Hello again,

I am searching for some kind of "info" whether it is possible to detect if the "play wav" (or any other audio output) is still playing.

Reason for that is obvious: everytime I do something like:

Play wav "myFile"

I have to know exactly how long this will take before I can retrigger this event. Otherwise I get ERRORs because it is still playing. To solve this I can:

Pause

play with

If Timer...

or even deactivate ERRORs via

ON ERROR

(yes this is an awful way! I don't use this!)

IDEA for a possible solution:
------
In my other Arduino / Atmega328p projects I used an external player with an SD card which indicated the "still playing" state via an LED, so I just read this led out whether it is still "HIGH", if not: retrigger - done, problem solved.

I guess this could be solved by Peter via internal commands like: Info("audio output") or some kind?

I think this is an really important feature... Or am I blind and this is already possible?

Edit: I am using latest PicoMite beta. And ...Wouldn't it make more sense to start all over again if an already "playing wav" is executed (again), before it is finished, instead of throwing an error and stopping the whole program?

SORRY! Found it in the manual, just need to try it:
"...interrupt is optional and is the name of a subroutine which will be called when the
file has finished playing."

Greetings
Daniel

You can take control by using a Flag..

Quote
PLAY WAV file$ [, interrupt]
The WAV file is played in the background. 'interrupt' is optional and is the
name of a subroutine which will be called when the file has finished playing.

use subs to controll this makes it easy

'---play a wave
sub Wave file$
if not playing then playing=1:PLAY WAV file$ ,nosound
end sub
'----end playing
sub nosound
playing=0
end sub

you call it with "Wave nameofyourfile$"
the Flag "playing" returns, if there is allready a wave plaing in the Background

you edited it, while I was typing the anwer

This was my first idea, but it isn't mentioned in the whole manual. I've searched for it again. Nothing.

But now I am aware of it

and thank you Martin for posting an example code.
