Hello,
The compute of stack size by linker it's not enough for
our application, sometime the device go to reset state.
How to set manually or increase size the deep of stack size to
24ep512xxx controller ?
Thank |

Thank,
in the ... \ PICC had a manual in pdf, outdated, I thought that upgrading the compiler was updated also the pdf but it is not so '
He said to use but did not work, I had to write, as specified in the manual updated, | Code: | | #build(stack=0xDE00:0xDFF0) |
and now it seems to work
also not work if write | Code: | | #build(stack=0xDE00) |

I called CCS Tech Support with a float issue (see elsewhere on the forum), and it was really a stack issue.
They told me to use that syntax.
The Stack sizing will be fixed in next release I was told. |

Thank response,
I think CCS, should enter in the online Help or the PDF manual, ALL syntax provided.
Or, when you download the 'update, which should automatically release also the' last updated manual.
I lost two days for this!
Thanks anyway to the forum community ... |

| Don't worry, I've been using CCS since 1999 and that has always been their major problem: documentation. It's just plain horrible. It has always been that way and from what I have seen over the years, I doubt they'll ever update it. |

There are actually two manuals with CCS.
The .chm manual that comes 'with' the compiler, and the .pdf, which is always a separate download.
The .chm, is easier to use, but is always older than the .pdf.
When you update the compiler, it includes the .chm manual, but does not include the .pdf. You must download this separately.
Then there is also a 'readme.txt' with the compiler, that contains small changes, that have happened since the last pdf manual. Beware though, that since the manual with the compiler, is the older .chm manual, there will be gaps between this and the readme, unless you download the .pdf.....
#stack appeared in the readme, about twenty versions ago, for a couple of releases. It was then removed. The syntax for #build is in the pdf manual, and does work correctly on the current releases. #stack worked for a few more versions, but has now been removed.
What appears happened, was that there was a problem with the #build syntax, and #stack was implemented, and documented only in the readme. They then got #build working, and have got rid of #stack, but now properly documented the #build syntax.
With the current compiler versions
#BUILD (STACK=512)
Correctly allocates a 512 byte stack.
#stack now gives an 'invalid pre-processor directive' error. |

What chip?.
Have just tried 5.046, and it merrily resized the stack OK for me on half a dozen chip. |

You are putting it right after the include file?.
So:
| Code: |
#include <33EP256MU806.h>
#build(stack=0x300)
#device ICSP=1
//etc..
|
Have just tried, and it merrily sets the stack for me on this chip.
But it must be done before anything uses the stack.
Have tried with 5.046, and 5.053. |
