Hi,
I'm doing CapSense proximity sensing. Since I need information about the distance, I work with the sensor raw data. This works well. The only disadvantage is that the the raw data has some noise on it (if necessary, I can provide data). To get rid off the noise, I use the DFT block to process the CapSense raw data values. However, it seems that it's hard to setup the DFB the right way.
On a first thought, I think I need something like a FFT on the data, with only the DC bin as returned value. Is a FFT possible with the DFB? If not, how can I figure out how to setup the DFB to clean the noise out of the signal?
Regards,
Ralf
