hi,
In Oshonsoft sim, when C,4 is set high, B,1 goes low..........when C,4 is set low, B,1 goes high.

Looks OK.?
See images.

yes pic and proggie works ok, but ultrasonic still wont respond, port wont go high when ultrasonic is plugged in, nor do i get feedback pulses, , maybe i should contact manuf?

my concern for the pic/code was that with my code style it will work to send ping and detect response on pin c.4 right, Im using correct type of pin right?
