Hi, Ajish.

 

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

through software. 

 

 

Thanks again -Ken.
