Description
8×8 matrix
- In a 8×8 matrix,the LEDs would need 64 I/O pins, one for each LED pixel. By wiring all the anodes together in rows (R1 through R8), and cathodes in columns (C1 through C8), the required number of I/O pins is reduced to 16.
- Each LED is addressed by its row and column number.Characters can be displayed by fast scanning of either rows or columns.
- To display a character,the row and column pins should be pulled low and high according to that character.
