Actually that should read N1200 not T1200.

It's a mimic of the circuit I saw on Rentron with a 38khz pwm and serout/serin.

I'm driving a 2n4403 to switch the anode of the xmtr led.....the data looks perect on the rcvr serin terminal. I'm simply using portb to look at the data....

START:

SERIN PORTA.0,N1200, [QUALA,QUALB,DAT]

PORTB.0 = DAT.0
PORTB.1 = DAT.1

AND SO ON

GOTO START


Using a 16f628a--comparators are off.

I see perfect data at serin but nothing on the portb outputs....took the data directly from the sharp module and also through a 4401 buffer.

Oh well.
