Easy goto question!

BubbaJoeLouis

Greetings,

Sorry to ask a basic basic stamp question, but why does my goto not work unless I have a debug statement?

' {$STAMP BS2}
OUTPUT 7
beginagain:
DEBUG CLS
TOGGLE 7
PAUSE 200
GOTO beginagain

Causes my LED to blink whereas without the clearscreen command:

' {$STAMP BS2}
OUTPUT 7
beginagain:
TOGGLE 7
PAUSE 200
GOTO beginagain

Does nothing. Some info:

Parallax Editor version 2.1
Basic Stamp 2 version 1.0

Thank you!

Not sure. Better coding would put that in a do...while loop and add an END:

' {$STAMP BS2}
' {$PBASIC 2.5}
OUTPUT 7
DO
TOGGLE 7
PAUSE 200
LOOP
END

May be better coding, but the issue remains the same [noparse]:([/noparse]

' {$STAMP BS2}
' {$PBASIC 2.5}
OUTPUT 7
DO
DEBUG CLS
TOGGLE 7
PAUSE 200
LOOP
END

is required to actually get a blink.

' {$STAMP BS2}
' {$PBASIC 2.5}
OUTPUT 7
DO
TOGGLE 7
PAUSE 200
LOOP
END

Does nothing. Also, it doesnt matter if I DEBUG CLS or DEBUG "Yo" it will work. But no debug, no service.

Would you be using a laptop?· This problem has been known to happen on certain laptops, due to serial port issues.· Putting the DEBUG statement in helps to keep the port open, I believe.



If you are using a laptop, this thread covered this as well...

Thats it! It actually started blinking as it should as soon as I pulled the com cable out. I have switched it to a desktop i have now it is acting normal.

Thanks for being my GOTO guy!
