128: signed 5.11 fixed point
Data
elements are signed 16 bit integers representing a real number with
5 bits for the integer component and 11 bits for the fractional component.
The
fixed point representation is equal to the real value multiplied by 2^11.
The
representable range is from -16.0 to 15.9995 (15 + 2047/2048).
Data
types 129 through 255 are available for device specific purposes.
Operation type (uint8)
The operation type specifies what action to perform on the specified
parameter. Currently defined values are:
0:
assign value
The
supplied values are assigned to the specified parameter. Each
element will be clamped according to its valid range.
A
void parameter may only be
“
assigned
”
an empty list of boolean type.
This operation will trigger the action associated with that parameter.
A
boolean value may be assigned the value zero for false, and any other
value for true.
1:
offset / toggle value
Each
value specifies signed offsets of the same type to be added to the
current parameter values.The resulting parameter value will be clamped
according to their valid range.
It
is not valid to apply an offset to a void value.
Applying
any offset other than zero to a boolean value will invert that value.
Operation
types 2 through 127 are reserved. Operation types 128 through 255
are available for device specific purposes..
Data (void)
The data field is 0 or more bytes as determined by the data type and number
of elements.
The
category, parameter, data type and operation type partition a 24 bit operation space.
