Mark 1 LED Matrices/LED Matrix

Hi all,

Best examples of programming the LED Matrix/Matrices on the face of the Mark 1?

I would like to show simple images vs. text/numbers.

Thanks,

Greg

Hi @gov - some alpha documentation on this here:
https://github.com/MycroftAI/docs-rewrite/blob/70a72facd4a72f9951d84b8eb0657c925fc071fe/_drafts/Skill-Display-Control.md

Feedback warmly welcomed.

Ok, here we go . . . some observations with my Mark 1 Matrix display so far:

  1. In order to print text to the Matrix, I needed to deactivate the mouth as seen from this
    code segment from skill-ip:

     def handle_intent(self, message):
         self.speak("Here are my available I.P. addresses.")
         self.enclosure.deactivate_mouth_events()
          . . .       
          
                     self.enclosure.mouth_text(address)
                     time.sleep((self.LETTERS_PER_SCREEN + len(address)) *
                                self.SEC_PER_LETTER)
         self.enclosure.activate_mouth_events()
         self.speak("Those are all my I.P. addresses.")
        ...

  2. I am not able to get an “image” on the matrix, looking at my mycroft-skill.log file:

     2017-11-26 16:53:31,912 - mycroft.skills.core - ERROR - An error occurred while processing a request in SmartEyeSkill
 Traceback (most recent call last):

     self.enclosure.mouth_display(img_code="aIAAAAMPHIFIHLMMMMELGIGIMPA", refresh=False)
 AttributeError: EnclosureAPI instance has no attribute 'mouth_display'

hopefully I’ve made some inane spelling error or something, but so far no go on this . . .anyone see anything here?

  1. I have successfully attached and used the rasp pi camera to the Mark 1, but in order to get the clarifai api to work, I need to uninstall PIL, which is used to generate images from PNG files by the Mark 1, so I think I “broke” some skills using this library :frowning:

@gov check out the datetime skill https://github.com/MycroftAI/skill-date-time. It has examples of how to program to the matrix.
