==Objective==
This tutorial will teach how to move an image to the right dynamically on 16*16 lattice. Take an Chinese characters for example.

==Equipment==
*'''[[Microduino-Core]]'''
*'''[[Microduino-FT232R]]'''
*Other equipment
*USB cable
*LM-2256 16 *16 lattice

==Document==
LM-2256 Series 16 *16 matrix displays：'''[[File:.led_16_16.zip]]'''

==Feature==
*Small, the size is 40.46*40.46*5mm;
*Using 2mm round LED;
*LED lattice screen on a black background, very beautiful;

==Principle==
*Every 8 columns as a moving unit, moving 16 steps.
*In 0 ~ 8 moving step, the right part move to right, at the same time still need to put on the left side's data.
*In 8 ~ 16 moving step, put the left graphics code to the right directly and then move to right.

==Debug==
*Prepared Work
**Download test program: '''[[File:.led_16_16_move_right.zip]]'''
**Modulus software: '''[[File:PCtolCD.zip]]'''
*Step 1: Download the test program, unzip and open it;
*Step 2: Compile it and settle the board type to download;
*Step 3: Change the Chinese character or image
**Change font
Detailed information,please refer to: http://www.microduino.cc/wiki/index.php?title=%E7%AC%AC%E4%BA%8C%E8%AF%BE--Microduino_OLED%E4%BD%BF%E7%94%A8/zh

Note: modulus method changed to: determinant, Yang code, reverse.

**Change dynamic display timer
In loop() function, the second for() loop uses to control display timer for every image, large number with large timer.

==Grammar==
*"<<": left shift operator, From low to high
For example:
a=0x03;// binary:00000011
b=a<<3// binary:00011000
then b=0x18;
*"<<=": lefe shift operator, and assign the shift value to yourself.
For example:
a<<=0x03;
then a==0x18;

*">>": right shift operator, from high to low.
For example:
a=0x30;// binary:00110000
b=a>>3// binary:00000110
then b=0x06;

*"|": Bitwise or operator, as long as there is a data 1, then the result is 1, otherwise the result is 0.
 0 0 1 1 operand 1    
 0 1 0 1 operand 2  
 --------------
 0 1 1 1 result
*"&": Bitwise and operator, two data both are 1, then the result is 1, otherwise the result is 0.
 0 0 1 1 operand 1    
 0 1 0 1 operand 2  
 --------------
 0 0 0 1 result

==Result==
Through testing, the move speed of Chinese character is about half a second. Players can modify the display images and time according to his own interest.

==Pay attention issue==
*The difference between left shift and right shift;
*When change the font, need set the modulus format correctly.
