EEA walkthrough

Trying to to test the EEA on a raspberry Pi using the walkthrough by I’m having a hard time finding what I should change in the step1.py to make it work with pywasm3 since the walkthrough is using wasmer.

Hey Lars,

You can find a full Python example using pywasm3 here:

github.com

Losant/eea-examples/blob/main/python/eea_runtime_pywasm3.py

#
# This module contains an example pywasm3 runtime.
# https://github.com/wasm3/pywasm3
#

import json
import os
import threading
import time

import wasm3

import eea_api
import eea_utils
import eea_registered_functions


# Initialize an instance of the EEA.
def init(device_id, eea_queue, mqtt_queue,
  persisted_bundle_path="./bundle-pywasm3.wasm",

The walkthrough is intended to communicate the main concepts of the EEA using one specific runtime.

Using the EEA, for any practical purposes, will require a deep understanding of your language, runtime, and overall WebAssembly concepts. So while we can’t provide step-by-step instructions for every combo of language/runtime, all runtimes share similar concepts and conventions and it’s up to the application developer to write the native code that loads and interacts with the EEA WASM module.

Hey Lars,

We’ve also published a Raspberry Pi / Vibration Analysis how-to guide here:
