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.

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

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.

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

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.

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

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.

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).
Doug.

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'

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, 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.
