FFT on Pixhawk V6X

Hi,

Can anyone explain to me that why CUAV Pixhawk V6X doesn’t have the **IMU_GYRO_FFT_EN ?

Is this FC incapable of running the FFT? I need to use the Dynamic Notch filter with FFT since I don’t get RPM from ESCs.

You can’t really expect a proper answer without at least mentioning what PX4 version you’re using.

Provide this context, and a full parameter list would also be helpful for others to help you.

Hi,

Just using the latest 1.17 flashed through the QGC.

I just found out the problem is it’s not enabled in default. I just enabled it and the program size exceeds the flash size of this FC. So, I guess that’s why it’s not available default.
