STRUCT
FF_PERIODIC_E(9) Input Subsystem STRUCT FF_PERIODIC_E(9)
NAME
struct_ff_periodic_effect - defines parameters of a periodic force-feedback effect
SYNOPSIS
struct ff_periodic_effect { __u16 waveform; __u16 period; __s16 magnitude; __s16 offset; __u16 phase; struct ff_envelope envelope; __u32 custom_len; __s16 __user * custom_data; };
MEMBERS
waveform kind of the effect (wave) period period of the wave (ms) magnitude peak value offset mean value of the wave (roughly) phase 'horizontal' shift envelope envelope data custom_len number of samples (FF_CUSTOM only) custom_data buffer of samples (FF_CUSTOM only)
DESCRIPTION
Known waveforms - FF_SQUARE, FF_TRIANGLE, FF_SINE, FF_SAW_UP, FF_SAW_DOWN, FF_CUSTOM. The exact syntax FF_CUSTOM is undefined for the time being as no driver supports it yet.
NOTE
the data pointed by custom_data is copied by the driver. You can therefore dispose of the memory after the upload/update.
