Hi all,
my IR just doesnt budge....
I poke(0x1000, 0x40) at the C: prompt and connected the oscilloscope
to the IR LED.
The oscilloscpe showed a straight line at about 5Volts. I tried using
Radio Shack IR sensor card and but didnt find any trace of IR beams.
The LED 9, glows all the time, but i cant see any IR o/p nor the
square wave in the oscilloscope.
Since the LED 9 lights up does this indicate that U7 and U9 are
working fine?
Suggestions, help, comments please.
Sriram
