I am currently working on a Teensy 2.0 Arduino project where I want to either connect the Teensy USB to the computer, or in other scenarios just to a phone Charger (no computer listening to the serial port). Without chaning the sketch in between.
I am now opening Serial like:
If I comment out all the serial stuff my sketch runs just fine with "nothing" (a charger actually) connected to USB. If not it seems to hang in setup().
Is there a "right" or suggested way to solve this problem or should this just work and is my problem somewhere else (a side effect)?
Thanks in advance,
Ralph

Code:
void setup() {
Serial.begin(38400);
while (!Serial)
;
}
...
void loop() {
Serial.print("foo");
// do other stuff
}
