void update(void) {
	OLED_drawPixel(0, 0, 1);
	char str[] = "Hello World!\n";
	OLED_print(&str);
	OLED_update();
}

int main(void)
{
	Delay_Init();
	USART_Printf_Init(115200);
	printf("SystemClk:%d\r\n",SystemCoreClock);
	
	// Setup internal peripherals
  I2C_init();

  // Setup external peripherals
  OLED_init();
  OLED_clear();
  update();

  Delay_Ms(500);
}
