    Transmitting speech signals!

    ravi.teja

      Hi ,

         

       I am working on digitising our speech signals and transmitting these digital samples using UART to PC and collecting in PC using hyperterminal.

         

       

         

      Problem is am losing many samples. For 16000BPS sampling rate, i collect only 1600 samples per second. 

         

      I have not used a DMA or ISR ,which i suppose, to be an efficient way?

         

      If so could somebody help me with adding the ISR or/and DMA to the present workspace including the C-code?

         

       

         

      If not, is there any other efficient way?

         

       

         

      I have attached my workspace.

         

       

         

      Thanks in advance
