Foorious For Mac

Here is a 'generic' step-by-step to getting an AVR development platform going on your computer using the free AVR toolchain (avr-gcc, avr-libc and avrdude) Pretty much every project uses this toolset so its a good way to get going

The following two methods both place all of the files in the /usr/local/bin directory in the hard driver. Unfortunately that directory is not in the default path. That means that when you type avrdude into the terminal it cant figure out where to look. In this prep-step you'll change the profile of your Terminal to add /usr/local/bin to the path.

Find the Terminal program, you'll be using this to do most of this stuff. Its in the Applications/Utilities folder

In the new Terminal window, type in echo $SHELL and press return

Fast and Foorious; - Scooby-Doo's museum; and - Tom and Jerry's Swiss Cheese Twist. Although the last two broke down and the queues were delayed (and.

If the output is /bin/bash then type the following command:
echo 'PATH=$PATH:/usr/local/bin' >> ~/.bash_profile
all on one line. Press return.

If the output is /bin/csh or /bin/tcsh then type the following command:
echo 'set path = ($path /usr/local/bin)' >> ~/.cshrc
all on one line. Press return.

Close any Terminal windows and open up a new one. This makes sure the .bash_profile or .cshrc is reloaded. Now type in echo $PATH (for bash) or echo $path (for t/csh) you should get something like the following:

The important thing is that at the end of the line is /usr/local/bin

This is the suggested method

Download the ready to go nice package from ObDev, I havent tried it but a friendly email'er said its great.

This isnt suggested, and is an older method, but we leave the documentation here in case its handy

You will need make which is included in XCode, as OSX-AVR doesn't come with it (ugh)

Step 1. Download and install the mac developer tools (XCode).

You need to have make installed, but it doesn't come with the OSXAVR package. You can try installing it with fink, which will require a lot less space but the following is guaranteed. If you want to have the latest avr-gcc you may also have to do it the 'old way' which guarantees the most recent tools will be installed.

To install XCode you will need the official packages. These are available on your Mac OS X Install CD, or from apple at: apple developer tools. The file is about 900MB so unless you have a fast connection I strongly encourage grabbing it off of the Install CDs that came with your Mac (you do still have those, right?) Basically we need the native Mac OS X compiler tools so that we can generate the AVR compiler tools.

There's finally a good/fast way of installing all these tools under Mac OS X PPC or i386! First, download the OSX-AVR packge for PPC (older macs) or i386 (Intel macs, latest ones) from sourceforge.

Run the OSX-AVR.mpkg

You're done!

(Images of installation and process are forthcoming but its rather easy so go ahead and try it anyways)

Don't forget you have to install XCode as make doesn't come with this package.

Can't get it working? Dont worry, help is available in the forums!

This is the advanced method, for when you need bleeding-edge development and hackability. Not suggested

The following steps are essentially the same for MacOS X or Linux, BSD or any other unixy OS. This is the 'old style' of installing avr-gcc, its longer and more tedious but you are guaranteed to have the latest version.

(Note that this doesn't seem to work on Intel Macs for unknown reasons, we're investigating..)

Leah Buchley has an excellent tutorial, and you should follow it. I've reduplicated it here in case the site goes down. (also with a few minor 'improvements' and images

Step 2. Download & install binutils (an essential utility for the C compiler)

Download the current release of binutils from : http://www.gnu.org/software/binutils/ (you can also go straight to the download site here) For these examples, we'll be using binutils-2.17.tar.gz but you should use whatever is most recent. Save it into your home directory, not the desktop.

Decompress the downloaded file and double click on it to decompress it (or use Stuffit Expander, in the Applications folder). You should now have a folder called binutils-2.17 which you should drag into your Home directory

Open up a Terminal window and navigate to the binutils directory. Type: cd binutils-2.17 <return> (or whatever you downloaded) theb type in ls to verify everythings there

Configure binutils for AVR. type: ./configure --target=avr <return>
this will start a long process that will spit out a lot of text.

