Narrative:

I filed IFR from ZZZ to ZZZ1. Weather was VMC. Clear sky with unlimited visibility and a light direct crosswind of 6 knots. My plan was to depart ZZZ VFR and pick up my IFR clearance once airborne with approach control. I chose runway xx for departure for direction of flight. I self-announced my taxi plan (on what I thought was CTAF) and taxied to the hold line of runway xx where I performed my run-up and before takeoff checks. I hadn't heard any other traffic on frequency from the time I had cranked up.I self-announced I was taking runway xx for takeoff and a straight out departure; and proceeded to take the runway and push the power up for takeoff. This is when I noticed another cessna on short final for the opposite runway xy. I immediately aborted my takeoff and made a sharp left turn; promptly exiting the runway at the same taxiway I had entered from. The other cessna continued his landing uneventfully and taxied to park. I analyzed the situation once clear of the runway and found that I was a digit off when setting the CTAF frequency. I actually had set the unicom frequency instead of CTAF. I corrected the error and got a radio check; then proceeded without further issue.
