SOUND command and variable array

[flotulopex]

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].

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

...

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.

Hi, Flotul

Just remember the same things must have EXACTLY the same name ...

I do not know if brackets and parenthesis (?) really work the same manner ... but manual says "Brackets" !!! ... so let's write Brackets !!!

no bad surprises involved ...

Thank you for pointing this out.

Manual shows "brackets" and this is maybe why I wanted to try with parenthesis too

Again, there is almost anything needed in the manual - same as in the data-sheets.

Unfortunately, it is not always comprehensible for beginners like me.
