This is just a client for the Pixoo 64 sign written in Ruby.
Draw some stuff and then display it as an animated image:
include Pixoo::Utils
images = [7, 17, 29].map { |m|
img = Pixoo::ImageBuffer.new 64, speed: 500
64.times do |x|
64.times do |y|
if ((x | y) % m).zero?
img.set_pixel x, y, *(rainbow_color(x))
end
end
end
img
}
dev = Pixoo::Client.find_all.first
dev.send_animation images
sleep 1
# add some text
dev.send_text "Hello", x: 0, y: 0, id: 1
dev.send_text "World", x: 0, y: 40, id: 2, font: 6Read a PNG and display it:
img = Pixoo::ImageBuffer.from_png ARGV[0]
dev = Pixoo::Client.find_all.first
dev.send_animation [img]This thing supports reading values from a remote server. I have a server that collects PM2.5 / CO2 sensors I have in the house. On the server, I have a webrick server that response to requests for sensor info. For example to get the PM2.5 data from my office, I can do this:
$ curl 'http://tender.home:9292/reading?floor=main&room=office&measurement=pm2.5'
{"DispData":"25"}
The response is important because this display will parse the response and display it on the sign. I've configured the sign as follows:
dev = Pixoo::Client.find_all.first
label = dev.new_display_item(id: 1,
type: Pixoo::DisplayItem::TEXT_MESSAGE,
x: 0,
y: 0,
dir: 0,
font: 18,
width: 64,
height: 5,
string: "PM2-5:",
speed: 10,
color: "#FF0000",
align: 1)
value = dev.new_display_item(id: 2,
type: Pixoo::DisplayItem::NET_TEXT_MESSAGE,
x: 23,
y: 0,
dir: 0,
font: 18,
width: 64,
height: 5,
string: "http://tender.home:9292/reading?floor=main&room=office&measurement=pm2.5",
speed: 10,
color: "#FFFFFF",
align: 1)The sign will automatically fetch data from my server and update the display.
