Driving a 7 segment display

Tue Aug 18, 2015 8:35 pm


I have a few of these, but was wondering if there is a way to run one, or a series of these, without using 6 GPIO each.


I found this, but has anyone found a ready-made module for numbers?

You mean like this: https://www.adafruit.com/products/879

i2c controller would do it with 2 gpio and would be easy to code, And this is ready made.

Use a shift register! The 74HC595 is perfect for this. Image

Instead of arduino use vocore GPIOs :P :geek:
Hey I'm new and just getting started with vocore :)

Return to VoCore & VoCore+Dock
