Hi.
I get your wav player project.
I'm trying to use it with a P184620@8Mhz (PLLx4).
It seems to work, but i often see the buffer full LED on, and no rilevant wave sound out of the DAC.
It seems a problem with the interrupt.
What can i check ?
Another question Timer1 is in counter mode or timer mode ?

Thank you for your support.
Sorry for my poor english, i speak Italian.

Bye

Hello. Thanks for your post. Are you getting any sound at all, or is there complete silence? Have you put together your own hardware, or are you using a development board? Timer1 is being used as a timer, interrupting on overflow.

i can see something with oscilloscope but it isn't sound :( .
I do this player with my own HW, following the requirements shown in the article...
