implemented FFT amplitude dump. Somehow FFT is working, but now it is buggy. FFT results are connected with input signal, but this connection is not straightforward.

FFT is somehow working. FFT results are dumped to the PC as: 0xF1 -- Re, 0xF2 -- Im. But results are still weird: for both sin and DC signals from ADC it returns periodic waves in FFT results.

FFT is correctly calculated for dummy (DC = 1.0) data!

fixed angle and cos generation. Problem was in diffrent declaration of DATA_L and other defines in different files. Solution: fixed include tree

somehow averaging fails (avg cycle stops too early. So in the result of avg there is sum of all runs in the start and some values in line are forbidden at the end of avg cycle). Fixed avg cycle numbering -> averaged value have the same amplitude as raw value

Have been trying to force LARGE array allocation in SDRAM. Due to a bug somewhere in compiler or configuration, arrays defined in l502_user_process.c with '#include l502_sdram_noinit.h' or '__attribute__((section('.sdram_noinit')))' directives (that should allocate array in SDRAM) wrongly allocates in MEM_L1_DATA_A and overfills it. Workaround: define large arrays with these directives in l502_streams.c and include them via 'extern'.
