Dummy post to hopefully stop topic flashing.

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?

Well, I'll put this in here in the absence of thinking of anywhere else to put it.
 
Investigating how to connect up an LCD display I discovered there is no PMP or EPMP, so one will have to bit bang the R/W, Dir, CS and Enable lines. Well, I guess the latter three would be bit banged anyway, but it would have been nice to have the R/W strobe automagically.
 
I guess the lack of a PMP or EPMP is due to the need to be able to switch between master and slave. Also I guess something had to give to get the real estate for the second core ...

From the MPLABX 5.05 release notes:
dsPIC33CH128RA508 and companions. Any intel?

And what about the dsPIC33EDV64MC205 that is also mentioned with a heap of yellow indicators under programmer support? This one may have been available for a while, and I haven't been keeping my ear to the ground ...
 
Or the PIC32MZ1025W104132_DEV and non_DEV version ...
 
Interestingly the 33CH128RA family don't appear in the device architecture family list. They also do not appear in the Debug Tool HW Features list.
The 33Cx families don't have any resources required listed in the Resources Reserved by Debug Tool ...

Doubt it, can't find a datasheet anywhere.. altough it will probably be a part on its own, having an integrated FET driver and all..
 
Hoping that we'll have 33CH128RA include files in the next release of XC16..

FYI explorer 32/16 demo was updated.
 
For MP508 it only seems to upgrade mplabx project files to a newer version, and comment the maxtemp define in system.c that needed to be commented out earlier.

Because i'ts even more confusing to keep track of which pin can do what, i made myself a colour coded cheat sheet for the 80pin variant

Nice one. i have to admit it has taken a bit of head scratching to attempt to get ones head around what functions come out where for which processor.

Yeah, should have done it sooner. I spent way too much time on a layout before realizing i finished up all programmable pins because some functions like analog or I2C could have been moved to other pins.
a color coded view is easier to me to look at instead of the two pages table
 
also, you realize how useless PORTE actually is, i'll either scale back to the 64 pin or keep the 80pin but with a lot more of blinky outputs for diagnostic
 
EDIT: And the planning is complete!
Wow, making the diagram + redoing the planning took me less time than doing the planning without the diagram.
Again, i'm amazed at this chip: By the fact that EVERY remappable pin is input/output (aka all RPx, no RPIx) i ended up using ALL of them, except for some PORTD and PORTE that were GPIO only... i can handle double the signals i could with the '33EV, even if i use the 64pin instead of the 80pin.
And i kept aside the SPI port and the DACOUT pin for future use
 
If i decide to give up dual debugging i can free up some more analog and digitals.

The chip is missing some modules, true random number generator and usb.
 
128KB is not enough space so looking forward to the 512KB version.
 
I think it would be possible to program the slave from an external device such as eeprom or sd card but using the LDSLV instruction only reads from program space.  It may be possible using table writes, the slave section has a 6 byte header:  Destination address (2bytes), page and flag (2bytes) , size (2bytes).  The slave consists of many of these 512 byte blocks.

More RAM as well! Or the option to add external RAM.

Glad to see Pickit 4 (beta) and ICD 4 support (beta) now added for these parts in MPLAB X 5.10!

 About time but these should have been green from day 1.

Has anyone had any luck debugging the slave with either SNAP or ICD4 under mplabX IDE 5.10?
 
ICD3 works for me and finds the slave with revision 0x4002
SNAP revision 0xffff
ICD4 revision 0x0000
 
both the SNAP and ICD4 start the erase sequence and just stop
 
This is using the dspic33CH curiousity board.  I've had the snap working with the ATSAMV70 so I am pretty sure it is ok and the ICD4 is fine as far as I can tell.

The status of this chip is in YELLOW on the pickit 4 as of v5.10, the Pickit3 was GREEN.
 
Check the device report for your programmer.
