Andy Piper 7d36bc4422 AP_GyroFFT: new FFT library for motor peak analysis using HAL DSP abstraction ... add dynamic gyro windows control inclusion based on HAL_WITH_DSP and GYROFFT_ENABLED target appropriate ARM cpus constrain window sizes to be achievable improve FFT signal accuracy through configurable window overlap and quinn's estimator calculate energy weighted center frequency add support for learning hover frequency and throttle reference calculate power spectrum rather than amplitude record noise as a per-bin power spectrum calculate true SNR per-bin and use that to determine there is a signal add user config for SNR signal level constrain frequency scanning to MAXHZ calculate and learn the peak bandwidth at the configured attenuation allow enabling/disabling dynamically through rc function MAXHZ should be below Nyquist Incorporate full range of MAXHZ to MINHZ update FFT analysis in a separate thread allocate memory in a specific region constrain window size by CPU class do not allocate any resources when not enabled Prevent self-check and analysis interfering with each other put configuration and initialization to AP_Vehicle add logging fix significant issues with threading, locking and sample buffer access use both calculated noise peaks together with the harmonic notch configuration to detemine which peak represents the fundamental harmonic that should be tracked record harmonic fit add CMSIS 5 libraries and headers allow larger FFT lengths on Linux and SITL		5 years ago
