 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. |
Forum Index : Microcontroller and PC projects : MMEDIT - copy file from MM to PC...

Can't get this to work. I can start MM chat, I can copy code from MMEDIT window, to MM and run it for testing, but I can't go the other way - copy from MM to PC. I select the file I want on the MM in the CHAT window(using left pane), click the transfer button(still on left pane), I am asked for a name and location on the PC - I select TEST1.BAS, and click the SAVE button - then things hang. MM waits forever with XMODEM SEND "TEST1.BAS", and CHAT window just sits there forever saying the same thing - there is no activity, no transfer, and I have to close the window and CTRL-C stop the MM. Any idea why that should be? I expect that most people want to transfer files TO the MM, rather then the other way as much, but if it is supposed to work, why ain't it? Smoke makes things work. When the smoke gets out, it stops! |

A strange bug. I don't know why it was failing but I have done rough bugfix. A new version of MMedit is available to download from my website. The main page still refers to V3.4.4 but the download is 3.4.5 http://www.c-com.com.au/MMedit.htm I will update the main page after dinner. Jim VK7JH MMedit  MMBasic Help |

So, can I ASSUME that you were able to re-create the same issue at your end??? Smoke makes things work. When the smoke gets out, it stops! |

Yes, The problem was there for both MicroMite and Maximite. It was all working happily a few weeks ago but I think I introduced a bug with the 'One click" button. Thats the last change I made. I will have to look further but for now it should be OK. VK7JH MMedit  MMBasic Help |

Good morning. I have the same problem when I use the command Connect to Maximite or Chat to Maximite (Micromite) Error: 0 MessageNotUnderstood. I have two micromite (28 pin) assemblies and communication with TeraTerm is correct. MMEdit V 3.4.6 thank you very much David PM |

The only way I can get that message (on either 3.4.5 or 3.4.6) is to pull the USB lead out. Can you explain step by step what leads to the message appearing then I will try to recreate it here!  For everything Micromite visit micromite.org Direct Email: whitewizzard@micromite.o |

What version of Windows and what Chipset does your USB-serial adapter use. Also, what baudrate are your using. The default is 38400. That error message is coming from the language I used to program MM Edit and it can be very difficult to track down. It usually happens when MMEdit tries to write to a port that is not configured or not present any longer. Jim VK7JH MMedit  MMBasic Help |

Good morning . Thank you very much for your cooperation. After the last post I'm back to review the different options that I have in my hands. Right now I have two mounted on connecting plate Micromite to evaluate in parallel with two different programs and join them later for I2C bus. RS232 to Micromite I use a MAX 233 ... ( MAX232 ). First converter ... USB port converter to two RS232 ports "" Sunix ComUSB "" I've opened and has a converter chip MCS7720CQ -GR The PC Device Manager detects "USB -to -Serial Port Driver ( COM4 )" and " USB -to -Serial Port Driver ( COM6 ) " . The specifications of this chip ... USB -1.1 Dual USB Ports Serials ( This version ( 1.1) could be the source of the problem ) The good . Using this module I can open two screens with TeraTerm and both work at the same time correctly. The bad . Using MMedit not work, "Error: 0 MessageNotUnderstood " Conditions with TeraTerm . Micromite Nº One ... TeraTerm 38400 com4 : OK Micromite Nº Two ... TeraTerm 38400 com6 : OK Second converter ... Digitus Brand ... I've opened and has a FT232RL FTDI chip and another chip which I guess is the USB to RS232 converter ( SIPEX ) The PC Device Manager "USB Serial Port ( COM10 ) " detected. MMedit works " correctly " . OK ... Third converter... Brand ... EQUIP. The PC Device Manager detects " PROLIFIC USB -to -Serial Comm Port ( COM30 ) . MMedit works " correctly " . OK ... Ahhh ... if I disconnect second and/or third converter directly get this message . "Error: 0 MessageNotUnderstood ". Issue resolved . Thank you very much . David PM PD : Sorry for my English . |

Thank you for the report. I don't have any converters with the MCS7720CQ chipset to test. I will add it to the list of ones that have caused problems (it's the first one on the list!) I am using the standard Windows routines for accessing the serial port so there shouldn't be any problems but I am not surprised. Jim VK7JH MMedit  MMBasic Help |
