Description¶
Edge Impulse is the leading development platform for machine learning on edge devices. Their portal allows you to train machine learning models and deploy those models on stand alone embedded devices.
The Virtual Breadboard EdgeImpulse icon can be used to aquire data from virtual or real data sources ( via EDGEY interface) and upload to a specific EdgeImpulse project via their Injest Service.
On the Record pin a rising-edge high data capture starts. Every rising-edge on the Sample pin records a sample from all Axis pins is recorded with the Interval timestep. If Sample pins is not wired then every simulated Interval milliseconds a sample is recorded from all Axis pins. On the falling-edge of the Record pin the recorded data will be submitted using theHMAC and API KEY to either the training, testing or anomoloy service specified by the Injest property. The data is submitted using the active Data Label pin.

Data Labels¶
A data label marks a collection of data as representing a certain type of event or feature. Each data set has a label when submitted. When attaching labels a pin for each label is dynamically generated. To submit data for a specific label the pin should be active HIGH during the sampling period.
Example: Data Labels : VERTICAL,HORIZONTAL,CIRCLE
Axis¶
An axis is a data source which is a sampled as a voltage nominally between 0 and 1. When attaching axis’ a pin for each Axis is dynamically generated. The pin should be wired to a VBB data source. When a sample is taken data is captured from the VBB data source.
Example: Axis : X,Y
Units¶
A unit marks up an axis with a specific unit describing what the data represents

Interval¶
The interval(ms) is the number of milliseconds between samples reported in the submitted data. In synchronous mode the interval is added for each sampling event. In asynchrounous mode (Sample pin is not wired) every interval milliseconds simulated time a sample is recorded.
Note: simulated time is usually real-time but for high frequency circuits this is not always true
API Key¶
Each Edge Impulse project has a unique API key ei_.. which can be found in the Dashboard/Keys panel. This is required to submit the data to the correct project.
HMAC Key¶
Each Edge Impulse project has a unique HMAC key which can be found in the Dashboard/Keys panel. This is required to secure the submitted data.
Submissions¶
Edge Impulse models have a minimal data set requirement. To submit the same data multiple times select submission count more than one. Each data set is rotated by 1 on each submission so that the data sets are not all identical.
Ingest¶
The Edge Impulse Ingest endpoint support 3 destination locations. This is where the data set will be directed when submitted
