ovos-PHAL-plugin-dotstar 0.0.3a1

An OVOS PHAL plugin to control DotStar type LEDs

ovos-PHAL-plugin-dotstar

Compatible with

• Respeaker 2/4/6/8 i2c microphone HAT's
• Adafruit 2 mic VoiceBonnet

Usage

There are a few ways for this plugin to get enabled.

• Enable manually

Add this to your ~/.config/mycroft/mycroft.conf

{
    "PHAL": {
        "ovos-PHAL-plugin-dotstar": {
            "enabled": true
        }
    }
}

With this configuration, no other validation checks are made. It is assuming you have a compatible HAT installed.

• Automatically with ovos-i2csound

When ovos-i2csound is installed and running, it creates a file at /etc/OpenVoiceOS/i2c_platform with the HAT name it detected. This plugin then checks that file and if a compatible HAT is detected, the plugin is activated.

• Automatically with hardware detection

If the above two options don't work, the plugin tries to detect a compatible HAT using i2c-detect. If a compatible device address is found, the plugin will activate.

From this point, if you are using a ReSpeaker i2c microphone, your LED's should give you prompts of what is going on with your OVOS assistant.

Adafruit 2mic voicebonnet

The Adafruit voicebonnet can be used with this plugin, but it requires one more step of manual configuration. While the above detection options will properly enable the plugin, this HAT uses different GPIO pins for it's LED's, therefore cannot be easily distinguished from a ReSpeaker 2mic HAT.

Add the following to your ~/.config/mycroft/mycroft.conf file

{
    "PHAL": {
        "ovos-PHAL-plugin-dotstar": {
            "dotstar_hat": "ADAFRUIT2MIC"
        }
    }
}

And restart OVOS

Your LED's on your Adafruit voicebonnet will now show the same prompts as the ReSpeaker devices.

Custom Configuration

Colors and animations can be configured in ~/.config/mycroft/mycroft.conf

            "listen_animation": "breath",

        }
    }
