Hi,

I'm using TMS320C6745 for my application which takes 4 channel audio data from an ADC (16 bit AD7606 ) in 2' s complement form through GPIO ports. How to interpret the ADC data and data type in CCS and how to do further processing like FFT calculation?

Hi Venkatesh,

As for interpreting data read from the ADC, you should refer to the AD7606 datasheet (there is a theory of operation & reading data from the digital interface sections).

Regarding FFT, there are dsplibs in Processor SDK RTOS: http://software-dl.ti.com/processor-sdk-rtos/esd/docs/06_00_00_07/rtos/index_dsp_sw.html , which you can use as reference.

Best Regards,
Yordan

In regards to using CCS to interpret/visualize data like FFT, please see section 7.7 of the CCS User's Guide:
