Arduino Zero Pro in Max/Msp

Rafal Zalech's icon

Hello everyone,

I just bought a new arduino zero, i get the numbers on serial monitor in arduino.app but nothing in max/msp. I read already tons of infos about serial communication, tried almost everything - no luck. Exactly the same code, same script etc works perfectly on my arduino due, and uno board.

Any arduino freak who could help? :)

Thanks!

Hi,
in the meantime i managed to solve the problem!

In order to start serial communication on ARDUINO ZERO PRO (M0 Pro) you need to enable DTR mode otherwise you won't get any data transfer.

Here a simple code both for arduino and max :

Arduino Zero Pro :

void setup() {
Serial.begin(57600);
}
void loop() {

int sensorValue = analogRead(A0);

Serial.println(sensorValue);
delay(1);
}

Max:
