Wireless Comunication Dilemma

[Jerson]

Hello Again,
rx:
serin rxpin,n1200,[$66],VALID,UTYPE,UID
if VALID = 22 then hit
goto rx

hit:
</code>

Jeremy

After a cursory glance at your code, I think the statement in RX should change to

rx:
        serin rxpin,n1200,[WAIT($66),VALID,UTYPE,UID]

Wait for $66 and then read the rest.

Hey Jerson,
I tried changing the the code but for some reason when i try to compile the code, the following error occurrs. <code>ERROR Line 25: Bad expression. (RX.pbp)</code>

<code>rx:
serin rxpin,n1200,[WAIT($66),VALID,UTYPE,UID] 'Line 25
if VALID = 22 then hit
goto rx</code>

Is it the software i am using?
MicroCode Studio - PBP Compiler

The previous code works using RF modules but not for IR.

Regards,
Jeremy

Double check the syntax for SERIN and the wait modifier.

Other than that, are you sure the hardware is working correctly, everything is matched?

If you have not seen this it may help. The receiver code is for a BS2 though.

See this example http://www.rentron.com/Micro-Bot/IR_Serial.htm

SERIN does not require the WAIT modifier. Just enclose the qualifier in square
brackets. SERIN2 can be used with the WAIT modifier followed by the qualifier
in square brackets.

Thanks Guys,
I have been looking around at different posts and the internet and i can't find a solution, they all say what i am doing is correct but it does not work. I have attached a copy of the wiring for you guys to look at. The only other thing i can think of in the Baud Rate and the way its driven. Should N1200 work? or should i drive it TRUE?

Thanks Again,
Jeremy

Your drawing will not display. Try uploading again.
