Detailed step, please refer to 8*8 lattice.<br /> <br /> http://v.youku.com/v_show/id_XNjg0NTk4Nzk2.html<br /> <br /> ===Set up circuit===<br /> *Connect the column pin to D2-D6 and row pin to D7-D13；<br /> {|class=&quot;wikitable&quot;<br /> |-<br /> |D2||D3||D4||D5||D6<br /> |-<br /> |COL1||COL2||COL3||COL4||COL5<br /> |-<br /> |D7||D8||D9||D10||D11||D12||D13<br /> |-<br /> |ROW1||ROW2||ROW3||ROW4||ROW5||ROW6||ROW7<br /> |}<br /> [[File:led_5_7_line.jpg|600px|center|thumb]]<br /> <br /> ===Program===<br /> *Prepared Work：<br /> **Download test protram：'''[[File:.led_5_7_static.zip]]'''<br /> **Modulus software：'''[[File:PCtolCD.zip]]'''<br /> Step 1：Download test program, and open it；<br /> Step 2：Select the board type and download directly, after download a picture will be shown on lattice<br /> *Note:<br /> **duan[] array use to store column data, data[] array use to store row data;<br /> **If need change the picture, only need change the data in array data[], five data represent a picture;<br /> **leddisplay() function configures the lattice row pin. Function ledduan() uses to configure lattice column pin;<br /> **Use the right shift operation &quot;&gt;&gt;&quot; to move out the data and output to I/O port, then light the LED.<br /> **This experiment uses the common cathode lattice, if use the common anode lattice with the same pin defination, need reverse the array data. For example, change the &quot;data[i]&quot; to &quot;~data[i]&quot;. If the pin defination is different, need change the pin's configuration in function leddisplay() and ledduan().<br /> <br /> ==Change the font==<br /> 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<br /> Note：Need to replace modulus with image model, and new a 5*7 image. Draw a image, then the modulus way changed to: Yin, column type, reverse.<br /> <br /> Change the font code in data[], download directly and then display the new image on lattice.<br /> <br /> ==Result==<br /> By testing, lattice can display an image and each LED's brightness is uniform, very beautiful.<br /> [[File:led_5_7_static_Result.jpg|600px|center|thumb]]<br /> <br /> ==Video==<br /> <br /> |}</div>
