led matrix driver
Hi guys,
i need to interface the attached ST7066Uv22 with a led matrix instead of a common LCD segment.
Can I drive a led matrix with this IC with a trasistor that interface the low power of the IC with the led?
Le led matrix is organized in row and coloumn. Can i drive them as page 40 of the datasheet using the transistor? How i connect the transistor to the led with the necessary 5V supply?
Hoping i'm clear.
Thank You.
Luigi.
