→setup()
* '''setup''' : function setting-up the hardware of your DIN project. Called function receives ''din'' object is as parameter.
* '''setup''' : function setting-up the hardware of your DIN project. Called function receives ''din'' object is as parameter.
* '''loop''' : async function executing the ''userloop'' code. The ''din'' object is received as parameter. Called function receives the ''din'' object as parameter.
* '''loop''' : async function executing the ''userloop'' code. The ''din'' object is received as parameter. Called function receives the ''din'' object as parameter.
* '''on_task_create''' : callback event
* '''on_task_create''' : callback event allowing the user code to insert its own project tasks.
The exemple here below shows how to create the ''userloop'' and the ''setup'' function.
