==Applications==
basic usage sample program of u8glib library

Note：core's IIC interface is A4（SDA），A5（SCL），core+'s IIC interface is D20（SDA），D21（SCL）

*put your downloaded library in to libraries within Arduino IDE installation folder, If open Arduino IDE, please close all other example program before you open example program within u8glib library;
*Open the HelloWorld sample program, cancel comment for this line: U8GLIB_SSD1306_128X64 u8g (U8G_I2C_OPT_NONE) (remove "/ /"), the compiler can be downloaded directly through after the download is complete, then "Hello World!" Is displayed on the screen;
*Display character / variables:
*Use u8g.print (xx) function can be, usage are basically as same as Serial.print (xx).
*Change the font：
*Use u8g.setFont (xx) function to change the font, parentheses "xx" can be replaced by the corresponding font library name (you can search font library in u8g.h within U8glib \ utility folder);
*Recommended large font: u8g_font_7x13, recommended font: u8g_font_fixed_v0r, recommended small fonts: u8g_font_chikitar;
*Change coordinates:
*Use u8g.setPrintPos (x, y) function, if you want to change the display coordinates
*Screen Rotation：
*Comment u8g.setRot180() in void setup() function, you flip the screen 180 degrees, you can also change 180 to 90,270;
