Do you have any example code to help me get started?

Bläckfisk is available for basic free support via support@blackfisk.com and we always have paid support options available.

When getting started with Bläckfisk Chrome App, its always best to start with code block below.

<script>window.addEventListener('message', (event) => {
console.log('received message', event)
})
</script>

This basic script will output all activity from the Bläckfisk Chrome App system. From this point, just tie into any event you want control over or interface with to better support your app.

How do I get USB Scale Weight?

Using the same logic as above with the command window.postMessage send a payload. The USB Scale expects an object to contain 2 keys. The type & the last known weight. Zero if you don't have a weight.

{type: 'scale', weight: 0}

And the scale if connected will respond with a valid weight via the addEventListener response.

Do you have support for Bluetooth or WiFi devices?
