| Worth upgrading to PCW v3.224? |
 Posted: Tue May 24, 2005 9:45 am |

I currently have PCW/PCB/PCM v3.045. I have been mostly satisfied, but I have noticed some bugs here. I also find that I'm not able to use certain PICS such as the 16F87/88 due to my old version.
My question: is it worth upgrading to the latest version? Are there a lot of bug fixes, etc?
Is there no price discount for returning customers? |

Well, the one year maintenance for PCW is $200, while it costs $350
initially. So that could be considered a discount for returning customers.

I'm not sure I follow you. I've purchased a version back in 2001, but now I cannot just buy a year of maintenance for $200 correct? |

Since you already have version 3.xxx of PCW, it's my guess that CCS
will sell you the one year maintenance for $200.
The "maintenance" is the full compiler. You can download any updates
that they post, for one year's time. You can also download vs. 3.191
(which you should do -- and save it).

Thanks. Why do I need v3.191? |

You should save every version that you download.
Sometimes, CCS will post a version that's buggy. Suppose by the
time that you get your one year's maintenance contract, CCS has
posted vs. 3.225. Suppose it's very buggy. You can't get vs. 3.224
anymore. You want to proceed with your project, so you download
vs. 3.191, which is deemed to be a fully tested version by CCS.
As a minimum reason, you should at least download it as a "reference
version". |

Ah thanks for the info. The version that I currently have, v3.045 is not even listed on their site that shows all the changes...I wonder why.
As I stated in my original post, the main reasons for upgrade are to fix bugs I encountered when using two diferent #use rs232 statements in the same code, being able to use the PIC16F87/88 and other minor bugs I've encountered. Which version if your opinion is the most stable/bug free? |

I haven't done a large PIC project recently, so other people may be
able to answer that question better. Vs. 3.224 seems OK.
