Is it possible to use gobot libraries without all the gobot/robot initialization.

I'm wondering if it's possible to have a program like this

package main

import (
    "time"

    "github.com/hybridgroup/gobot/platforms/gpio"
    "github.com/hybridgroup/gobot/platforms/intel-iot/edison"
)

func main() {
    e := edison.NewEdisonAdaptor("edison")
    led := gpio.NewLedDriver(e, "led", "13")
    for {
        led.Toggle()
        time.Sleep(1)
    }
}

That could be part of another program. For instance if I want to read values from a sensor and send it to a database or another process. I think that I can achieve this by using a channel but the idea would be to have a simple way to get the ports/sensors data, something like the mraa library.

Is there a way to have such functionality on gobot?

Thanks

Try something like this, but with the Edison adaptor and let me know what happens.

You're basically on the right track, you just need to Connect() the adaptor.

Awesome! The connect() was the thing I needed. Now this code works

package main

import (
    "time"
    "github.com/hybridgroup/gobot/platforms/gpio"
    "github.com/hybridgroup/gobot/platforms/intel-iot/edison"
)

func main() {
    e := edison.NewEdisonAdaptor("edison")
    led := gpio.NewLedDriver(e, "led", "13")
    e.Connect()
    for {
        led.Toggle()
        time.Sleep(1000 * time.Millisecond)
    }
}

Thanks :)

One other small thing worth mentioning. You should also call Start() on the driver, to ensure that it is properly initialized:

package main

import (
    "time"
    "github.com/hybridgroup/gobot/platforms/gpio"
    "github.com/hybridgroup/gobot/platforms/intel-iot/edison"
)

func main() {
    e := edison.NewEdisonAdaptor("edison")
    led := gpio.NewLedDriver(e, "led", "13")
    e.Connect()
    led.Start()
    for {
        led.Toggle()
        time.Sleep(1000 * time.Millisecond)
    }
}

We should update the docs with this info, so people realize they can use Gobot as a set of Golang device libraries, not just use the entire framework.

[trevrosen]

@deadprogram if you want to make an issue and assign it to me w/ some details about what you'd like to see and what platforms to cover, I can take on that docs update.

Hi @trevrosen I just added hybridgroup/gobot-site#48 to discuss this.
