Command line Arduino builds

Now that I have the Arduino up and running, I knew I wanted to use my editor of choice and command line build tools.

There is of course the alternative of using the Arduino IDE as a command line tool, but it still felt too clunky for my needs.

Secondly, there is the Arduino Makefile project, which would be a better fit, was it not... you know... make. And I saw a few results for CMake when googling, don't get me started.

So, again, I set out to create my first built scripts.
I looked at these instructions and changed it slightly for my needs. I also looked here.

$ brew tap osx-cross/avr
$ brew install avr-libc avr-gdb
$ brew install avrdude --with-usb

After that, I looked at the verbose output from the Arduino IDE to figure out most settings. And I also compared them to other packages (Arduino-make etc).

In the end, I got this build.sh

Monitor

To communicate with the Arduino (e.g. displaying the debug output), I use "screen" on osx (On windows there's PuTTY).

You quit "screen" with ^A+K:

$ screen /dev/cu.wchusbserial1410 9600

Foot note:

I compared the turnaround time between my script and Arduino-make:

./build.sh:

$ time ./build.sh
real 0m3.264s
user 0m0.185s
sys 0m0.100s

Arduino-make:

$ time (make -f ../Makefile && make -f ../Makefile verify_size reset do_upload)
real 0m6.275s
user 0m1.224s
sys 0m1.120s

That's 3 seconds longer. That's going to get annoying real fast! Of course you get a ton of extra features, but I just don't need them.
