Do I Need Debugging Headers for 18F Chips?

Status

Hi,

Until now I've been using a 16F690 chip in my projects because that was the chip that came with my Pickit2. I would like to try using one of the newer 18F series chips but don't want (can't afford) to buy a debugging header thingy like the one I use with my 16F690 as shown below.

Is it the case that some of the 18F chips have the debugging facilities 'built-in' thus negating the requirement for a seperate header? I've read some of the data sheets but it's still not clear to me if this is the case.

Thanks in advance for any help.

You will find the 18Fs a lot easier to program with little to bother about with Page and Bank commands.

If you are just experimenting, then get a 40 pin chip - only a few pence dearer - the 18LF4620 is a low price and will also run at 3v3 is you neeed it in the future.

Using a 40 pin will allow you to easily dedicate Mclre, PGC and PGC to the PK2 so no switching over or disconnecting each time you go from Program to Debug to Run.
