Thanks for responding.
Still somewhat puzzeled..
I suspect this is the case because of the high gain nature of these
devices. I have previously breadboarded other PIC projects around this
noisey environment and the only experience with noise is the usual cause,
insufficient supply bypassing/ no pullups etc. -which is not the case here.
I can open the path between the IR receiver and the pic input and
the only place I see the noise appear is on the unterminated receiver
output, the pic is unaffected as long as GPIO termination is present.
I am sure another contributing factor is using an uncoded IR carrier,
which I hope to fix shortly and should improve noise discrimination
Thanks again -Ken.
