ddt

NAME

ddt - Compute the derivative of the input function

SYNOPSIS

DESCRIPTION

For every function call from the real time thread, calculate the difference between the old and current input value divided by the timer elapsed since the last call.

FUNCTIONS

ddt.N (requires a floating-point thread)

PINS

ddt.N.in float in

 

ddt.N.out float out

NOTES

As this only work on two consecutive input values, it will only work well if the input change every function call, and not work so well if the rate of change is very low and the input change do not happen every time the real time function is called.
