Andy Piper	d3e57be6e5	AP_HAL: save a sliding window array of frequency bins ... calculate frequency average from sliding window	2022-06-01 15:49:32 +01:00
Andy Piper	f57ac4787d	AP_HAL: add Jain's estimator ... notch tuning using FFT averaging allocate scratch space for peak finding return all detected peaks to caller	2022-05-04 17:05:51 +10:00
Peter Barker	a9b90a3b5a	AP_HAL: stop libraries including AP_Logger.h in .h files ... AP_Logger.h is a nexus of includes; while this is being improved over time, there's no reason for the library headers to include AP_Logger.h as the logger itself is access by singleton and the structures are in LogStructure.h This necessitated moving The PID_Info structure out of AP_Logger's namespace. This cleans up a pretty nasty bit - that structure is definitely not simply used for logging, but also used to pass pid information around to controllers! There are a lot of patches in here because AP_Logger.h, acting as a nexus, was providing transitive header file inclusion in many (some unlikely!) places.	2022-04-08 19:18:38 +10:00
