 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. |

Unfortunately Anthony (in this thread ) found a bug in the handling of the internal flash drive A: in 2.7. It shows up as four lost bytes for every 4076 bytes written to a file. This was sufficiently important to put out an immediate fix (ver 2.7A) which you can download from http://geoffg.net/maximite.html. The updated source code can be found at the same location. This release also fixes a couple of other bugs and adds one feature (details in the change log). A matching release for the UBW32 is available from http://geoffg.net/ubw32.html. Don't forget to backup your drive A: before installing the update as it will clear that drive. Apologies for the messing around, Geoff Geoff Graham - http://geoffg.net |

Damn, there was a bug in that version related to composite video. If you have downloaded it please do it again - the version now there fixes it. Geoff Geoff Graham - http://geoffg.net |

No sparkey, I did not change anything in that area. I was in too much of a panic to get this fix out. I will look at it later. Geoff Geoff Graham - http://geoffg.net |

Geoff, Sorry for the panic! The 4K bug certainly got my attention/curiosity when testing the copy program and seeing the small change in file size. Cheers, Anthony |

A very minor update to the Quick Reference is available - essentially this just includes the features added in 2.7A which are OPTION USB and OPTION VIDEO. |

Hi everyone I have just joined the forum and apologise if I am in the wrong place for my question. I have just upgraded to Version 2.7A, but have not been able to figure out how drive A: is accessed. Anything I do seems to point to the SD card, but I cannot work out how one switches from drive B: to A: or vice versa, or what is the indication what drive you are using. Can"option prompt " be set to indicate the drive letter as in old-fashioned DOS ? I am relying here on the old saying that the only stupid question is the one that was not asked, LOL  |

@arvindk, try the following for something like the good "Old Fashioned DOS" prompt: [code]OPTION PROMPT MM.DRIVE$+CWD$+">"[/code] Which will give you the something like: [code]A:\MYDIR>[/code] ...or even more useful, you can include the current file name you are editing (since SAVE, RUN, etc work against this from v2.6 onwards): [code]OPTION PROMPT MM.DRIVE$+CWD$+"\"+MM.FNAME$+">"[/code] Which will give you something like: [code]B:\GROOVY\STUFF.BAS>[/code] You could go nuts and inlcude TIME$, DATE$, or whatever, but it starts to eat into the available line space... You can include the above in your AUTORUN.BAS. Cheers... |

Thanks to all for your help. I do feel sorry that I did not follow the age-old advice of RTFM !! 
Although mm.drive$ is listed in the manual, I would not have known that 'drive' was a valid command and needs to be followed by a string (with the drive letter). I do not remember this from my GW-Basic days. I find the Maximite a great little tool and the forum matches it. Great job Geoff and all of you senior members. I also have a UBW32 from Sparkfun and will load Maximite version of MMBASIC into it today. I rather like its 50-pin capability. Back to work now |
