Writing code

Controller syntax

In these controllers, code can be written to translate certain controls.

...

• assignment statements

• if and if-else statements

• switch statements

• comments : single line (//) and multiline (/*...*/)

• operators :

  • increment operators (++ and --)

  • unary operators (- and !) 

  • binary operators : power (^), multiply (*), modulo (%), divide (/), sum (+), min (-)

  • ternary operator (a = x ? b : x)  see https://www.freecodecamp.org/news/c-ternary-operator/

  • conditional operators (|| and &&)

  • comparison (<=', >=, >, <, ==, '!=)

  • mathematical functions :  exp, ln, sin, cos, sqrt, min(x1, x2), max(x1, x2)

Initialisation

When using a variable that has not been defined before, the controller will equal the new variable to 0. This functionality can be used for initialisation purposes with the following topology:

Built-in simulation variables

The following built-in parameters variables can also be used without explicit definition in the code withour prior assignment in the programmeable controller:

• time : the time variable of the simulation

• timestep: the timestep of the simulation
