SERIN2 freezes

[xnihilo]

Hello,

Could someone help me out with serin2?

serin2 portA.0,188,3000,toto,[WAIT("$GPRMC")]
works
serin2 portA.0,188,3000,toto,[WAIT("$GPRMC"), STR mystring\10]
does not work (stays stuck in SERIN3

Why is that? I though that it would wait for a string then collect next 10 bytes and store them in the mystring byte array but it doesn't... Why?

THIS does NOT work:


gps:
LCDOUT $fe,1,"in GPS"
LCDOUT $fe,$c0,"Serin start"
PAUSE 2000
'SerIn2 PORTA.0,188,3000,toto,[Wait("$GPRMC,"),DEC2 b1,DEC2 b2] 'works
SerIn2 PORTA.0,188,3000,toto,[wait("$GPRMC"),wait(","),DEC2 hh,DEC2 mm,wait(","),fix,wait(","),DEC2 latdeg,DEC2 latmin,wait(","),NS,wait(","),DEC3 londeg,DEC2 lonmin,wait(","),EO,wait(","),knots,wait("."),DEC2 knotsten,wait(","),DEC3 course,wait(","),DEC2 j,DEC2 m,DEC2 a] 'works
LCDOUT $fe,1,"found"
LCDOUT $fe,$c0,"="
PAUSE 2000
IF fix="V" Then display
goto gps

toto:
LCDOUT $fe,1,"timeout"
PAUSE 2000
GOTO gps

display:
LCDOUT $fe,1,"Data is:"
PAUSE 2000
goto gps

While THIS works:


gps:
LCDOUT $fe,1,"in GPS"
LCDOUT $fe,$c0,"Serin start"
PAUSE 2000
'SerIn2 PORTA.0,188,3000,toto,[Wait("$GPRMC,"),DEC2 b1,DEC2 b2] 'works
SerIn2 PORTA.0,188,3000,toto,[wait("$GPRMC"),wait(","),DEC2 hh,DEC2 mm,wait(","),fix,wait(","),DEC2 latdeg,DEC2 latmin,wait(","),NS,wait(","),DEC3 londeg,DEC2 lonmin,wait(","),EO,wait(","),knots,wait("."),DEC2 knotsten,wait(","),DEC3 course,wait(","),DEC2 j,DEC2 m,DEC2 a] 'works
LCDOUT $fe,1,"found"
LCDOUT $fe,$c0,"="
PAUSE 2000
goto gps

toto:
LCDOUT $fe,1,"timeout"
PAUSE 2000
GOTO gps

WHY?

Hi xnihilo,

I think the problem is about STR, i mean PBP doesn't work well (not a bit) with strings.
But, i have the same problem, SERIN2 freezes when i add a timeout and label of delay. This code doesn't work:




'**
'
'Purpose: How many delays do i have?
'
'**
myRX VAR PORTB.0

myVar VAR BYTE
data VAR BYTE

CALL OnScreen

loop:

SERIN2 myRX,396,100,delay,[wait ("N"),data]

GOTO loop

delay:
myVar=myVar+1
CALL OnScreen
RETURN

OnScreen:
lcdout $fe,1
lcdout #MyVar
RETURN



the code doesn't go to delay label.

Hmmm. Put the blame on the compiler when your code does not work?

Maybe you need to look at the CALL section in the manual.
And that RETURN right after that might not be helping either.

[KaanInal]

Sorry for the misunderstanding :) it was not a blame, i love this compiler. I didn't find any string functions on my sources, if you knew some please tell me so i can change my sources with correct ones. It was an opinion.

It was a part of my code but i don't understand what is wrong with the call? Should i use gosub? What do you suggest ?

Also,
there is an answer on this page: http://www.picbasic.co.uk/forum/showthread.php?t=1944&highlight=idle

xnihilo, is that solves your problem too?

[mackrackit]

No problems :D

The PIC it's self is not really a string type setup, but PBP gives it a good shot by treating strings as an array. The STR modifier is for that. Yes, more string handling might be nice, or a different way of handling them... But we are so limited on memory the way it is with most PICs that it may be a shot in the foot.

CALL -- that is for "CALLING" an ASM function.

The TIME OUT/GOTO label is just that. a GOTO.
So wherever you send things after a serial time out do not use a RETURN.


SERIN2 myRX,396,100,delay,[wait ("N"),data]

GOTO loop

delay:
myVar=myVar+1
CALL OnScreen
RETURN

In the above case replace the RETURN with GOTO LOOP.
Looks like that is what you want....

I got it;) .

Thank you by the way, that explains the "CALL and RETURN overflow" problems on my simulations :rolleyes:.

Glad to bof soivice ;)
