README

C.H.I.P.

The C.H.I.P. is a small, inexpensive ARM based single board computer, with many different IO interfaces available on the pin headers.

We recommend updating to the latest Debian OS when using the C.H.I.P., however Gobot should also support older versions of the OS, should your application require this.

For documentation about the C.H.I.P. platform click here.

How to Install

go get -d -u gobot.io/x/gobot/... && go install gobot.io/x/gobot/platforms/chip

How to Use

The pin numbering used by your Gobot program should match the way your board is labeled right on the board itself.

package main

import (
    "fmt"

    "gobot.io/x/gobot"
    "gobot.io/x/gobot/drivers/gpio"
    "gobot.io/x/gobot/platforms/chip"
)

func main() {
    chipAdaptor := chip.NewAdaptor()
    button := gpio.NewButtonDriver(chipAdaptor, "XIO-P0")

    work := func() {
        gobot.On(button.Event("push"), func(data interface{}) {
            fmt.Println("button pressed")
        })

        gobot.On(button.Event("release"), func(data interface{}) {
            fmt.Println("button released")
        })
    }

    robot := gobot.NewRobot("buttonBot",
        []gobot.Connection{chipAdaptor},
        []gobot.Device{button},
        work,
    )

    robot.Start()
}

How to Connect

Compiling

Compile your Gobot program like this:

$ GOARM=7 GOARCH=arm GOOS=linux go build examples/chip_button.go

Then you can simply upload your program to the CHIP and execute it with

$ scp chip_button root@192.168.1.xx:
$ ssh -t root@192.168.1.xx "./chip_button"

Types

type Adaptor added in v1.0.0

type Adaptor struct {
	// contains filtered or unexported fields
}

Adaptor represents a Gobot Adaptor for a C.H.I.P.

func NewAdaptor added in v1.0.0

func NewAdaptor() *Adaptor

NewAdaptor creates a C.H.I.P. Adaptor

func (*Adaptor) Connect added in v1.0.0

func (c *Adaptor) Connect() (err error)

Connect initializes the board

func (*Adaptor) DigitalRead added in v1.0.0

func (c *Adaptor) DigitalRead(pin string) (val int, err error)

DigitalRead reads digital value from the specified pin. Valids pins are the XIO-P0 through XIO-P7 pins from the extender (pins 13-20 on header 14), as well as the SoC pins aka all the other pins.

func (*Adaptor) DigitalWrite added in v1.0.0

func (c *Adaptor) DigitalWrite(pin string, val byte) (err error)

DigitalWrite writes digital value to the specified pin. Valids pins are the XIO-P0 through XIO-P7 pins from the extender (pins 13-20 on header 14), as well as the SoC pins aka all the other pins.

func (*Adaptor) Finalize added in v1.0.0

func (c *Adaptor) Finalize() (err error)

Finalize closes connection to board and pins

func (*Adaptor) GetConnection added in v1.2.0

func (c *Adaptor) GetConnection(address int, bus int) (connection i2c.Connection, err error)

GetConnection returns a connection to a device on a specified bus. Valid bus number is [0..2] which corresponds to /dev/i2c-0 through /dev/i2c-2.

func (*Adaptor) GetDefaultBus added in v1.2.0

func (c *Adaptor) GetDefaultBus() int

GetDefaultBus returns the default i2c bus for this platform

func (*Adaptor) Name added in v1.0.0

func (c *Adaptor) Name() string

Name returns the name of the Adaptor

func (*Adaptor) SetName added in v1.0.0

func (c *Adaptor) SetName(n string)

SetName sets the name of the Adaptor
