Pitch shift problems

If you have these settings (specifically the ones related to USB support, and U(S)ART support:

then generic Serial.println should be functioning.

If you’re able to program the Daisy properly from Arduino then it seems you have everything installed correctly, and USB is functioning. Are you able to see the Daisy show up in your Device Manager? From arduino it would show up as a "STM32 Virtual ComPort)

With the above settings, this sketch works without issue:

int val;
void setup() {
  // put your setup code here, to run once:
  Serial.begin(9600);
  val = 0;
}

void loop() {
  // put your main code here, to run repeatedly:
  delay(100);
  val++;
  Serial.println(val);
}
