Plenty of stuff you could do with the slave that would previously need a 2nd chip.




Agreed but only to some extent...

Exactly.

Hi all,
now the can of worms has been opened!
https://www.eeweb.com/pro...ital-signal-controller

Besides 2 cores it has also duplicated peripherals, a set for each core, so in fact is 2 PICs in the same package, not simply a dual core PIC.

Yeah, I looked at their code.  If you look at how it works you will notice that the slave code is larger than normal code found in the program memory space.  They do the code building a lot like an Intel hex file, where each "line" of code starts with a record entry that dictates the length of the line and where in the PRAM the code is suppose to go.

Why does this, somewhat, makes me think of the PKOB LVP programming? I wonder...
 

Best regards

Hi
 
Surptise  Surprise!!!
I failed to re-engenieer the link in one of the quotes of my previous post, and .....  the forum didn't complain!?!?!?
Might it be that this dam*** forum has been improved?

It even works.
But I wouldn't bet on improvements - might have been some temporary "mood".

Hi
 
Even editing a post (typos) after it has been replied to is working!

FaulknerPD MC has published AN2721 (Getting Started with Dual Core).
 

 
Anyone got a link to this? The link on the product page goes nowhere, and attempting to search the APs also shows nothing.

Its OK, found it using Google ...
 
Typical Microchip failure again ...
 
Just hope this isn't indicative of problems with the chip ...

I don't think it is a coincidence that the first dual core is a motor part. One core motor control using tight loops, other communication + other (lower speed) I/O.
 
That's also the application that we have in mind.

That is what I am looking at too. I could also see applications where having a second processor to deal with a complex interface protocol would be worth while so it is off loaded from the master processor.

There are still some missing docs.
1. programmers ref. manual (DS70000157)
2. the new dma.

MPLab X playing up, bug in your code? Nevermind, Star Trek:Discovery will be with us soon.

I'm also missing the usual short paragraph on interrupt latency. And that while the datasheet lists:
 
Five Sets of Interrupt Context Selected Registers
and Accumulators per Core for Fast Interrupt
Response
 
Which sounded to me something like shadow registersets to depress interrupt latency. (like SRS on pic32mk)

PHY bit bang on one... network layer on the other. I needed one of these in 1997.

PHY bit bang? Which bit rate?

I hope he doesn't get bucked! ;)

This forum is mis-configured so it only works correctly if you access it via https protocol.
The Microchip website links to it using http protocol. Will they ever catch on?
