Reduce the memory usage of your Arduino sketch up to 90% by using the Arduino Port Manipulation.

All references to the ports used by the microcontroller can be found in its datasheet, e.g. Atmega328P.

Attention: the use of this tool on your sketch could make it to lose portability between the different Arduino microcontrollers

For launching this software you need:

• Java 11

The program is designed for the simplest user experience.

All you have to do is:

• select your Arduino's code file
• select the plugins you want to use
• select the board
• click "Optimize" and enjoy

A more detailed guide can be found in /docs/manual directory (Ongoing)

With the classic blink code:

void setup() {
  pinMode(LED_BUILTIN, OUTPUT);
}

void loop() {
  digitalWrite(LED_BUILTIN, HIGH);
  delay(1000);
  digitalWrite(LED_BUILTIN, LOW);
  delay(1000);
}

we have 1460 bytes used.

But, replacing pinMode() and digitalWrite() functions with the relative port manipulation instruction:

void setup() {
  DDRB |= (1<<DDB5);
}

void loop() {
  PORTB |= 00100000;
  delay(1000);
  PORTB &= 11011111;
  delay(1000);
}

we only have 854 bytes used in memory, 42% less memory used.

And, if we replace the setup() and loop() functions with the main() function:

int main() {
  DDRB |= (1<<DDB5);
  
  while(true) {
    PORTB |= 00100000;
    delay(1000);
    PORTB &= 11011111;
    delay(1000);
  }
}

we have only 618 bytes used, 58% less memory used.
