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
