Andy Piper	e2ef0bd36e	AP_HAL: collect data for three largest peaks ... new dsp peak detection algorithm add DSP sketch with frequency ascii art tool to generate gyro data frames from batch sampled DF logs add generated data from real Y6B flight allow fft_start() to use ObjectBuffer<float> for lock-free access allow ObjectBuffer to be resized	5 years ago
Andy Piper	509341957f	AP_HAL: check for div0 in quinn's estimator	5 years ago
Andy Piper	f4a99a1589	AP_HAL: hardware abstraction for FFT. ... control inclusion of FFT based on HAL_WITH_DSP and HAL_GYROFFT_ENABLED. target appropriate ARM cpus define hanning window and quinn's estimator start/analyse version of FFT to support threading allocate memory in a specific region calculate frequency and noise bandwidth of two noisiest peaks control inclusion of DSP based on board size	5 years ago
