Raymond,

I haven't done it for Pioneer brand I/R remotes, but I have for the Sony
spec.  What you're missing (and what's probably most important) is the
modulation frequency (generally 32, 38 or 40 KHz - Sony uses 40 KHz).

When I did it for the Sony, I created a 80 KHz Timer Interrupt and
incremented a "Real Time Value" and toggled an I/O bit each time I entered
the Interrupt Handler.  In the mainline of the program, when I was sending a
"1" (modulated at 40 KHz), I simply enabled the TRIS bit for the number of
80KHz "ticks" to send the pulse (the same thing was done for sending no
signal at all).  The I/R Tx LED was wired as a normal diode.

I used the I/R Tx/Rx LED pair from Radio Shack to generate and receive the
signal (receiving to debug it before I sent it to my stereo).

This method really won't be that precise in terms of timing, but my Stereo
likes it just fine!
