So I know the panels work and everything is good there. However what I am building is a low rez pixel digital art frame for the wall which I want to put pictures and animated images on it as an art piece. I found a project walk through that looks exactly what I need (ability to create a web interface that I can connect to and load stuff up on it). However this is where I get stuck.
The guide I am trying to follow is this one: https://learn.adafruit.com/raspberry-pi ... p/overview
(Note I am a complete noob to all this, great at following instructions but navigating outside of those instructions becomes a challenge).
I've gotten all the way through without seemingly any errors to the point where I need to run some demos on it. I run the command:
Code: Select all
$ cd rpi-rgb-led-matrix/examples-api-use
$ sudo ./demo -D -m 0 --led-no-hardware-pulse --led-gpio-mapping=adafruit-hat
One thing to note, when I went through the first tutorial it had me setup some configuration to tell it how the screens were configured and in what order. This second one didn't seem to do that at all.
Another issue further along (I kept going seeing if I could at least finish up and get the web service up) is that I get to a point where it asks to just some commands:
Code: Select all
$ java -jar payara-micro-prerelease-2016-11-24.jar --deploy rpi-rgb-led-matrix-webapp-0.0.1-SNAPSHOT.war
Any help greatly appreciated! Thank you!
