Short Description
Node-RED and FRAM nodes to access ferroelectric memory of netPI RTE 3
Full Description

Node-RED + fram nodes

Made for netPI RTE 3, the Open Edge Connectivity Ecosystem with Real-Time Ethernet

Debian with Node-RED and fram nodes for ferroelectric random access memory access

The image provided hereunder deploys a container with installed Debian, Node-RED and fram nodes to communicate with the onboard ferroelectric random access memory.

Base of this image builds the latest version of debian:jessie with installed Internet of Things flow-based programming web-tool Node-RED and two extra nodes fram read and fram write providing access to netPI's 8kByte FRAM FM24CL64B.

Container prerequisites

Port mapping

To allow the access to the Node-RED programming over a web browser the container TCP port 1880 needs to be exposed to the host.

Host device

To grant access to the FRAM from inside the container the /dev/i2c-1 host device needs to be added to the container.

Getting started

STEP 1. Open netPI's landing page under https://<netpi's ip address>.

STEP 2. Click the Docker tile to open the Docker management user interface.

STEP 3. Enter the following parameters under Containers > Add Container

  • Image: hilschernetpi/netpi-nodered-fram

  • Port mapping: Host "1880" (any unused one) -> Container "1880"

  • Restart policy" : always

  • Runtime > Devices > add device: Host "/dev/i2c-1" -> Container "/dev/i2c-1"

STEP 4. Press the button Actions > Start container

Pulling the image from Docker Hub may take up to 5 minutes.


After starting the container open Node-RED in your browser with http://<netpi's ip address>:<mapped host port> e.g. Two extra nodes fram read and fram write in the nodes fram library palette provides you random access to netPI RTE 3's FRAM. Their info tabs in Node-RED explain how to use them.


  • hilscher/netPI-nodered-fram:latest - non-versioned latest development output of the master branch. Can run on any netPI RTE 3 system software version.
