external clock / internal clock

[grounded]

I'm trying to go from using the internal clock to using a external clock
on a 16f676 using MCS/PBP /MPASM not sure what all I need to do

thinking I replace _INTRC_OSC_NOCLKOUT with this _XT_OSC
and do I still need to DEFINE OSC 4
thanks

Yep, DEFINE what ever speed the external is running at.

Could be XT or HS.

What are you going to use for the external?

thanks
I'm adding a 4 mhz crystal
I'm trying to do some PIC to PC comm. using DEBUG.
Melanie's Communications Example : PC to PIC bi-directional dialogue
and with the internal I was having the problem she talked about hoping the external will solve it

[mackrackit]

If you are using one with built in capacitors use HS.

thanks again
I used ext caps so I guess that would be XT
