Hi Im Trying To Build An NEC Decoder.
I Connected A TSOP1738 To Interrupt 0 Pin (P3.2) Of 8051.
To Make The Port as An Input I Made it High
TSOP1738 Too Is In High Normally And Goes Low When It Receives IR Pulse.
Any How The P3.2 Remains Always High.
How Can I Detect Incoming Of Pulse.
Bit Confusing To Me Can Anybody Help.
(Hope Am Clear About Software Logic But The Hardware Part Confuses)
