NAME

       comp - Two input comparator with hysteresis

SYNOPSIS

       loadrt comp [count=N|names=name1[,name2...]]

FUNCTIONS

       comp.N (requires a floating-point thread)
              Update the comparator

PINS

       comp.N.in0 float in
              Inverting input to the comparator

       comp.N.in1 float in
              Non-inverting input to the comparator

       comp.N.out bit out
              Normal output. True when in1 > in0 (see parameter hyst for details)

       comp.N.equal bit out
              Match output.  True when difference between in1 and in0 is less than hyst/2

PARAMETERS

       comp.N.hyst float rw (default: 0.0)
              Hysteresis of the comparator (default 0.0)

              With  zero  hysteresis,  the  output  is true when in1 > in0.  With nonzero hysteresis, the output
              switches on and off at two different values, separated by distance hyst around the point where in1
              = in0.  Keep in mind that floating point calculations are never absolute and it is wise to  always
              set hyst if you intend to use equal
