Lesson 32--Microduino 16*16 Lattice Character Transverse Move Display

Language:	English  • 中文

Objective This tutorial will teach how to move an image to the right dynamicly on 16*16 lattice. Take an Chinese characters for example. Equipment Microduino-Core Microduino-FT232R Other equipment USB calbe LM-2256 16 *16 lattice Document LM-2256 Series 16 *16 matrix displays：File:.led 16 16.zip Feature Smale, 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：Downlaod the test program, uncompress and open it； Step 2：Compile it and selte 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 dinamic 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. Video
