SOUND command and variable array

[mat janssen]

That is not what I typed.
Did you give "speaker" a portnumber?

Hi, Flotul

What about Vsnd[A] instead ( Vsnd(A) or Vsnd.A ) ???

Did you also check the tones are compatible with your speaker bandwidth ???

just a thought ... for High audio frequencies.

mat janssen,

Don't worry: I copied/pasted your example "as it is" and it didn't work. I then posted another try I made. Sorry for the confusion.

I tried with both brakets or parenthesis; never works....

Yes, the sounds can be made correctly when not in this kind of referencing loop.

Still searching.

Tried Brackets Here also ???

Vsnd.0 = 121
Vsnd.1 = 120
Vsnd.2 = 119
Vsnd.3 = 116


Vsnd.0 is bit 0 of Byte Vsnd ( which is also different from Vsnd[A] !!! ) ... can't work properly here !!!

Acetronics,

I'm not sure to understand your remark.

I tried this:
SOUND Speaker,[Vsnd(A),10]
and
SOUND Speaker,[Vsnd.0(A),10]
and
SOUND Speaker,(Vsnd[A],10)
and
SOUND Speaker,(Vsnd.0[A],10)

In fact, I get a sound but it is a much lower frequency than compared to when I play the sound like SOUND Speaker,[121,10].

[Acetronics2]

Tried THIS ???
...

Vsnd var byte [4]

Vsnd[0] = 121
Vsnd[1] = 120
Vsnd[2] = 119
Vsnd[3] = 116

FOR A = 0 to 3
SOUND Speaker,[Vsnd[A],10]
NEXT A

...

Acetronics,

I'm not sure to understand your remark.

I tried this:
SOUND Speaker,[Vsnd(A),10]
and
SOUND Speaker,[Vsnd.0(A),10]
and
SOUND Speaker,(Vsnd[A],10)
and
SOUND Speaker,(Vsnd.0[A],10)

In fact, I get a sound but it is a much lower frequency than compared to when I play the sound like SOUND Speaker,[121,10].

Do you have a cap on the output like the manual suggests? What kind of speaker are you driving? What's you OSC? Which PIC are you using?

speaker var portb.1:a var byte:for a=0 to 255:sound speaker,[a,50]:next a

or maybe:

vsnd var byte[3]:vsnd[0]=10:vsnd[1]=30:vsnd[2]=75:vsnd[3]=120
a var byte:for a=0 to 3:sound speaker,[vsnd[a],50]:next a

Thank you ACETRONICS,

You gave me the correct syntax.

Just to make sure, I tried this that works too:

Vsnd var byte [4]
Vsnd(0) = 121
Vsnd(1) = 120
Vsnd(2) = 119
Vsnd(3) = 116

FOR A = 0 to 3
SOUND Speaker,[Vsnd(A),10]
NEXT A

I personally would have appreciate to see this kind of example in the Compiler's manual instead of bothering you... I read it a few times, but without any clear example, it stayed unclear to me.

Thanks a lot for your help.
