using PIC 16f84 at 315 MHZ

[abood]

I know my question is stupid but what to do to make this thing work.......

Actually, you didn't help me with your site

please directly answer my question as I explainded previously.... with sending me throw these sites

OoooKaaaay,

It really doesn't matter what frequency the RF link is operating at. The 16F84 will have it's own oscillator running at 10mhz or less. Simply add a DEFINE OSC 10 for a 10 mhz crystal, or change the number to the appropriate value to match you're crystal. And, be sure to set the oscillator config to "HS". (You will never get a 16F84 to run at 315Mhz)

Then, a quick look in the manual shows that 188 is the Mode for 4800 baud, or 16572 for inverted 4800 baud.

Or, go here for a complete list of Serin/Out modes.
