I2C Display on EmonBase


Just wondered if anyone has had any luck attaching a i2c display to the emonbase?

I would only need Voltage and Amps displayed.


Hi Edd,

There’s a thread on the old forum called EmonLCD not GLCD. Unfortunately, the diagrams that were attached to the original posts have been lost.

Here’s a link to a sketch that uses a 4-line LC Display

Hey Bill

Thanks for your reply.

It seems like the script you have linked is for arduino. I would like to put a LCD onto the raspberry pi (emonbase) so i have a live read out of Voltage and amps on 3 phases, along with the more detailed view from the emoncms if the user wants to use that.


Yep. You did say emonBase. Sorry 'bout that. :sunglasses:

Is there any way to do this?

Google is your friend. :wink:

Here’s anrticle to give you an idea of what’s involved.


Thanks for this, i already have the i2c connected. I just need to know how i can get an output from the rpi to the lcd.


Any updates on this topic???
