c6711 DSK and codec

Started by Carlos Eduardo F. de Oliveira November 14, 2001
Hi,
I've try to generate a sine wave with a c6711dsk, but it's not works.
I'm try a lot of examples to configure the codec and when I do something
like that:

in = mcbsp0_read ();
mcbsp0_write(in & 0xFFFE);

works fine (pass the audio in input to output), but if I do it:

out = ((unsigned int) ((y+1)*32767)) & 0xFFFE; /*where y is float and
have values between -1 and 1 (sine values )*/
mcbsp0_write(out);

it's not work.
Anyone had a problem like that or any a idea where I'm wrong?!

Regards,
Carlos Eduardo.
