Vibration analysis - High data rate logging to SD card

Hi everyone,

Has there been any development with regard to logging raw IMU data at data rates 500Hz or higher? Currently the highest data rate is ~250Hz when using the high speed SD log setting. The motor RPM at hover is approximately 8500 RPM so the fundamental frequency that we expect to see in the Output Actuator FFT plot is 140Hz which is not quite half of the sampling frequency.

We’re using the latest stable release (v1.10.0) on the Holybro Pixhawk4 mini
