setTimeout

I connected a speaker I ripped out of a old cellphone and connected it between pin C8 and 3.3 V.
I can get sound from it by

analogWrite(C8, 0.1 , {freq : 500})

But when I try to create short sounds it's not cooperating.
Should this not send the sound to the speaker in 0.1 seconds?

setTimeout(function () {analogWrite(C8, 0.1 , {freq : 500})}, 100);

What am I doing wrong?

Ok, I got it!!
After reading the reference again slower I understood what I was doing wrong.

200 ms second sound:

setTimeout(function() {analogWrite(C8, 0.5 , {freq : 2000})}, 0)

setTimeout(function() {analogWrite(C8, 0)}, 200)

Great! glad you got it sorted!

Minor thing, but to turn the speaker off you could use digitalRead(C8); instead - that'll put the pin back into an 'input' mode - so if for instance you'd connected the speaker between C8 and VCC then it would ensure that it was actually turned off.

I still can't understand the sence of the first setTimeout.
Why not write:

analogWrite(C8, 0.5 , {freq : 2000});
setTimeout(function() {digitalRead(C8);}, 200);

?
And why code

setTimeout("print(1)",2000);
setTimeout("print(2)",1000);

prints
1
2
without delay?

Yes, writing:

analogWrite(C8, 0.5 , {freq : 2000}); 
setTimeout(function() {digitalRead(C8);}, 200); 

would work fine.

I just tried the code exactly as you suggested, and it writes ....2....1 with a 1 second delay between them as expected. Perhaps you could explain exactly how the code is being used? Is it possible that when you tried it you didn't have the quotes?

Weren't there some firmware versions recently where timekeeping was not working correctly?

I think time-keeping in general was broken on a bunch of my bigram builds (from nov 11 to mid/late december) - were you using one of those?

Well, if you set a timeout on onInit then saved it, you could have problems with some builds. But I'm not sure that's what @user51876 is doing - he definitely didn't suggest he'd done anything like that.
