+# Force Feedback Effects - Thrustmaster T300RS (incl. PS3/PS4 modes)
+Here I will gather all info I can find out about the different force feedback effects and their USB commands. All values seem to be little-endian. Also, general note, it seems like some effects are affected by the direction of the force, denoted by ``***``. As far as I can tell, ``fade_level`` and ``attack_level`` values are calculated by mapping the ``u16`` into ``s16`` and taking the absolute value, and after that multiplying by the direction.
+
+> **NOTE:** All values are examples of actual commands that I captured on the USB interface, not the only available ones.
