I try to compute a signal with the FFT. The signal is received over an ultrasound sensor and is attached to ADC on the microcontroller.
Now my problem is when I use the function dfr16RFFT it doesn't work correctly
dfr16RFFT (pRFFT, pX, &zRFFTBuf);
I start the program and it jumps into the function "dfr16bitrev.asm". it stays there and does not come out any more.
This is the code where the program stops:
********* dfr16bitrev.asm ************
sub y0,d ; d=d-y0
asr y0 ; y0=y0/2
cmp.w y0,d ; Check if d>=y0
bge chk_again ; If yes,check again
CodeWarriori version 8.0
