Tool/software: Code Composer Studio
The else statement is not being invoked. The led 0 continues to be on even though the DIP switch is not toggled. Also, the headphone port is not producing any sine wave. When I connect a headphone jack to it I hear sounds only when i press the stop button in the debug window. I also see about 39 warnings, not really sure why they are being there. Attached is the screenshot of it. so Copied is the code I was trying to run. Can someone help me with this? I am using a Windows 7 OS with CCS V 5 3.

DSK6713_DIP_init(); //init DIP from BSL

if(DSK6713_DIP_get(1)==0) //=0 if DIP switch #0 pressed
{
DSK6713_LED_on(0); //turn LED #0 ON
output_left_sample(sine_table[loopindex++]*gain); //output sample
if (loopindex >= LOOPLENGTH) loopindex = 0; //reset table index
}
else DSK6713_LED_off(0); //turn LED off if not pressed
} //end of while(1) infinite loop
} //end of main
