I'm trying to do a 2048 pt real FFT using fft6713.c as my reference code. When I tested this code with a CD music, (fs changed to 44.1KHz) I realize some of the samples from the ADC were overwritten while the FFT is being done (Obviously I can't do the FFT process in one sample time) Is there a way to store samples from the ADC and do the FFT prcoessing simultaneouly on the C6713 DSK. The mai...

Hello - The ADC on the codec on the C6713 DSK multiplexes "mic" and "line" inputs. That is, you generally set the codec to grab samples from the mic input or the line input, which gives you two analog inputs - the left and right channels. Is there a fast way to "strobe" the line and mic inputs - using the existing HW on the C6713 DSK board - so that I can effectively get 4 analog inp...

Hi I am new to DSP kit and we are implementing our final year degree project on the DSK. DSP kit is little indian by default and we have to interface it with AD9220 (ADC) with Bit 12 (LSB) and Bit 1(MSB). There are 32 data pins in the EMIF of C6713, from data pin 0 to data pin 31. However i am very much confused about which one is the MSB of the DSK. How should we connect the ADC with the DSk. ...

Most of the pins sit high although a few are low (1,3). None alter state when using pinWrite() or Write(). > Proble

The Samplefreq is 48KHz and the Buffersize 128Samples. I am not sure if the right answer is 128/48000=2.66ms or 2*128/48000=5.33ms. Thanks
