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 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. Video
