help! trying to send a high from one parallax board to another

Ashley

okay so are project is basically this ir sends signal to reciver that it sees its so
its

if irdetect = 1 then
high 15
endif

then we've connected a wire from pin 15 to another board in pin 6

does it need ground or sumthing? like

if in6 = 1 then
pulsout 13,650
endif

but its not recieving the high for pin6 to make it do what we want
like ive check the wire and used an led and the ir is sending the signal but
pin6 isnt doing anything...

I think an IR Detector has an active LOW signal. Meaning when it detects IR, its output goes LOW.

What's the "PULSOUT" supposed to be doing? If it's a BS2, "PULSOUT 13, 650" will give you a 325 uSec pulse -- that's AWFULLY small.

You may need an "INPUT IRDetect" line -- but probably that's the default...

The pulseout is the code for our motor that we have hooked up to the bored enabling us to lower a door down. we hooked up an led to the 1st bored and it was sending out a signal to high 15 but the other bord won't recieve it to high 6 ... if that makes sence.

instead of high 15 should it be low?

Ashley

okies so it sends the darn signal can someone look at my code?
(board 1)
FOR bridge = 0 TO 220 'bridge opens
DEBUG DEC bridge 'displays amount of time it takes to open
PULSOUT 15,850
PAUSE 100 'waits
NEXT

---

(so in here the ir is sensed on different board sending the signal to pin 6)
(board 2)
DO

FREQOUT 6, 1, 38500
irdetect = IN5
DEBUG HOME, "irDetect = ", BIN1 irdetect

IF irdetect = 1 THEN 'ir detected
HIGH 15 'send high 15 signal to other parallax
ELSEIF irdetect = 0 THEN 'ir not detected
LOW 15 'send low 15 signal to other parallax
ENDIF

LOOP

---

(board 2)

IF IN6 = 1 THEN 'if pin 15 is high then
DEBUG BIN IN6 'displays if working
FOR bridge = 0 TO 220 'bridge closes
DEBUG DEC bridge 'displays amount of time it takes to close
PULSOUT 15, 650
PAUSE 100 'waits
NEXT
ELSEIF IN6 = 0 THEN 'if pin 15 is low then
DEBUG BIN IN15 'displays if working
END 'ends program
ENDIF

woops the second board 2 should be board 1

Amaral

hook the ground of both boards toguether ! just put a wire from ground to ground.

as far as I understand you are not sending any signal thru IR led or detectors ! wright ?


Hope to help
