    Play audio sample from external and internal memory

    greg.lőrincz

      I was wondering how does one play samples? The first thing I'd like to achieve is to play a sine wave from a waveform sample. I wonder if I can do that or is there a simpler way?

         

      Store raw audio in EEPROM -> drive DMA with clock or PWM -> pipe DMA output to DAC 

         

      If there are any examples or application notes on this, I'd really appreciate that! Also, can I play audio from external memory (as in SD card)?
