==Objective==
Learn the Microduino OLED and master how to use the library to derive the OLED.
==Equipment==
*'''[[Microduino-OLED]]'''
Microduino-Oled is a 0.96 inch 12864 OLED display module based on SSD1306. It uses I2C interface, and 3.3V power. The pixel is 128 * 64 (128 columns * 64 rows).

*'''[[Microduino-Core]]'''

*'''[[Microduino-Core+]]'''

*'''[[Microduino-FT232R]]'''

*Other equipments：
**OLED adapter cable one
**DuPont line four
**USB cable one

==Prepare work==
*【U8glib library'''[http://code.google.com/p/u8glib/ google download ]''' 】
*Put the downloaded library into the libraries folder of the Arduino IDE;
*Open the example program. If you have opened the Arduino IDE, need to close firstly, then open the example program from the u8glib library:
*Connect the OLED to circuit according to IIC connection method.

==Program==
Download program：'''[[File:oled_project.zip]]'''

==Experiment 1==
*Display character, including the specific character and the character changed according to data.
Grammar：
*The first line display "*_*Microduino*_*"；
*The second line display "Time："；
*The third line display time calculated by funcion mills(), use the ms as unit, and map into the second unit, only keep two decimal.
*Grammar：
**u8g.setFont(XXX)uses to set font, no default font, must be defined.
**u8g.setPrintPos(X,Y) uses to set he positon of the specified character,X represents the horizontal position coordinate, Y represents longitudinal coordinates. The Y value can't be 0 in top line, and the value should be greater than the height of the font.
**u8g.print(XXX)uses to display character, static characters need to add " ", no need for change data;
**u8g.drawStr(X, Y,XXX) uses to display specified character, can't display changing data；
**u8g.setRot180()uses to font rotation, rotate character from 180 to 90, 270. The default value is 0;
**Change font and coordinates need to add fonts and coordinate function in front of the display function;
**When change font, need to find the font library in file u8g.h from U8glib\utility folder.

==Experiment 2==
*Draw picture
Open "OLED_Paint" example program, select board type and use the serial to downlaod.
The experiment to realize how to draw a straight line, a solid, hollow, solid rectangular, hollow rectangular, apex angle bending rectangular, the system timing simulate the pointer of second hand.
*Grammar：
**u8g.drawLine(X,Y,M,N) uses to draw a straight line；
***X: starting horizontal position coordinates, Y: the starting point of the longitudinal coordinates, M: end horizontal position coordinates, N: the end of the longitudinal coordinate.
**u8g.drawDisc(X,Y,D) uses to draw a solid:
***X: horizontal coordinates, Y: longitudinal coordinate, D: diameter;
**u8g.drawCircle(X,Y,D) uses to draw a hollow:
***X: horizontal coordinates, Y: longitudinal coordinate, D: diameter;
**u8g.drawFrame(X,Y,I,W) uses to draw a hollow rectangular:
***X: horizontal coordinates, Y: longitudinal coordinate, I: length, W: wide;
**u8g.drawBox(X,Y,I,W) uses to draw a solid rectangular；
***X: horizontal coordinates, Y: longitudinal coordinate, I: long, W: wide
**u8g.drawRFrame(X,Y,I,W,B) uses to draw a apex angle bending rectangular；
***X: horizontal coordinates, Y: longitudinal coordinate, I: long, W: wide

==Experiment 3==
*Display chinese characters, images and dynamic text:

**Display character using library. The images and chinese characters need to modulo then to print.
Modulo software：'''[[File:PCtolCD.zip]]'''

*Take the chinese character as example：

**Make chinese character modulo code：
Step 1：Open the modulo software, select the mode "Character mode"；
[[File:set_1.jpg|800px|thumb|center|Microduino-OLED]]
Step 2：Set font size as 32*32；
[[File:set_2.jpg|800px|thumb|center|Microduino-OLED]]
Step 3：Input chinese character, you can choose font；
[[File:set_3.jpg|800px|thumb|center|Microduino-OLED]]
Step 4：Set modulo format；
[[File:set_4.jpg|800px|thumb|center|Microduino-OLED]]
[[File:set_5.jpg|800px|thumb|center|Microduino-OLED]]
Step 5：Set the code;
[[File:set_6.jpg|800px|thumb|center|Microduino-OLED]]
Step 6：Use the code to replace the character.

Grammar：
*u8g.drawXBMP( X, Y, I, W, XXXX);
**X: horizontal coordinates, Y: longitudinal coordinate, I: long, W: wide, XXXX: Chinese character code name of the array.
