目录ObjectiveThis experiment will introduce how to use the Microduino I/O port to control 5*7 lattice and without drive chip. Equipment
Schematic
Common cathode:All the cathode of LED connect together, and use high level to light the LED. Common anode:All the anode of LED connect together, and use low level to light the LED. DebugMeasure lattice pinIf you don't have hte lattice pin diagram, measure it by yourself. Detailed step, please refer to 8*8 lattice. http://v.youku.com/v_show/id_XNjg0NTk4Nzk2.html Set up circuit
Program
Step 1:Download test program, and open it; Step 2:Select the board type and download directly, after download a picture will be shown on lattice
Change the fontDetailed 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: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. Change the font code in data[], download directly and then display the new image on lattice. ResultBy testing, lattice can display an image and each LED's brightness is uniform, very beautiful. Video |
