this up again, but I am pretty sure this is the kind of message you get, if you are in the crafty 640 x 480 VGA mode that Peter came up with. I'll post back here with a link once I find the thread I am thinking about. EDIT: Found it. Have a look at this thread. By default, the new firmwares default to MODE 1 so it would seem. From the console, issue the command: MODE 2, and it will switch to the standard resolution of 320x240, then you won't get the error. Edited 2022-05-07 16:52 by Grogster Smoke makes things work. When the smoke gets out, it stops! |

If you are in 640x480 mode 1 then the screen is effectively monochrome. Therefore colours can be only black or not-black. Your command sets the text foreground and background both to "not-black". |

Peter - I have been thinking about this, and Mick is not the only one to be caught by this situation. Would it be worthwhile changing the error message? "Foreground and Background colours are the same" is VERY confusing to most people, who will look at the code and say: No they're not! One is Yellow, the other is Cyan - that's not the same! I only mention it, as it has tripped up a few people now, so perhaps something along the lines of: "PicoMite is in MODE 1. Colours can only be black or not-black. Use MODE 2, or see the manual." Something like that? Smoke makes things work. When the smoke gets out, it stops! |

how about "Either Foreground OR Background colour must be Black"? cheers, rob :-) |
