SYNOPSIS

};
 

MEMBERS

value

latest reported value for the axis.

minimum

specifies minimum value for the axis.

maximum

specifies maximum value for the axis.

fuzz

specifies fuzz value that is used to filter noise from the event stream.

flat

values that are within this value will be discarded by joydev interface and reported as 0 instead.

resolution

DESCRIPTION

Note that input core does not clamp reported values to the [minimum, maximum] limits, such task is left to userspace.

Resolution for main axes (ABS_X, ABS_Y, ABS_Z) is reported in units per millimeter (units/mm), resolution for rotational axes (ABS_RX, ABS_RY, ABS_RZ) is reported in units per radian.
