ovos-PHAL-plugin-mk1 0.1.4a5

A PHAL plugin for mycroft

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

utits to interact with the faceplate pixel by pixel can be found in ovos-mark1-utils

Serial Port Protocols

See the file 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 to create the image strings that can be sent.

IO pins

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

             -----------------------------------------------------------------------------------------------
