Arduino is not exactly our favorite. Actually, that is not the way electronics DIY works are done. Although, PAPERduino and our method for DIY shield decreases the total cost of ownership, we actually dislike that Arduino IDE. We Can Easily Start Arduino C Programming Tutorial With OS X CrossPack-AVR IDE. With Plain Homebrew We Can Install the IDE & Upload Code.
Arduino C Programming Tutorial : Any Benefit of Using C?
Do you like to do SSH and install the required software or use a script for auto-install Nginx PHP5-FPM? Auto-install script automates for many installations per day. Arduino IDE is a wrapper around GCC and the language is using C/C++. The advantage of using standard functions gives the ability to run the same program on an AVR or an ARM etc. In others we want to bypass the Arduino functions. For that we the data sheet for the specific microcontroller and interface with the chip’s hardware directly. These steps requires more work, but resulting program will be smaller and should run faster. We do not like the Arduino IDE and preprocessing language, we want to work with pure C.
If you are a complete newbie, you should have iTerm2 -Homebrew-OS X-ZSH in our way. That is factually kind of Standard.

Arduino C Programming Tutorial + OS X CrossPack-AVR IDE
AVR-GCC/WinAVR can be used with Xmega series. The AVR-GCC toolchain (with avr-libc) has a good user base at avrfreaks.net
. It was not easy. But :
1 | brew install Caskroom/cask/crosspack-avr |
We are talking about these :
1 2 | https://github.com/caskroom/homebrew-cask/blob/master/Casks/crosspack-avr.rb https://github.com/obdev/CrossPack-AVR |
and this :
1 | https://www.obdev.at/products/crosspack/index.html |
now run :
1 2 | brew tap osx-cross/avr brew install avr-libc |
We pulled avr-binutils
and avr-gcc
. As Homebrew repository doesn’t has the avr-gdb
formulae yet, we installed in that way. These are pure GNU stuffs. If you type avr-
and hit tab twice, you’ll see what are installed. AVR-GCC is a toolchain for software development, but it is not going to write the hex file to the microcontroller. So we need to install AVR Downloader – avrdude
. So run –
1 | brew install avrdude --with-usb |
Here is manual :
1 | http://download.savannah.gnu.org/releases/avrdude/avrdude-doc-5.10.pdf |
for deb GNU/Linux, we would install in this way :
1 | apt-get install gcc-avr binutils-avr gdb-avr avr-libc avrdude |
Run :
1 | sudo dmesg | grep CrossPack-AVR |
you’ll see that FTDI driver while installing Arduino IDE actually normally working.
I saw a very good example here to work with, Makefile
and main.cpp
are kept there :
1 | https://gist.github.com/maxatwork/68cdff378db18c0c808c |
From that example, you can start in this way :
1 2 3 4 5 6 | mkdir hello cd hello touch main.cpp touch Makefile make make upload |
I saw some other examples written in C :