Once its done, compile binutils. type: make <return>
this will start an even longer compilation process

This app includes all that you need to know to speak, write and understand English language completely.Classes feature grammar, frequently used phrases, when and where to use small letters, capital letters, form sentences and many more. It also includes alarm reminders and progress chart.Contents1. Easy and effective 50 days classes which will transfer to an English expert. Vowels and Consonants3. Meditation videos in tamil free download.

Once that's done, install binutils. type: sudo make install
You will be prompted to enter your password. Only administrators can install software thats why the password is necessary.

Step 3. Download & install gcc (the C compiler)
First, download the current release of gcc from: http://gcc.gnu.org/mirrors.html currently thats gcc 4.2.0

Decompress the downloaded file and put the decompressed folder in your home directory. Open up a new Terminal window in your home directory, type cd gcc-4.2.0 and then ls to verify its all in there.

Next, c reate another directory to install gcc into.
type: cd . <return> to go back into the home directory, then
type: mkdir avrgcc-4.2<return> (substituting your gcc version for the 4.2)
Navigate to the folder you created.
type: cd avrgcc-4.2 <return> (or whatever you named your folder)
Configure gcc for AVR.
Type: ./gcc-4.2.0/configure --target=avr --enable-languages=c --disable-libssp
(substituting the name of the folder you decompressed for the gcc-4.2.0)
**thanks to Seth Raphael for the --disable-libssp tip

Once the configuration is done, compile gcc.
type: make CC='cc --no-cpp-precomp' <return>

This will take a long time so go have a sandwich

When its done and you've washed your plate and silverware, install gcc. type: sudo make install<return>
and enter your password when prompted

Step 4. Download and install avr-libc (an essential C library for AVR chips)

Download the current release of avr-libc from : http://savannah.nongnu.org/projects/avr-libc/

Decompress the downloaded file and put the decompressed folder in your home directory

In a new Terminal window, navigagte to the avr-libc directory. from your home directory
type: cd avr-libc-1.4.6 <return> (or whatever you downloaded)

Configure avr-libc. type: ./configure --host=avr <return>

Compile avr-libc. type: make

Install avr-libc. type: sudo make install

Step 5. Download and install avrdude (the software that loads programs from your machine onto the chips)

Download the current release of avrdude from : http://download.savannah.gnu.org/releases/avrdude/

Decompress the downloaded file and put the decompressed folder in your home directory

In a Terminal window, navigate to the avrdude directory. From your home directory type: cd avrdude-5.2 (or whatever you downloaded)
Configure avrdude. type: ./configure
Compile avrdude. type: make
Install avrdude. type: sudo make install

Yay all the software is installed!

Today’s computer shopper has a choice of two great software platform standards in Windows and Mac, but lines have blurred between the types of hardware, which generally share Intel® CPUs.

Which Platform Is Right for You?

Consider if you like the Mac hardware and software aesthetic or would prefer the roll-your-own configurations that come with PCs.
Decide whether you will use touch and voice input capabilities.
Determine what software you’ll use and where you’ll keep it—on your computer or in the cloud.
Consider whether your future needs might require upgrades and additions to the computer.

In computing circles, “PC vs. Mac” has long been a topic of debate—advocates on both sides felt so intense that it was better to steer clear of the subject unless you were up for a furious debate. While Macs and PCs still both have passionate followings, the differences between the two types of computers have dramatically lessened over the years. The result is your decision comes down to subtle preferences—but you really can’t go wrong with either choice. It has become less a matter of hardware and software than of style and personal taste.

The Ecosystem: Do You Think Less Is More or More Is More?

When you buy a Mac, you’re buying a philosophy as much as a piece of computer technology. The same company produces the hardware and software, and the computers share an aesthetic sensibility with Apple* phones and tablets. Mac offers just six computer styles with a limited choice of configurations—a “best of the best approach” that eliminates the need to wade through an excessive amount of options. If you don’t like deliberating over RAM, disk space, and other hardware components, Mac does much of the work for you.

