Maxwin: 1. Cool 2. Whoops, i had it there before i SX/B 1.5'd the code, I'll add it back 3. Okay, sigh :D

JonnyMac: That was the first thing that came to mind when i started. I did some research first and found this post
                    http://forums.parallax.com/forums/default.aspx?f=7&m=199012. The issues about accuracy and Bean's
                    great code example (RPM.xsb) pushed me into the route i used. I wanted to use the ISR on the display's POV but i thought
                    an ISR would interfere with the PULSIN commands. Would it not? /rubs_hands_excitingly 

Bean: AH! I went back and re-read the help file....whoops! When i saw the 15% and 85% i thought you could choose TTL or CMOS level as well.
           And thanks for the RPM.sxb! It is much more accurate then what i would have cobbled together! Quick bonus question, right now I'm feeding it
           10HZ pulses from the PIC on the PDB for testing. When i run my SX at the full 50mhz, (versus say 5mhz) my expected rpm of 600 drops to 590. Any ideas?
           I would just keep the speed lower, but someone gave me a whole bunch of SMD SX28s with SMD 50mhz resonators on boards.
