    FFT Noise with XDK

    FFT Noise with XDK


    I am trying (again) to do a FFT Noise analysis with the Bosch XDK. It's my second or third trial...

    I already learned that one member has a personal solution - but unfortunately that one is not publicly available

    The RTOS-Timer theoretically allows 1ms delays for each task. After trying that out I saw that the only realistic value is 10ms. I come to a similar value (about 9ms) when I don't use a timer, but a loop and just try to get the information as fast as possible and write the timer_counter in parallel.

    --> so my first question is - how is it possible to increase the frequency to record samples ? << 10ms --> in the first step, in order to know what I am doing, I also want to store that information on SD-File (e.g. every x samples read into an array). I can write batch of data on the SD card, those samples are taken every ~9ms. 

    --> is there a working solution for FFT with Noise available? - the solution shown on XDK homepage does not show big knowledge regarding FFT of noise, beginning with a timer of 100ms - 10 Hz sampling frequency, which is much too low for analysing noise. Honestly, I don't understand why this webpage on noise was not updated by Bosch as this part is no promotion...
