SerIn Looping problem ???

[Melanie]

Your program is not looping when there is no Data.

It is suspended, sitting at SERIN waiting for valid Data to arrive. If Data never arrives, it will be there until the end of time or until you forget to pay your electricity bill (whichever comes first).

SERIN has the ability to wait suspended like this for a TIMEOUT period, and if no Data arrives within that given period to jump out to a LABEL elsewhere into your program.

Thanx Melanie (ladies first) & Dave, i didn't know that the SerIn behaved like that with lack of data.

Ok, i'll go fiddle my code to accomodate that, and see what happens ;-)

Thanx again.

Hi again,

For a quick test, i tried :

SerIn pin1,T9600,[1000],SerialData

but nothing happens. (assuming a 1000ms timeout).

Am i meant to be adding other code to accomodate the elapsed timeout? or does the SerIn just "let go" after 1000mS, and return back to any previous gosubs/code etc?


Once again, the PBP Manual is "light" with information in most of it's commands, i'd love to see an entire re-write someday.

Is there an ADVANCED PBP link/pdf i should be looking at these days???

Regards,
Marty.

Loop:
SerIn pin1,T9600,500 Jumpout,SerialData 'get serial data from Pin1,
'store it in variable "SerialData"
Jumpout:

SerOut pin2,T9600,[SerialData] 'send the variable to a terminal to
'view the variable value on screen.

GoTo Loop 'do it forever.

The added code in red, wait for 500 ms the data, then jump to label JUMPOUT executing the serout command.

Thanx AL, i discovered that just moments ago, and got it to work pretty much the same as you've indicated....
