Daniel Agar	1b5e65df04	gyro_fft: change default length 1024 -> 512 to decrease latency ... - change default FFT length (1024 -> 512) - this doubles the update rate because half the number of samples are required for each - decrease number of peaks (4 -> 3) - so far 3 seems to be sufficient on most vehicles - increase median filter window (3 -> 5) - decrease SNR requirement (likely needs to be configurable)	2021-07-06 21:54:18 -04:00

Daniel Agar	614a0ac2a2	experimental/gyro_fft: improve peak detection, add start parameter ... - add new parameter `IMU_GYRO_FFT_EN` to start - add 75% overlap in buffer to increase FFT update rate - space out FFT calls (no more than 1 per cycle) - increase `IMU_GYRO_FFT_MIN` default - decrease main stack usage	2020-10-25 23:48:21 -04:00
Daniel Agar	f557fa46e8	gyro_fft improve peak finding, parameterize min/max frequencies, remove debug logging ... - add min/max frequency parameters for peak detection (IMU_GYRO_FFT_MIN, IMU_GYRO_FFT_MAX) - remove full FFT debug logging - fix Quinn's second estimator - log sensor_gyro_fft - fake_gyro use PX4Gyroscope	2020-10-12 15:19:39 -04:00
Daniel Agar	8ee0c62e57	examples: add Gyro FFT using CMSIS 5 on Cortex-m (#15104) ... - this is a work in progress experiment to compute real time FFTs from raw gyro FIFO data on Cortex-m hardware (stm32f4/f7/h7, etc)	2020-10-02 11:47:27 -04:00
