WebFeb 27, 2014 · I was trying to use CMSIS DSP library on the DUE. this library is the file libarm_cortexM3l_math.a (instead of in .cpp source code, like the. run-of-the-mill arduino (user)libraries) the headers for this library are available by including. #define ARM_MATH_CM3 #include . WebNow I trying to use the cFFT in a signal. To the test I created a pure sine wave in an array of 1024 samples (amplitude of 1000 and 10 cycles), as in the image. After the processing the indexer return the correct harmonic (10th), but I don't understand the result of the magnitude. The magnitude of the 10th hamonic is 727.98.

Hi, I replaced the arm_cmplx_mag_q15 () with arm_cmplx_mag_squared_q15 (). Result compared to the output of the f32 CFFT is a ratio between ~980 and ~1061 for the two outputs - so it seems this is working, with a reduced precision and a varying ratio. So, why do I have to use the squared magnitude function ...
