BS2px issue

Toborg

Hello,

I just recieved a BS2px from parallax yesterday. Tried a simple do-loop command:

' {$STAMP BS2px}
' {$PBASIC 2.5}

DO
HIGH 0
LOOP

Here is what happens, I get 4.95v for like a milisecond. then it goes back to .875v

I believe it should be constant. Am I right?

So, here is the wierd part. When I put some other line of code in addition to the High 0 command, it works.

ex:

' {$STAMP BS2px}
' {$PBASIC 2.5}

DO
HIGH 0
DEBUG "."
LOOP

When loading this code, I get a constant 4.95v on my scope.
Plus a debug screen full of periods.............
Any thoughts?



This is my first BS2px. I Have prior to this only used BS2.

Your first example should work as you expect. Check to make sure that your program is entered the way you've shown.

' {$STAMP BS2px}
' {$PBASIC 2.5}
DO
HIGH 0
LOOP

This should also work:

' {$STAMP BS2px}
' {$PBASIC 2.5}
HIGH 0
DO
LOOP

My code was copied and pasted straight in to the forum.

I tried the adaptation that you suggested. The same result of a momentary high on pin 0.

any further suggestions?

Well, its working now!

Silly but, the only thing i did different was a FREQOUT command.

'{$STAMP BS2px}
' {$PBASIC 2.5}
DO
FREQOUT 0,1000,10

LOOP

After that now when I try the other code it works.

Not sure why, but it works now.



Thanks for the help.
