# CHIP
|
||
|
|
|
||
|
|
The [CHIP](http://www.getchip.com/) is a small, inexpensive ARM based single board computer, with many different IO interfaces available on the [pin headers](http://docs.getchip.com/#pin-headers).
|
||
|
|
|
||
|
|
For documentation about the CHIP platform click [here](http://docs.getchip.com/).
|
||
|
|
|
||
|
|
## How to Install
|
||
|
|
```
|
||
|
|
go get -d -u github.com/hybridgroup/gobot/... && go install github.com/hybridgroup/gobot/platforms/chip
|
||
|
|
```
|
||
|
|
|
||
|
|
## Cross compiling for the CHIP
|
||
|
|
If you're using Go version earlier than 1.5, you must first configure your Go environment for ARM linux cross compiling.
|
||
|
|
|
||
|
|
```bash
|
||
|
|
$ cd $GOROOT/src
|
||
|
|
$ GOOS=linux GOARCH=arm ./make.bash --no-clean
|
||
|
|
```
|
||
|
|
|
||
|
|
The above step is not required for Go >= 1.5
|
||
|
|
|
||
|
|
Then compile your Gobot program with
|
||
|
|
|
||
|
|
```bash
|
||
|
|
$ 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
|
||
|
|
|
||
|
|
```bash
|
||
|
|
$ scp chip_button root@192.168.1.xx:
|
||
|
|
$ ssh -t root@192.168.1.xx "./chip_button"
|
||
|
|
```
|
||
|
|
|
||
|
|
## How to Use
|
||
|
|
|
||
|
|
```go
|
||
|
|
package main
|
||
|
|
|
||
|
|
import (
|
||
|
|
"fmt"
|
||
|
|
|
||
|
|
"github.com/hybridgroup/gobot"
|
||
|
|
"github.com/hybridgroup/gobot/platforms/chip"
|
||
|
|
"github.com/hybridgroup/gobot/platforms/gpio"
|
||
|
|
)
|
||
|
|
|
||
|
|
func main() {
|
||
|
|
gbot := gobot.NewGobot()
|
||
|
|
|
||
|
|
chipAdaptor := chip.NewChipAdaptor("chip")
|
||
|
|
button := gpio.NewButtonDriver(chipAdaptor, "button", "U14_13")
|
||
|
|
|
||
|
|
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,
|
||
|
|
)
|
||
|
|
gbot.AddRobot(robot)
|
||
|
|
gbot.Start()
|
||
|
|
}
|
||
|
|
```
