Cant upload to my Arduino Micro board

Using Arduino Avrdude, stk500, Bootloader issues

Hey,

I am trying to upload this code on to my arduino micro board:

// Key definitions
#define BUTTON_KEY1 KEY_F13
#define BUTTON_KEY2 KEY_F14
#define BUTTON_KEY3 KEY_F15
#define BUTTON_KEY4 KEY_F16
#define BUTTON_KEY5 KEY_F17
#define BUTTON_KEY6 KEY_F18
#define BUTTON_KEY7 KEY_F19
#define BUTTON_KEY8 KEY_F20

// Pin definitions
#define BUTTON_PIN1 2
#define BUTTON_PIN2 3
#define BUTTON_PIN3 4
#define BUTTON_PIN4 5
#define BUTTON_PIN5 6
#define BUTTON_PIN6 7
#define BUTTON_PIN7 8
#define BUTTON_PIN8 9
// ---------------------------------

#include "Keyboard.h"

// Button helper class for handling press/release and debouncing
class button {
  public:
  const char key;
  const uint8_t pin;

  button(uint8_t k, uint8_t p) : key(k), pin(p){}

  void press(boolean state){
    if(state == pressed || (millis() - lastPressed  <= debounceTime)){
      return; // Nothing to see here, folks
    }

    lastPressed = millis();

    state ? Keyboard.press(key) : Keyboard.release(key);    
    pressed = state;
  }

  void update(){
    press(!digitalRead(pin));
  }

  private:
  const unsigned long debounceTime = 30;
  unsigned long lastPressed = 0;
  boolean pressed = 0;
} ;

// Button objects, organized in array
button buttons[] = {
  {BUTTON_KEY1, BUTTON_PIN1},
  {BUTTON_KEY2, BUTTON_PIN2},
  {BUTTON_KEY3, BUTTON_PIN3},
  {BUTTON_KEY4, BUTTON_PIN4},
  {BUTTON_KEY5, BUTTON_PIN5},
  {BUTTON_KEY6, BUTTON_PIN6},
  {BUTTON_KEY7, BUTTON_PIN7},
  {BUTTON_KEY8, BUTTON_PIN8},
};

const uint8_t NumButtons = sizeof(buttons) / sizeof(button);
const uint8_t ledPin = 17;

void setup() { 
  // Safety check. Ground pin #1 (RX) to cancel keyboard inputs.
  pinMode(1, INPUT_PULLUP);
  if(!digitalRead(1)){
    failsafe();
  }

  // Set LEDs Off. Active low.
  pinMode(ledPin, OUTPUT);
  digitalWrite(ledPin, HIGH);
  TXLED0;

  for(int i = 0; i < NumButtons; i++){
    pinMode(buttons[i].pin, INPUT_PULLUP);
  }
}

void loop() {
  for(int i = 0; i < NumButtons; i++){
    buttons[i].update();
  }
}

void failsafe(){
  for(;;){} // Just going to hang out here for awhile :D
}

but when I do so it gives me this error message:

Sketch uses 6400 bytes (22%) of program storage space. Maximum is 28672 bytes.
Global variables use 314 bytes (12%) of dynamic memory, leaving 2246 bytes for local variables. Maximum is 2560 bytes.

any ideas how to fix?
Thanks

At the moment that you see the message from the IDE about the memory usage, double tap the reset button.

Which version of the IDE are you using?
