 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. |

A new beta version of the Micromite firmware V5.05.02 (Beta 1) is available for anyone who would like to play with it. This can downloaded from: http://geoffg.net/micromite.html Look for "Micromite Firmware V5.05.02 Beta Test Version" at the bottom of the page. Apart from a couple of minor changes the main feature of this release is the ability to trigger an interrupt on a serial port when a certain character has been received. The number used in the fifth field in the comspec string can now be prefixed with an equals character (=) and in that case MMBasic will call the interrupt subroutine when a character with that ASCII value has been received (rather than a certain number of characters). There was some discussion on this forum as to if this feature was really necessary however in testing I have found it quite useful. For example, I had an application where interrupts were needed to get a line from a GPS module. Previously an interrupt was required on each character, now only one interrupt is needed when a carriage return character is received. The idea of the beta versions is to test new features and bug fixes that have the potential break something else within the interpreter. I will keep updating the beta version until it is stable and then make it into a final release. If you find any issues or bugs in this beta please report them in this thread and I will try to fix them ASAP. Thanks Geoff Geoff Graham - http://geoffg.net |

Thanks Geoff, I see you have also changed the CLOSE command to wait until the last character has been sent before closing the port. Does it wait until it has actually been sent or until the buffer is empty? Also, do you plan the same update for the DOS version? Bill Keep safe. Live long and prosper. |

It actually waits for the last character to be clocked out of the hardware UART. So nothing will be lost. No. In the Windows/DOS version writes are not buffered so any command that writes to a serial port will only return when all the data has been sent. There may be one last character being clocked out of the hardware UART but a CLOSE should not disturb it. Geoff Graham - http://geoffg.net |

Hi Geoff, Thanks for the ability to trigger the interrupt on a specific received character value. It appears to be working as expected. So far I have only done a fairly simple test, using an ETX character (CHR$(3)) as the End Sentinel and it correctly detected the end of every message I threw at it with just the one interrupt per message. I will test further as soon as time permits. Phil. |

Can the long string functions be added to the DOS version? PicoMite, Armmite F4, SensorKits, MMBasic Hardware, Games, etc. on fruitoftheshed |

They could be. The other option is to increase the default size of strings to 1K or even 2K (there is plenty of memory on a PC). I will look at both options. Geoff Graham - http://geoffg.net |

Thanks for looking. On the Pi-cromite I'm currently reading in an HTML template file which is 6K long. I'd like to run basically the same code (without i/o, of course) on mmbasic DOS. PicoMite, Armmite F4, SensorKits, MMBasic Hardware, Games, etc. on fruitoftheshed |

lizby: It would be very easy for you to add my longstring commands to your own version of MMBasic for DOS. Download Geoff's source and get yourself set up to compile/link it. Then download the MMX source. Once you have got this working I can provide very simple instructions as to how to copy/paste them across - no coding needed.  |

matherp--that's a very generous and tempting offer to get myself familiar with the process. I will put that somewhat high up on my to-do list--if the offer remains open. Copy and paste would be good for starters--I have written a lot of C code, but that was mostly over 30 years ago, so I'm rusty. Can still read it pretty well unless it's hard-core C++. Are there instructions somewhere on the compile/link process for the DOS mmbasic code under Windows. Meanwhile, upon reflection overnight, I realized that I can easily enough rewrite my code to just read the HTML template file whenever there is a need to update--on a PC, any delay in execution is not likely to be noticeable. Thanks for consideration and suggestions. PicoMite, Armmite F4, SensorKits, MMBasic Hardware, Games, etc. on fruitoftheshed |

how many different variants on mmbasic would that leave us with? i am just a little concerned that the language may be fragmenting. it seems that we now have, with differing abilities and features the following hardware: MX170, MX470, MZ, ST micro, RPi. core features that vary are: single/double precision, long/short strings, other things??? does a chart exist detailing this all yet? one option (no pun intended) would be for the interpreter to default to regular strings, then have a (non-permanent) OPTION LONGSTRING ON|OFF. the same could perhaps be done for single/double precision. this would at least mean default behaviour would be consistent, and any program that used long strings or double precision would throw an error if not supported. note: this idea may be impractical due to the flash overhead of supporting both sets of routines. cheers, rob :-) |

Its not such an issue: All versions are double precision except the basic MM2 All versions use normal strings, my versions have Geoff's longstring CFunctions embedded as separate additional built in commands/functions All versions support core MMBasic using identical code Additional capabilities and any other differences are identified in add on manuals, MM+, Pi-cromite, MMX, Armmite H7, Armmite L4 (to be written) My proposal to lizby was simply that he builds himself, for his own usage only, a version of MMBasic for DOS with the LONGSTRING commands and functions added, something that Geoff's architecture makes trivial to inplement |

@Peter: In your (I think last manual) "2018-11-29_210840_Micromite_eXtreme_Manual.pdf" on page 6 you can read that the Micromite Plus has only single Floating Point Precision... - that irritated me a little...  Frank |

Are you easily irritated? The MM+ was single precision until a very recent release - I am really really sorry that I didn't update the MMX manual with this change - sorry , sorry, sorry!!!! |

Hi Peter, Where can one find the latest documentation etc. on the Micromite Extreme? Maybe the Document Register would be a good place? Bill PS Don't be too offended, English is not Frank's first language. Keep safe. Live long and prosper. |

Thanks Jim, Peter's work is too valuable to be sprinkled through the forum and too hard to find even when you know its there. As is yours, TimeLord and FontTweak are two that I have found (not to mention MMEdit). I think they should be in the Document Register. If you and Peter don't have the ability to put stuff in there then maybe Gizmo could give it to you. Thank you both. Gizmo? Bill Keep safe. Live long and prosper. |

Excuse me, Peter, I really didn't mean to attack you with this!!!! What you did is phenomenal and creating the documentation is really a lot of work! That the events can overtake the documentation is only natural! I was only recently looking for a platform with double Precision and was no longer sure if the Micromite Plus really supports this... It really wasn't an attack on you and I really appreciate your work!!!!! I hope you didn't misunderstand me!!! If you do, I want to apologize to you!  Frank |

Is it reasonably possible, and would it make sense, to have an MM.LINENO variable which would return the current line number, so that you could, for instance, log info with an indication of what line number you are on, e.g.? PRINT MM.LINENO;" variable A now has value of "+A I sometimes hard code line numbers, but, of course, they shift. PicoMite, Armmite F4, SensorKits, MMBasic Hardware, Games, etc. on fruitoftheshed |
