Build Arduino-based libraries without IDE

This repository contains all required infrastructure to allow you to build your Arduino projects without actually having an IDE nearby.

You are free to forget about *.ino files and Arduino IDE, just setup the toolchain, use main.cpp as a skeleton and you are free to go.

NOTE: only Arduino Nano board were tested (I only have this guy). But the base Makefile should work for any Arduino-based libraries.

AVR Toolchain

In order to be able to compile under GCC and upload firmware files you need:

• avr-binutils
• avr-gcc
• avr-libc
• avr-dude

Our installation directory will be /usr/local/avr/ and OS is Fedora.

Linux (Fedora) Prerequisites

sudo dnf install gmp gmp-devel mpfr mpfr-devel libmpc libmpc-devel flex

avr-binutils

wget https://ftp.gnu.org/gnu/binutils/binutils-2.29.tar.bz2
tar -xvjf binutils-2.29.tar.bz2
cd binutils-2.29
mkdir build && cd build
../configure --prefix=/usr/local/avr/ --target=avr --disable-nls
make -j8
sudo make install

avr-gcc

wget http://ftpmirror.gnu.org/gcc/gcc-7.1.0/gcc-7.1.0.tar.bz2
tar -xvjf gcc-7.1.0.tar.bz2
cd gcc-7.1.0
mkdir build && cd build
../configure --prefix=/usr/local/avr/ --target=avr --enable-languages=c,c++ --disable-nls --disable-libssp --with-dwarf2  
make -j8
sudo make install

avr-libc

wget https://download.savannah.gnu.org/releases/avr-libc/avr-libc-2.0.0.tar.bz2
tar -xvjf avr-libc-2.0.0.tar.bz2
cd avr-libc-2.0.0
mkdir build && cd build
../configure --prefix=/usr/local/avr/ --build=`../config.guess` --host=avr
make -j8
# Note: because `install` target that runs `/bin/sh` can't find `avr-ranlib` no matter what
# (expanding PATH doesn't work), we do `make install` from root
su -h
cd PATH_TO_AVR_LIBC
sudo make install

avr-dude

# Note: make sure only flex is installed: no bison/bison-devel is installed
wget https://download.savannah.gnu.org/releases/avrdude/avrdude-6.3.tar.gz
gunzip -c avrdude-6.3.tar.gz | tar xf -
cd avrdude-6.3
mkdir build && cd build
../configure --prefix=/usr/local/avr/
make -j8
sudo make install

Using Makefile

You can run make help in order to get all the information about possible targets and avalable options to change.

In general the flow is as follows (assuming you want to compile with Wire default Arduino library and immediately after upload to the board):

1. Update main.cpp file - put your logic in there.

2. Compile project

make BAUD=57600 PORT=/dev/ttyS0 BRD=AVR_NANO WITH_WIRE=1 all

3. Upload the binary to the board

make upload
