Hi Ttelmah,

Thanks for that. You've hit the nail squarely on the head, as it was indeed MPLAB, or maybe more precisely the ICD3 degugger that I'm using, that seems to have been the cause for WDT se ...

Okay, after some searching of the forum, I think the question might be better put:

MPLAB seemed to be indicating that my WDT configuration bits, as set in software (listed fuses), were such that bo ...

I seem to be having inordinate difficulty making the WDT work on a 24FV32KA304, and was wondering if anyone might be able to assist?

I enable the WDT early in main() with setup_wdt(WDT_ON);

My ...

There's no address error at 0xAB2, the faulty instruction is one assembly line above, not shown in the post.

Hi FvM. Nice to have your expertise along for the ride.

Well, if the PCD V4.081 addre ...

Hi Eoin87,

Did you ever manage to find the cause of your address error reset, because I have exactly the same thing happening.

No effect of increasing the stack size suggest ...

First point is to identify the kind of error trap causing the reset.

I guess you get an unhandled trap reset, by implementing an address error and stack overflow trap handler you are able to distin ...

Er. I think you will find 256, is the default size. It is _not enough_, if you use any of the complex printf formats, more than perhaps one or two ISR's, some of the maths functions, etc. etc..
Take ...

Have you increased the stack size from the default?.

Hi Ttelmah,

Thanks for the valuable input.

Yes, I think that I've addressed the stack size possibility. I tried adding '#b ...

Hi,

I'm using the CCS Modbus demonstration code on a dsPIC33FJ128, though without the CCS UART driver, and with my own UART set-up routine.

Periodically, the controller will undergo trap resets, ...

Hi Jeremiah,

Thanks for the prompt reply.

Take a look at #INT_RDA and #INT_TBE in the manual. They are used for UART1.

Nope, I don't want to use the CCS interrupt declaration methods. They'r ...

Hi,

Writing my own UART code, but need help with CCS compiler interrupt service routines...

On a PIC24F I have enabled both UART TX and RX interrupts, and selected TX interrupt to fire on transm ...
