blinkt_go
This library is work-in-progress and makes use of WiringPi and the Golang
rpilibrary.
Instructions:
Install Go
If you don't have Go on the Pi, download it from: https://golang.org/dl/ and pick the armv6l edition.
sudo tar -xvf go1.7.4.linux-armv6l.tar.gz -C /usr/local/
export GOPATH=$HOME/go
Install WiringPi
# sudo apt-get install -qy wiringpi
Install and build blinkt! library
# export GOPATH=$HOME/go/
# mkdir -p $GOPATH/src/github.com/alexellis/
# cd $GOPATH/src/github.com/alexellis/
# git clone https://github.com/alexellis/blinkt_go && cd blinkt_go
# go get
# go build
# sudo ./blinkt_go
sysfs implementation and Docker Swarm
Docker Swarm cannot run the main version of this library because WiringPi needs elevated privileges.
To use this library with Docker Swarm please use the version of Blinkt in the sysfs package.
For more information on sysfs see: http://elinux.org/RPi_GPIO_Code_Samples#sysfs

Functions ¶
Types ¶
type Blinkt ¶
type Blinkt struct {
// contains filtered or unexported fields
}
Blinkt use the NewBlinkt function to initialize the pixels property.
func NewBlinkt ¶
NewBlinkt creates a Blinkt to interact with. You must call "Setup()" immediately afterwards.
func (*Blinkt) Clear ¶
func (bl *Blinkt) Clear()
Clear sets all the pixels to off, you still have to call Show.
func (*Blinkt) SetAll ¶
SetAll sets all pixels to specified r, g, b colour. Show must be called to update the LEDs.
func (*Blinkt) SetBrightness ¶
SetBrightness sets the brightness of all pixels. Brightness supplied should be between: 0.0 to 1.0
func (*Blinkt) SetClearOnExit ¶
SetClearOnExit turns all pixels off on Control + C / os.Interrupt signal.
func (*Blinkt) SetPixel ¶
SetPixel sets an individual pixel to specified r, g, b colour. Show must be called to update the LEDs.
func (*Blinkt) SetPixelBrightness ¶
SetPixelBrightness sets the brightness of pixel p. Brightness supplied should be between: 0.0 to 1.0
