Okay here is one for you... I just realized this is in the window at the bottom of the Ardiuno IDE when I upload the code.
C:\Users\Jim\AppData\Local\Temp\arduino_modified_sketch_772442\HelloWorld.ino: In function 'void setup()':
C:\Users\Jim\AppData\Local\Temp\arduino_modified_sketch_772442\HelloWorld.ino:14:31: warning: deprecated conversion from string constant to 'char*' [-Wwrite-strings]
vfd.write("1234567890ABCDEF");

Sketch uses 1304 bytes (4%) of program storage space. Maximum is 30720 bytes.
Global variables use 96 bytes (4%) of dynamic memory, leaving 1952 bytes for local variables. Maximum is 2048 bytes.
But it still uploads. This happens when using this:
#include <vfd_vaf1613.h>
//adjust these according to your wiring:
const byte clockPin = 7;
const byte dataPin = 5;
const byte resetPin = 6;
VFD_VAF1613 vfd(clockPin, dataPin, resetPin);
void setup()
{
vfd.init();
vfd.power_on();
vfd.write("1234567890ABCDEF");
}
void loop() {
}
