4 LED matrices off one backpack?
Hello, I am beginning my first raspi project, which will be 4 LED scoreboards, all displaying the same pair of numbers (the score for player 1 and the score for player 2, repeated 4 times in different locations)
I'm thinking I could use the 8x8 backpack matrices with the i2c output. The scores won't go beyond 10, so I will be able to display all the numbers I need with the matrix, which will have the old scool mini lightbulb look I'm going for (rather than 7 segment).
1. If I go this route, Can I just connect all the similar matrix pins (for the player one displays, for example) in parallel? I have a feeling I need to make some adjustments.
2. Is there a more efficient solution than using all these backpacks? Seems to me I would be overdoing it since I really just need 4 duplicate "dumb" displays all using the same logic. Maybe I could wire 4 matrices off of one backpack?
Thanks all! Love the site. Learning a lot here.
