Post by thread:[PIC]: A little therapy....

May I please have permission to get something off my mind, by way of therapy? Thanks. Here it is: I HATE! to read code that makes provision for every model of PIC ever created since the memory of man runneth not to the contrary! It makes the mind weary and the body tired. Thanks. That is a vast relief. :-) Back to studying..... John -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you. See http://www.piclist.com/#topics

You may come to appreciate this once you've done a few projects and realize you want to reuse code between them. What/where have you seen specifically that you are objecting to? I do lot's of projects on lots of different PICs, and try to minimize customization required for "standard" modules. Just today I ran into an incompatibility between a 18F1320 and a 18F252. The code was running fine on the 1320, but was not getting any A/D readings on the 252. This was because only CCP2 starts an A/D conversion on a special event trigger on the 252, but this is done with CCP1 on the 1320 because it only has one CCP module. I left the old code in there and added IFDEF CCP2CON to automatically assemble the appropriate initialization code in case it ever gets moved back to a 1320. I had to do a similar IFDEF ADCON2 to distinguish between the traditional and advanced A/D. The two have quite different control bits. You never know when in the future you might want to cut and paste code from an old project. ***************************************************************** Embed Inc, embedded system specialists in Littleton Massachusetts (978) 742-9014, http://www.embedinc.com -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.

If someone is gracious enough to make their code available to look at, and learn from, I would undergo torture before revealing names! (Well...some torture, anyway...some mild torture...maybe having to listen to old Beatles songs.)

I can write a little pre-processor for the source code to filter out the useless stuff......Good on ya' Olin! (Perl, here I come).

I was wondering if it was any of the code on my web site. ***************************************************************** Embed Inc, embedded system specialists in Littleton Massachusetts (978) 742-9014, http://www.embedinc.com -- http://www.piclist.com hint: The PICList is archived three different ways.

I'm talking about really convoluted code, which uses a lot of "else" statements to check the existence or non-existence of hex numbers. IFDEF statements (or the generic equivalent) are easier to deal with. -- http://www.piclist.com hint: The PICList is archived three different ways. See http://www.piclist.com/#archives for details.
