Thanks Ttelmah, I'll report it to CCS.

I was trying to find a proper reference in the C spec but couldn't find one. As far as I could see enums in standard C will never be smaller than a char anywa ...

Compiler verson: 5.118
Device: DSPIC33EP512MC806

Consider the following example code:

#include <33EP512MC806.h>

// #device CCS2

#case

#use delay( crystal=12Mhz, clock=120Mh ...

I have an old project using the can-pic24 driver which I notice is deprecated.
I do not see a reason either in this driver or the suggested newer driver.

Does anyone know why the can-pic24 driver ...

Okay, that makes sense.

I have removed the interrupts from my bootloader, using polling-based methods instead as you've suggested elsewhere.
So I can just rely on the jump_to_isr() routine to hand ...

A follow-up question about this statement:

On PCD, things are very different, since the hardware automatically
calls the individual routines for the individual interrupts.
(How) does this change ...

Thanks all.
I still wasn't 100% clear, so here are some concrete examples.
They mostly back up Ttelmah's points (though with one surprise).

All examples using a dsPIC33EP512MC806 with compiler V5 ...

The following line from the #int_default description in the CCS manual is not clear to me:

Description:
The following function will be called if the device triggers an interrupt and none of the ...

Thanks, that works.

typedef struct menu {
uint8_t id;
char const *text;
//struct menu const *children[MAX_CHILDREN];
int32_t const *children[MAX_CHILDREN] ...

I am trying to store some menus in a tree:

#device CONST=ROM

typedef struct menu {
uint8_t id;
char const *text;
struct menu *children[MAX_CHILDREN];
} menu_t ...

If I remember correctly, you will find that it doesn't handle sending the
'first' character without the interrupt being explicitly triggered. What
happens instead is after a few characters are loa ...

That unfortunately, has the error, that it should only ever be used with
binary buffer sizes. Otherwise if you use a byte sized division anywhere
else in the code, you will get a warning that inte ...

I'm trying to set up buffered serial TX on a dsPIC33EP512MC806.

I initially used ex_STISR.c but found that the TBE interrupt only fires once.
I found
#include <33EP512MC806.h>

#use dela ...

My original problem is not specific to timer2, I see the same result if I use timer3/4/5.
In my actual project I use multiple timers and only noticed this behaviour on one of them (timer5 iirc).
Tha ...

Searching for the CCS functions is exactly what I had done, so that makes sense.
Does the bTimer2Enabled flag refer to timer2 as in setup_timer2() (and so should I avoid using timer2 myself?), or is ...

I can certainly understand the tick dependant timings of the stack itself not working, but why does my timer2 also not work (not used by the TCP stack)?
