This is not simply a case of a bug that did not get fixed. It is also a case of code which did not fulfill the specification doc (the app note). Bugs I could accept, after who has not left more than one in 'finished code'. (though the apparent bug in this case means that the system could not operate as specified) The fact that this is published by the manufacturers of the devices makes it, to me at least, even more annoying & leaves me skeptical of any other app notes. As someone else said they are great sources of ideas, but having seen this particular app note, I wonder how many of these ideas will work without significant rework..... Anyhow when I get a couple of more things sorted with this one, I'll put it up for others to use.

Subject: Re: [PIC] Microchip app notes quality. (Long grumble) A problem with writing code then moving on is that bugs never get fixed. In a production environment, we update code as production test and customers find problems. I think an ap note tends to be written, published, then never looked at again. The code pages at http://www.piclist.org are great since users can add comments. It might be kinda interesting to have a pic code wiki or CVS where users can contribute code, other users can comment on it, remove bugs, make improvements, etc. Harold -- FCC Rules Updated Daily at http://www.hallikainen.com -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
