prepare()

The prepare() function is an optional function that is called at the very beginning of a sketch, before any units are initialized. Use it when you need to perform operations that must happen before Plaquette units call their begin() methods, typically when using non-Plaquette objects or functions that need to be built or configured before units are initialized.

Tip

In Plaquette, function prepare() is rarely used and is optional: only declare it if you need to perform operations before units are initialized.

Example

#include <Plaquette.h>

AnalogIn sensor(A0);
DigitalOut led(13);

void prepare() {
  // Early setup before units initialize.
  Serial.begin(115200);
}

void begin() {
  // Runs after units are initialized.
  sensor.smooth();
}

void step() {
  sensor >> led;
}
