6 个评分

课程 2（共 6 门，Specialization Internet of Things）

Do you want to develop skills to prototype embedded products using state-of-the-art technologies? In this course you will build a hardware and software development environment to guide your journey through the Internet of Things specialization courses. We will use the DragonBoard™ 410c single board computer (SBC). This is the first in a series of courses where you will learn both the theory and get the hands-on development practice needed to prototype Internet of Things products. This course is suitable for a broad range of learners. This course is for you if: - You want to learn how to use learn how to use Linux for embedded purposes. - You want to pivot your career towards the design and development of Internet of Things enabled products - You are an entrepreneur, innovator or member of a DIY community Learning Goals: After completing this course, you will be able to: 1) Know where you can find resources and help in the 96Boards ecosystem. 2) Describe the DragonBoard™ 410c peripherals, I/O expansion capabilities, Compute (CPU and Graphics) capabilities, and Connectivity capabilities. 3) Understand how to navigate and make use of the Linux terminal. 4) Configure at least one integrated development environment (IDE) for developing software. 5) Make use of Git and GitHub for version control purposes. 6) Create and build projects that interface with sensors and actuators through GPIO and Arduino.

Introduction and Supplemental Materials

Welcome to the Internet of Things! Before diving into this course give us a chance to let you know what it is all about! We will walk you through a module by module outline that will give you highlights on the interesting aspects of the course. In this course, you will see a lot of new words and acronyms you might not be familiar with. If you feel comfortable with your knowledge of tech terminology, feel free to skip these lessons since they will not affect the overall integrity of the course. If you see something that you want to know a little more about, feel free to watch the video to gain insight on some basic concepts. We do expect you to know the majority of this material before going into the next module, we would recommend going through the lessons as a quick brush up.

Hello everyone and welcome to this section.

Here if you are a Windows user you need to do a few

tweaks to your USB driver so that your computer is able to use ADB.

Now if you're a Mac and Linux user, you can go ahead and skip to the next section.

>> Right, so, let's go ahead and get started.

The first thing that you need to do is go ahead and

boot up your Android Studio, as we have here.

We're going to go ahead and create a new Android Studio project, just so

we get in there, so I'm just gonna go ahead and click next all the way through.

Click finish.

The reason why we're starting in Android Studio project is so

we can gain access to the SDK manager.

Now, the SDK manager inside of Android Studio is essentially where you go to

update your SDK and various other Android tools such as downloading emulator

images or any other >> Different OS versions.

>> Yeah, also I think there's a wearables API in there and stuff like that.

So If you want to play around with android specific stuff,

SDK manager is definitely the way to go.

So currently we're just waiting for the project to open.

All right. So now if you notice,

way up at the top here, let me go ahead and maximize,

we have this little guy hiding inside a box.

Go ahead and click that.

As soon as it loads it should be

its own little pop-up window.

All right.

So right now it's fetching all the updates that we need,

now notice that we have a bunch of stuff checked off.

What I'm gonna do real quick is I'm just gonna ahead and

de-select everything, since I don't wanna install all this stuff.

These are your Android images that you would probably wanna install.

I'm gonna keep scrolling down.

And here is a support library that I'm gonna go ahead and

remove, as well as a google USB driver.

Now this is very important.

The USB driver here is the way you communicate

between your android device and the phone.

So you're going to go ahead and install this package, and then go ahead and

accept the license and click install.

So it should be a relatively fast install.

Now, we're also gonna take note of where our SDK is located, which is right here.

All right, so now I'm gonna go ahead and close this and we can go out and

close Android Studio at this moment in time.

Next, I wanna go to that directory, so what I'm gonna do.

So, I'm gonna open up my computer, go to C, programming, Android, and SDK.

All right, so now from here you wanna go inside of your extras directory,

go inside Google, and you're gonna go inside USB driver.

Now, here there's a file called android_winusb.inf.

I'm going to go ahead and open that,

and I'm just going to use a simple text editor such as Notepad ++.

As you see here,

there's a bunch of different headers with a bunch of information.

If we scroll down, you'll notice this Google.ntx86

has a bunch of gibberish-looking stuff, as well as this .NTamd64.

This is actually the information that your USB driver uses in

order to communicate via the inner device, so we just need to simply modify it.

Inside this text file I have the information needed for

the DragonBoard 410c.

So what I'm going to do is I'm gonna go ahead and click on this or drag this all.

>> And do note that we will provide the proper documentation for

this, so that you can reference it in case you're

unable to see all of the different things that we're copying over.

>> Yeah and by no means you should type this up you should definitely go

ahead and copy it.

So this first section you're going to go ahead and

find Google.NTX86 and I'm just gonna go ahead and add it right at the bottom here.

Next, I'm gonna go ahead and grab this section, and

I am failing today at copying text over.

Actually a really huge skill, not a lot of people have it.

>> Happens to the best of us.

>> So we're gonna go ahead and click Enter here.

And now we should have the necessary information needed to update our

USB driver.

Sometimes this works automatically, other times it doesn't, so let's go ahead and

just make sure it does.

Gonna go ahead and right click PC.

We're gonna go to Manage.

And essentially what we wanna do is we wanna go to our Device Manager.

Now, we won't see anything here right now, so

what we need to do is plug in a USB cable.

So what you want to do is make sure your Dragon Board is on and

you want to go ahead and connect the OTG port to the USB port.

>> And we're good.

>> All right. So we should have it connected.

I'm just going to do a quick scan and notice here that this popped up right now,

other devices and it says Android, Android, Android, which is perfect.

Just what we needed.

So what we want to do is we're going to go ahead and just click the first one and

say update driver software.

We're going to browse through the computer and

we're just going to go ahead and browse to where that folder is.

So if we go down to SDK down here,

go into extras, google, USB driver.

And that's perfect, that's exactly what we want.

Press okay, and press next.

Now sometimes you'll get this error

that either means that your driver is either updated or

that you might need to configure some settings in your operating system.

So at this moment in time, we are going to assume that our software is updated, and

if you run into a lot of issues you can go ahead and

reference them inside of our document.

So, as a result, we know how to update our USB drivers and

we hope to see you in the next section.
