FFT:reference,example IIR:reference,example FIR:reference Vector math operations:reference Kalman filter:reference Many of the library functions are written in assembly and are optimized for the CPU configuration used in the ESP32. In addition to the optimized implementations, reference implementations wr...
The above image is my FFT's output for an input frequency of 125Hz I've tried a Hanning window before and after the FTT but the issue still persists. I've really been struggling with the ESP-DSPs lack of documentation, does anybody have experience that could share some advice?Developer...
However, I have a problem with the dsps_tone_gen_f32 function and the FFT. In the example, the dsps_tone_gen_f32 function is used to generate two signals, and I modified it to work with only one signal. But when I applied the FFT, the result didn't match the signal. I sent ...
