README

        # ovos-PHAL-plugin - Mark1

handles integration with the Mycroft Mark1 hardware

the firmware for mark1 arduino that controls the eyes and faceplate can be found [here](https://github.com/OpenVoiceOS/mycroft-mark1-firmware)

utits to interact with the faceplate pixel by pixel can be found in [ovos-mark1-utils](https://github.com/OpenVoiceOS/ovos-mark1-utils) 

# Serial Port Protocols

See the file [protocols.txt](./protocols.txt) for a description of commands that can be sent to the faceplate.

Commands can be sent from the command line on a Raspberry Pi, such as this:

```

$ echo "eyes.blink" > /dev/ttyAMA0

$ echo "eyes.color=16711680" > /dev/ttyAMA0

$ echo "mouth.text=I am angry!" > /dev/ttyAMA0

```

Which will blink the eyes, turn them red, then display the phrase on the faceplate.

# Graphics

The `mouth.icon=` command takes a custom format for it's black and white images.  You can use the [HTML editor](http://htmlpreview.github.io/?https://raw.githubusercontent.com/MycroftAI/enclosure-mark1/master/editor.html) to create the image strings that can be sent. 

# IO pins

When looking at the device from the back, pins are laid out as:

```
