I was told of this list, so thought I might start asking some questions. First one is....on the capture/compare module. What is this used for and why would I want to use it? I have an application where I am watching interupts on PortB, and looking for a certain range, ie... frequency of the input to be within a certain hi and low range. Is this a good application for it? Maybe a CCP faq if one is available? -Ash _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com/intl.asp -- http://www.piclist.com hint: The PICList is archived three different ways.