With PCs, roughly a dozen major manufacturers produce the hardware, and most run the Windows operating system. You can have hundreds of choices of style and configurations, allowing you to find exactly what you want, though it may take more time and deliberation. Whether more is more or less is often in the eye of the beholder.

Price: Look Beyond the Price Tag

Macs have long carried a reputation for premium pricing compared to PCs, though advocates would say that was simply the cost of higher-end components that provide better performance and reliability.

Making an apples-to-apples comparison on price for PC vs. Mac has always been difficult, though, because PCs and Macs typically have different pre-installed software and components, such as graphics cards, ports, and processor speed. The standard model Macs tend to offer less memory and hard drive space, so you need to take the specs into consideration.

Because of their lower cost, PCs have often been the choice for people who needed basic computing functions, like word processing and web surfing, while creative professionals who perform tasks such as design or video editing have been willing to shell out extra money for the apple of their eye. That said, the premium for the Apple know-how has shrunk to a couple of hundred bucks, making price a smaller consideration.

Maintenance: Are You a Troubleshooter?

Just as Macs offer a narrow number of choices, the systems tend to stay as they are – typically only the hard drive and RAM can be upgraded. PCs, coming in so many models from so many vendors, usually allow any of the individual hardware components to be switched out, from the central processing unit (CPU) to the displays. Whether that matters may depend on how you use the computer, how long you plan to keep it, and whether you are adept at handling some of your own maintenance.

Because Apple makes both the hardware and software, you have one primary place to turn when you have an issue, and issues can usually be resolved quickly. With PCs, different vendors make the hardware and software, and problem solving can be more complicated. Partly for this season, Apple has always received high marks from Mac owners for customer service.

Software: Your Choice May Be Up in the Clouds

In the past, it was easy to pick a Mac or PC based on the type of software you needed. Business productivity tools were domain of the Windows operating system, while editing, photo and other creativity apps were clearly a Mac world.

And though the PC tends to dominate in the workplace, many software programs for professional use—including Microsoft* Office and the Adobe* Creative Suite—have versions for both operating systems. The software has also become a smaller issue as many people no longer load software on their computer but maintain subscriptions for software they can access via the cloud. If you stream videos on YouTube, for example, your browser doesn’t care what type of computer or operating system you’re using.

Playing Games: Close the Window on This One

Gamers have always flocked to PCs, and that won’t change anytime soon. PCs can now stream games from Xbox One and PlayStation 4, and the number of titles available on a PC dwarf the Mac. So if gaming is more than just fun and games in your house, the PC wins hands-down.

Getting Touchy-Feely: PCs Emphasize Speech and Touch

For all the passion of Mac users, PC advocates can now honestly say they have a more touchy-feely relationship with their computers. Recent versions of the Windows operating system have embraced touch and speech, such as the new feature Cortana* in Windows* 10, which enables voice commands to schedule appointments. Apple has integrated its voice recognition software, Siri, into its desktop models but has been resistent to introduce a touch feature into its operating system, OS* X.

So if you prefer speaking to your computer, or moving your finger across the screen, to a keyboard and mouse, PCs offer a clear advantage.

Security: Mac Still Gets the Nod

At one time, PCs were known for frequent crashes, but the Windows operating system has become significantly more reliable. While Mac hardware and software is denoted by its stability, the difference here has lessened.

The odds of getting a virus or malware with a PC remain higher than with a Mac, but this is more about the numbers game than technology. About 7.5% of the computers in use are Mac, according to IDC, so hackers spend more time and creativity attacking PCs.

That said, a sprinkling of Mac-attacks have begun to appear, such as last year’s Keyranger ransomware which attacked the OS* X operating system and encrypted all files on a hard drive until users paid an extortion fee. The proper antivirus program and other safeguards will keep either system safe, but PCs will be at greater risk.

The Choice:

PCs and Macs do offer some clear-cut differences; which of those differences are the most important is something that each person has to decide for his or herself. Due to price and availability, PCs tend to be the winner, while Macs remain the choice for the more elite or anti-Windows computer users. Either way, you can’t really go wrong. It truly is the golden age of computers.
