GrovePi: Can I use a Digital or Analog Port to make an Extra I2C port?


#1

Dear Dexter,

For the same project as the adafruit motor shield project I’ve asked a question about earlier, I need to connect four humidity and temperature detectors to the GrovePi. The problem is that there are only 3 I2c ports. Is it possible to set an analog or digital port as an i2c port, or is there a different way of doing this? And if so, how do I do this?

Thanks,
Liam Joy

You can use an I2C hub like this or just stack another GrovePi which would give you more I2C ports.
