Example code:

#include <Arduino.h>
void setup() {
  Serial.begin(9600);
  #if ((F_CPU) == 1000000)
  #warning F_CPU = 1MHz
  Serial.println("1MHz");
  #elif ((F_CPU) == 2000000)
  #warning F_CPU = 2MHz
  Serial.println("2MHz");
  #elif ((F_CPU) == 4000000)
  #warning F_CPU = 4MHz
  Serial.println("4MHz");
  #elif ((F_CPU) == 8000000)
  #warning F_CPU = 8MHz
  Serial.println("8MHz");
  #elif ((F_CPU) == 16000000)
  #warning F_CPU = 16MHz
  Serial.println("16MHz");
  #elif ((F_CPU) == 32000000)
  #warning F_CPU = 32MHz
  Serial.println("32MHz");
  #endif

  #if ((CLOCK_SOURCE) == 1)
  Serial.println("internal clock");
  #elif ((CLOCK_SOURCE) == 2)
  Serial.println("external clock");
  #endif

  while(1);
}

// the loop function runs over and over again forever
void loop() {
}

Example output:

--- Available filters and text transformations: colorize, debug, default, direct, hexlify, log2file, nocontrol, printable, send_on_enter, time
