hello to all,
I have ordered on ebay a board with a PIC32MZ
http://www.ebay.fr/itm/181805050475?ul_noapp=true

and I have received this mail from Eleckropic (Mounir) :

Hi Pierre
Thank you for ordering the SnadPIC MZ board. I know you have ordered a SnadPIC (470) before and you have left a nice Feedback in my website. Many thanks for all.
I have a quick look at Micromite Extreme Edition, and i realized that the SPI2 should be used for the SD card. Unfortunately the SnadPIC MZ use SPI4 for that.
Is this a problem?
For the 12MHZ external oscillator : I am in short for now for this type because I used to use the 24Mhz oscillator. I had only one and someone else had ordered the board with that crystal. There is no problem in the near future because i will order other few 12Mhz crystal, may be on Monday or Tuesday i will have it.
So as you can see there are two problems, and the most important is that of the SPI. What do you think now? Please let me know if you have any other idea. Best regards. Mounir

what do you think about the 2 problems ?
SD card on SPI4 and not on SPI2 ?
24 MHz crystal in place of 12 MHz ?

I can change the crystal for a 12 MHz, no problem to desolder/resolder...
but what about the SD card ?

thank you for your help

Pierre, from Nimes, south of France

I can easily produce a hex for the 24MHz oscillator
I'm intending to just use an external SD slot and ignore the on-board one

Thanks matherp well done on the new port.
Hope that MMbasic can now move forward and expand to include more advanced features and functionality.

There are number of pre-existing PIC32mz boards out.

What are your plans for the MMbasic firmware support for different versions of PIC32MZ?

ok Peter,
I am interested by the "version" for 24 MHz oscillator
but I can wait...
perhaps I replace the crystal 24 MHz by a 12 MHz when I receive the board

thank you Peter

Pierre.

The EC versions don't have hardware floating point so there is no reason to support them and they couldn't share the same hex fileEdited by matherp 2016-11-18

Don't do that. I've also ordered the 24MHz version so will definitely make the code optionally able to be compiled for both

Peter,

Have you had a chance to consider the questions below?

Many thanks,
Doug.

panky said Great work Peter,

Does your implimentation use a bootloader like the Maximite or is a PicKit 3 needed to load EMMBasic?

Thanks for your great work and contributions,
Doug.

PS. Peter, do you have any plans to modify/update your backpack board you designed? That is a terrific little board especially for testing or just playing as it has connectors and support for all the TFTs from 2.4" to 8"

Doug.

... almost all of the Maximites, the MicromMites, the MM Extremes, the ArmMites, the PicoMite and loving it!

PicKit3 or Picprog32 (subject to testing)

Yes in the next few days

Can anyone help me please.

I am using MPLAB IPE v2.15 and am preparing to load the latest MatherP firmware for the MM Extreme.

However, only the PIC32MZ2048EC devices are listed and not the EF PIC32s.

So how do I add the EF range to my drop down list in MPLAB IPE?

Update to MPLab IPE v3.45 which is what I'm using

Thanks Peter, that worked (once I eventually found the download link on their website!)

All of this to run "dressed up" old quirky Basic language in 2016?

If you really need interactive scripting language on the powerful microcontroller why not use much easier and exponentially more powerful up to date language like Python, or anything else (C , javascript, etc.)

Can you provide examples of this "exponential" power? I Googled "BASIC vs Python" and there is no shortage of those who state that Python is "better" but no examples of why! I guess that it's just sounds cooler at the pub, to say that you're a Python programmer

JohnL said
on SOC boards with proper multitasking operating system

Define "proper". If it's not hard-real-time then it's of little use to my industrial control system needs.

Right now, I am using an $8 micro-controller that runs at 80MHz and is programmed using 100% BASIC, albeit compiled.

1) I am reading FOUR incremental quadrature encoders with all quad-decode performed in software at the rate of up to 2MHz (2 million quadrature counts/sec). Most industrial rotary encoders are only good for 500KHz but 1.6MHz models are available.

2) I am running FOUR PID servo-loops with an update of 125uS each, the output of which is 12bits of PWM servo-motor command @ ~20KHz using BASIC and the chip's timers.

3) Serial communications running at 460K-Baud, 100% BASIC code, no UART. This can be faster but is already overkill for my needs.

Once again, a single 80MHz uController, no special hardware, for eight bucks!

Not a single interrupt required.

Can you show me ANYTHING that can achieve this performance using the "exponentially more powerful" Python?

Thanks to BASIC, I have been self-employed for 30 years and have baffled many people with such rapid application development.

I LOVE the MicroMite and plan to utilize it as a host to my real-time control devices.

I don't use dedicated HMI's as I prefer to use heavily protected Android tablets, linked via BT. For my HMI code, I use B4A (BASIC For Android):

No, but I did recently read a 9 page magazine article showing how easy it is to connect a DS1307 RTC to a RPi and make the time available to Python!

And the code was easily explained over three of these pages!

Explaining RTC GETTIME, RTC SETTIME, and a photo of a plugin RTC module won't make much of a magazine article in comparison to the powerful RPI/Python I guess

Magazine articles are a pretty mixed bunch, some really quite poor as maybe that one was or very step-by-step for true beginners.

To be fair RTC GETTIME etc don't teach anything (and aren't intended to), whereas maybe the article tried to?

You could probably make the RTC time available in one line of python but it wouldn't make an article at all and wouldn't teach anything...

Wouldn't hep fill a magazine - the editor's biggest wish - either.

From the last pinout on the 'other ' thread, Pin 17 is A/D/COM3-RX, and 21= A/D
