Basic interfacing of tsop ir receiver with Atmega16

[Shankar]

Hello,

I have a Atmega16 and a Tsop ir reciever. All I want to do is, glow a led, when the receiver gets a signal, from any standard tv remote.

Here’s the code outline, i have tried

 

ddrb=0x00// part b as input, where i have connected tsop receiver to pb0

portb=0xff// pulling up part b

ddrd=0xff// part d as output, where i have a led in pd0

 

while(1)

{

   if(pinb)// i get some value at the reciever

   portd|=0b00000001<<pd0;

 

   else

   portd=0b00000000;

}

 

Sorry for mixing up hex and binary forms…I am a newbie trying out things. Kindly guide me through this problem!

 

Thanks in advance

So tell us about the output that you are getting.

the TSOP sensor output is normally high and it goes low when it detects signal. also check for signal change on any single pin only not whole port.
