Multiple I2C 4-Digit 7-Segment Displays??

Post by mattc1234 »

Hi,

My project is going to be using 10 separate 4-Digit 7-Segment Displays, run off of an Arduino Mega. I'm hoping to use I2C to connect this since it'd take a lot of pins otherwise. I would assume each one of the displays has the same I2C address. Is there an easy work-around for this? To have all 10 of the same thing hooked up and control them all? What issues would I have if I tried to set them all up at once? The link to the item I'm looking at is:

Thanks so much!
Matt

The 4-bit address on each breakout allows for 8 unique addresses. In this project, some tricks were used to extend the effective addressing capability: http://learn.adafruit.com/delorean-time ... t-trickery
