I'm plotting the values of the iChannel0LeftIn in the sample audio codec talkthrough but i'm receiving an erroneous output. For example, when i input a pure sine wave using an audio generator to the audio-in of the ezkit, the plotted figure in iChannel0LeftIn is not a sine wave. Do any of you guys know why i'm not receiving the output of the adc properly?
Memory: Blackfin Memory
Address : iChannel0LeftIn
... for my plot configuration.
I think i should receive a sine wave because the iChannel0LeftOut has values coming from the iRxBuffer1 who has values coming from adc ouput.
Can anyone please tell me why the output is not a sine wave? And if ever how can i get to plot the sine wave that i am inputting to the audio-in of the ezkit?
I appreciate any repilies from you guys. Please help..
