Hello,
 
I am fairly new to the pic family of controllers and have a question.  Can i program the 16f84-04p in-circuit?  It is very important in my current app (micro-sized robot) to be able to program and debug while the chip is in.  I hear lots of talk about removing the chip and inserting in a programmer. I cannot do that every time i need to tweek some code. Am i way off?  Do i need a differant chip?  Thank you for any help.
