I2C2 now working on pico?

I2C should work with many devices on a bus, but there are sometimes some issues:

• Each device has to have a different address (so 2 of the same device isn't usually possible)
  
• A lot of the boards you get with I2C devices on have pullup resistors pre-installed. If you put too many of them together you're going to end up with too much pullup resistance.
  
  

Hope that helps!
