Lesson 25--Microduino 5*7 Lattice Static Display
|Language:||English • 中文|
This experiment will introduce how to use the Microduino I/O port to control 5*7 lattice and without drive chip.
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.
Measure lattice pin
If you don't have the lattice pin diagram, measure it by yourself. Detailed step, please refer to 8*8 lattice.
Set up circuit
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 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 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.
By testing, lattice can display an image and each LED's brightness is uniform, very beautiful.
