What argument redirection is accepted in serialprint()?

Projects Programming

In using serialprint() function in troubleshooting I have not found what level of redirection is allowed in the argument. It seems that a literal value is needed? number = array[0], serialprint(number) works, but serialprint(array[0]) does not. Does anyone know where to find the documentation of allowed arguments for serialprint() function. The manual is not very explicit on this. I couldn't find anywhere it said an expression that evaluates to a valid data type could not be used.

It would if you used Serial.print(), instead.

If you are having a problem with your code, show it to us. Idle speculation involves beer, which you haven't provided.

Strange. It works for me.

byte array[] = {5, 4, 3, 2, 1, 0, 1, 2, 3, 4, 5};

void setup() 
{
  Serial.begin(115200);
  for (int i = 0; i < sizeof(array) / sizeof(array[0]); i++)
  {
    Serial.println(array[i]);
  }
}

void loop() 
{
}

HardwareSerial.cpp on your PC would be a good place to start.
