As the title says. I'm looking for volunteers to test a new release of the MMX firmware. A new release would have lots of the Pico functionality, escape sequences, regular expressions, jpg decoding, Performance improvements, + new displays e.g. the 800x480 IPS displays like the ARMMITEF407. I would also try and incorporate as much of the advanced CMM2 functionality as possible. In terms of performance, the MMX beats everything except the ArmmiteH7/CMM2 including a Pico clocked at 378MHz and has lots of memory (>300K variable memory/program size) Let me know if interested For reference compatible PIC32MZ are in stock at Farnell UK at prices from about GBP11.80 and I have previously posted a number of PCB designs for these chips, 64-pin, 100-pin and 144-pin Edited 2023-08-24 20:36 by matherp |

I do have a MMX in the cupboard so I could do some testing for you. I don't have much of a range of displays etc but plenty of other peripheral modules. Jim VK7JH MMedit MMBasic Help |

I have a couple, the standard "red" board and the lovely "Navigation" issue. both are in (almost) daily use here, the red one is in my workshop assistant GP machine... I don't have specific needs as everything is covered but who knows what will happen when the opportunity is there  Don't go to any trouble unless you get more support. cheers h |

I have one. If you are implementing the usual suspects, CMDLINE$ ,EXECUTE, CALL sub and CALL function I can run some of the automated tests I have been using. These use a modified versions of Tom's unit test frame work from the SDCard. Gerry Edited 2023-08-24 22:59 by disco4now Latest F4 Latest H7 |

WOW, YES please! As you say, this is chip is the best; absolutely my favourite. |

just occurred to me, would the update include Gerry Allardice (disco4now)'s recent work? I use LIBRARY a lot |

Not sure what you mean. MMX already has library command |

| CaptainBoing Guru Joined: 07/09/2016 Location: United KingdomPosts: 2076 |
with all the updates that occurred recently, I thought the LIBRARY command had gone west(?) and Gerry had recently restored it in his F4 version of the FW. Maybe I am getting confused... easy done |

MM Extreme is the business! Hook up an SSD1963 screen and wire in a USB socket, put in a dongle for a wireless keyboard ...and simply what other MicroMite is so stunning? It works with a mouse ...and even a camera. 144 pins for comprehensive expansion. It really is simply the best! Come on, folks, dig out the MM Extremes - or build a new one now that the chips are available once again. |

Waiting so long for an MMX update. Yes please ! Thanks peter  PS: Maybe with a free SPI-port choice for the display , like with the SD card. That would be great.  Edited 2023-08-25 07:08 by athlon1900 |

Yes please Peter, I have a 144 pin 'red' board with 7" SSD1963 and a 'black' 100 pin navigator board with 4.5" SSD1963 I can assist with. Also, if you would like assistance with the manual, I would be happy to take that on (like the MMB4W manual).

Thanks for the support. I'll put some work in and post a beta on a new thread. panky: your offer on the manual is greatly appreciated. Send me a PM with your email address and I'll send you the current version. You may want to get the Armmite source off Gerry for some large-scale cut-and-paste |

dangerous territory, but if you are open to wish-lists for basic language enhancements; an SPI READ X$,len would be a nice touch. Good counterpoint to the WRITE jus' sayin' Edited 2023-08-25 18:07 by CaptainBoing |

Well this afternoon at work I finally got to have a chat with the IT guy who has been trying for 12 months to get this custom machine working. Ok it's a hopper based appliance that takes photo's of single parts as it they travel thru the setup, so 3 camera's and a blower system for ejecting the defect parts. I said to the guy how is all setup and are what embedded board are you using where I got a blank face  When I got a look at the screen and saw it had windows on it my comment of it's taken you 12 months to get nowhere that is your problem where a micromite would be a perfect job. Now would the MMX output to a VGA/TFT monitor so a big screen can be used. For an embedded solution to make a machine work and the youth of today thinking windows can solve everything a huge reset is due and I did him to take a look at this forum and just learn  Cheers Bryan |

I resurrected my 144 board, I can't remember how far I got with it. I can't get the RTC to work. Using Option RTC 15,16 I get RTC not responding. Is the fact that the module has 4.7k pullups and the board also has 10k pullups a problem. I've tried 3 RTC modules and checked the battery. Edit... I removed the pullups from the RTC module and still have the problem.

@palcal Have a look at this link Extreme Update - there are a number of explanatory notes including a reference to the rtc. panky ... almost all of the Maximites, the MicromMites, the MM Extremes, the ArmMites, the PicoMite and loving it! |

@ Panky, I think WW put pins each end for support they just duplicate the connections. I have checked the SDA and SCL connections back to the chip and all OK. I will try putting the RTC on I2C 2 and see if that works. Edit.....All good, my bad, pin 16 was not making contact, resoldered. A bit hard at my age soldering a 144 pin chip.
