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

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