why ccs not already offer compiler also for PIC32? there are plans for it? i think is big mistake for ccs not have it.
thanks |

Because it is a completely different chip.
Not even a 'descendant'. Every feature is different.
It is based on the MIPS core, for which quite good compilers are already available.

Possible interest for a PIC 32 compiler is one point in the new features poll on the V5 download page, so CCS
is apparently thinking about it.
Besides the points mentioned by Ttelmah, I'm under the impression that CCS C has still difficulties unable to cope
with the number of registers to be managed with 16-Bit PICs, because there have been various bugs related
to register confusion, and there are still new ones from time to time. So I wonder if it would be a good idea
to start a PIC32 compiler development.
Another point is that PIC32 applications will often require TCP/IP support. The Microchip TCP library
is quite good, and well integrated with C32 (and probably XC32) compiler. In a realistic view it takes
several man years to to go there. |

I agree with the later part regarding development effort however I would have classified Microchip's IP stack as rudimentary.

Definitely - it's a bare bones "get the chip just running"...
gotta give 'em credit though...

Hi Andrew,

It works for me as a usable starting point for internet enabled products, although some parts need to be
complemented. E.g. for the FTP part, rudimentary hits the point.
The other question is, what would you suggest as a better (ready-to-use, more functional, less buggy, possibly
smaller footprint...) TCP stack alternative for PIC32?
I apologize for moving from the original topic. To close the circle, if CCS decides for making a PIC32
compiler, it will most likely use a recent MHCP application library version for TCPIP.
Regards,
