In this tutorial we will learn how to use 8\u00d78 LED Matrix to display images, scrolling text, and few more transitions with VEGA ARIES Boards. These displays are so popular that almost all modern outdoor LED displays use them to display characters, symbols, and images.<\/p>\n\n\n\n

MAX7219 Dot Led Matrix Module<\/h2>\n\n\n\n

An 8\u00d78 dot matrix display typically has 16 pins, 8 for each row and 8 for each column. All rows and columns are wired together in order to reduce the number of pins.This technique of controlling a large number of LEDs with fewer pins is referred to as Multiplexing<\/strong>. While using this multiplexing technique you have to refresh the display all the time to keep the image stable.  The MAX7219 Chip, which handles all of the control and refresh part. We just need to send serial commands through the 4-pin SPI interface, and it will take care of the rest.<\/p>\n\n\n\n

ARIES v3.0<\/h2>\n\n\n\n

The ARIES v3.0 is a fully indigenous and a \u201cMade in India\u201d product to get started with basic microprocessor programming and embedded systems. This board is built upon a RISC-V ISA compliant VEGA Processor with easy-to-use hardware and software. For more details about ARIES v3.0 boards please refer to the ARIES development boards and Ecosystem<\/a>.<\/p>\n\n\n\n
