2009/11/7· I matrix the data using one byte to hold 7bits for the vertical 7 pixels on the 5x7 displays. Then scrolling left is performed by moving all the bytes left one space. So if you have a 5 digit 5x7 display it needs 25 bytes to hold the display data. I "define letters" using a lookup table, and write the letter to a "scratchpad" of 5 bytes which is

LED Dot Matrix Display : 5 Steps - Instructables

Dot matrix units typically come in either a 5x7 or 8x8 matrix of LEDs. The LEDs are wired in the matrix such that either the anode or hode of each LED is common in each row. In other words, in a common anode LED dot matrix unit, each row of LEDs would have all of their anodes in that row wired together.
