SkyLight

Project Skylight is a collection of nodes that you can easily configure to control electronic fursuits

Installation

./install_dependencies.sh
./build_and_install.sh

Running nodes

sudo skylight_gpio - runs the gpio node in the terminal

sudo systemctl start skylight_gpio - runs the node in the background

sudo systemctl enable skylight_gpio - runs the node on startup

Nodes!

skylight_cli

A command line tool used to publish void, string and float commands to any channel

Options:
-h,--help                   Print this help message and exit
-c,--channel TEXT REQUIRED  The channel to broadcast on, sends a simple_void message if no other arguments are used
-s,--string TEXT            send a simple_string message
-f,--float FLOAT            send a simple_float message

skylight_sound

The sound node creates a sound object for each device listed in skylight_sound.toml

Default device names are internal and external

Subscribes to

Topic	Type	Example
/sound/[device name]/say	string	hello there
/sound/[device name]/play	string	~/example.wav
/sound/[device name]/volume	float	0.4

---

skylight_speech

Subscribes to

Topic	Message Type
/speech/start	void
/speech/stop	void

Publishes to

Topic	Message Type	Example
/speech/command	string	start rainbow

---

skylight_gpio

Subscribes to

Topic	Message Type
/gpio/update	void
/gpio/led_buffer	pixel_buffer

Publishes to

Topic	Message Type
/gpio/button_[pin]/[up/down]	void

---

skylight_effect_driver

Subscribes to

Topic	Message Type
/effect_driver/effects/test/start	void

Publishes to

Topic	Message Type
/effect_driver/buffer	void
/effect_driver/update	void

---

skylight_effect_driver_and_gpio

This node combines the effect driver and gpio, reducing the latency due to large buffers being sent over the network. It has the same subs and pubs as their individual nodes.

Configuring nodes

sudo nano /usr/local/etc/skylight_gpio.toml

#config for the gpio system
spi_speed = 10000000 #10mhz for the spi update
spi_device = 0
gpio_ports = [17, 27]
gpio_debounce = 100 #microseconds

All node configuration can be found in /usr/local/etc/

Configuring node communication

sudo nano /usr/local/etc/topic_config.toml

[routing]

"/effect_driver/led_buffer" = "/gpio/led_buffer"
"/effect_driver/update" = "/gpio/update"

"/gpio/button_27/down" = "/effect_driver/test"

Rebuilding and re-installing a single node

note - If you are building the modules individually and haven't run build_and_install.sh, please copy src/config/topic_config.toml to /usr/local/etc manually

cd src/nodes/gpio
mkdir build
cd build
cmake ..
make
sudo make install
