7.13 8x8 LED Matrix
With low-voltage scanning, LED dot-matrix displays have advantages such as power saving, long service life,
low cost, high brightness, wide angle of view, long visual range, being waterproof… LED dot-matrix displays can
meet the needs of different applications and thus have a broad development prospect.
The 8*8 dot-matrix is made up of sixty-four LEDs, and each LED is placed at the cross point of a row and a
column. When the electrical level of a certain row is 1 and the electrical level of a certain column is 0, the
corresponding LED will light up. If you want to light the LED on the first dot, you should set pin 9 to high level
and pin 13 to low level. If you want to light LEDs on the first row, you should set pin 9 to high level and pins
13, 3, 4, 10, 6, 11, 15 and 16 to low level. If you want to light the LEDs on the first column, set pin 13 to low
level and pins 9, 14, 8, 12, 1, 7, 2 and 5 to high level.
