RGB #6

Testing RGB....

Firstly the node always initiates with error message underneath it. "Missing connection" Then we managed to send "Hello world" - but there is no documentation we can see as to how to clear the screen, change the backlight colour or anything - just send text to a row and column. Are we missing something?

scargill:

That particular node seems to only support the one REST call and this repository has not been updated in a while. I have been editing some of the code in my fork - added a LED Bar node and fixed the config node to work with the new servers. You could look at the flows here (https://seeed.cc/WIO-Link-HTTP-Requests-from-Node-RED-p-1718.html) which shows how to use the HTTP nodes to communicate. I will try to look at the RGB node soon to add functionality to it (I'm using these as a way to learn and practice JS and Node). When I get my code to where I want it, I will do a pull request back here. How are you powering your display since the Wio only puts out 3.3v and the display requires 5v?
