Hello, i am new to programming and am using a pic18f25k22 im trying to set it up to use an external 8mHz oscillator but from looking at the datasheet i am confused about how i do this any help would be appreciated thanks connor

IS that an really an oscillator or do you mean a xtal or a resonator, they all have different requirements
more info is needed and what have you tried ?

If you insist on using an external oscillator/resonator/crystal there are some examples of how to hook it up in the datasheet on page 33.

However, most people would be glad to use the internal frequency selectable oscillator. Saves pins, parts and cost.

As above, tell us what you've tried and most will steer you in the right direction.

think ive managed to do it now using the following line

#pragma config FOSC = HSMP

im new to pic programming and struggling to set the pic up from scratch so the i/o pins are outputs ect

i am using an 8mHz xtal i will be using the i/o pins as outputs to mulitiplex a 7 segment display

If i'm not mistaken thats C, so I guess you're on the wrong board.
