Never used pulsin. So if I knew the pulse width of the 38khz signal, I can compare it to a result pulsin gives? I just read something where it says it measures just one pulse, either low or high state and then goes to next instruction? Why a word variable if it just measures once?

I get frustrated with some of the PBP commands. The manual is too vague. Wish for every command they could have done another page just with code examples and an explanation of what's going on. (just me venting).

I found that Rentron code. Wow. It's all there and well commented -- I'll try it out. His comments really spell it out and teach.

Pulsin works great. Heck, I just used the first part of that rentron code and did this with it --
I get a perfect momentary on/off with a bit of needed pause.


Main:
PULSIN PORTB.0,0,Leader ' leader pulse is ~9mS low-going
IF Leader < 850 THEN
LOW PORTB.2
GOTO Main
ENDIF

IF LEADER > 850 THEN
HIGH PORTB.2
PAUSE 300
ENDIF

LEADER = 0
PAUSE 100

GOTO MAIN

Just a question ......Why:-

GOTO Main
ENDIF

I would assume the other way round .....Genuine question. I can never understand software fully :-)

I think it's a method of skipping other IF/THEN options.

It could also be structured with...

IF This THEN
do something
ELSEIF That THEN
do something else
ELSE None of the above
Don't do anything
ENDIF

Only 1 option will be selected, forcing a break from the test once a match is found.

Got it

Thank you

it's working fine but I added leader = 0 to clear it out (duh)
should have thought of that.
I need to put the breadboard in the sunshine and see if it stays stable.
if not, I'll just add his decoding the bytes data

kind of nice using any button on the remote

Main:
PULSIN PORTB.0,0,LEADER ' leader pulse is ~9mS low-going
IF Leader < 850 THEN
LOW PORTB.2
LEADER = 0
GOTO Main
ENDIF

and yes, could have used else but so simple just wanted to see if functions.
