I'm new to pics. Whilst I understand the principles of the code, I'm having difficulty getting the head around the config settings in the header. I'm working from 2 books and with a Velleman Kit programmer. I know I have to declare the settings in the header but I'm confused by what appears to be conflicting information from the sources I've explored. One of the books simply gives a "standard" header and uses it over and again whilst the other glibly states that "H'3FF0' sets up LP OSC, WDT OFF, PUT ON, CP OFF. I know that '3FF0' equals 11111111110000 in binary and I think I know that these set the various bits. However, suppose I don't want LP OSC, WDT OFF. Which bits do what??? The values for int R/C Osc, Int Pullups ON/Off, etc continue to elude me. Can anyone suggest an "Idiot's guide" to explain in low-level terms how to set the configs? -- View this message in context: http://old.nabble.com/pic-config-settings-explanation-wanted-tp28336501p28336501.html Sent from the PIC - [PIC] mailing list archive at Nabble.com. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
