Applications
The basic usage of u8glib library's sample program
Note：core's IIC interface is A4（SDA），A5（SCL），core+'s IIC interface is D20（SDA），D21（SCL）
- put your downloaded library into library fold within the Arduino IDE's installation folder. If opened Arduino IDE, please close all other example program before you open example program within u8glib library;
- Open the HelloWorld sample program, remove comments for this line: U8GLIB_SSD1306_128X64 u8g (U8G_I2C_OPT_NONE) (remove "/ /"), then the compiler it,downloaded it directly. After download, you can see the "Hello World!" displayed on the screen;
- Display character / variables:
- Use u8g.print (xx) function, just like use 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 middle 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：
- Post u8g.setRot180() in void setup() function, the screen will flip 180 degrees, you also can change 180 to 90,270;
