About

pyavrutils is a Python library that can build AVR and arduino code at runtime.

Links:

• home: https://github.com/ponty/pyavrutils
• documentation: http://ponty.github.com/pyavrutils

Features:

• python wrapper for avr-gcc, avr-size, arscons
• build files or strings (strings are saved as temp files)
• MCU list
• get code size using avr-size
• avr-gcc default is optimized for size
• supported python versions: 2.6, 2.7

Known problems:

• temp files are not removed
• arscons does not perfectly matches the Arduino build process

Possible usage:

• experimenting with flags
• building from paver
• unit tests
• building arduino code without GUI

Basic usage

>>> from pyavrutils import AvrGcc
>>> cc = AvrGcc()
>>> cc.build('int main(){}')
>>> cc.size().program_bytes
66

>>> from pyavrutils import Arduino
>>> cc = Arduino()
>>> cc.mcu = 'atmega8'
>>> cc.build('void setup(){};void loop(){}')
>>> cc.size().program_bytes
1612

Installation

General

• arscons is already included in the library
• install pip
• install gcc-avr
• install scons (only for arscons)
• install arduino (only for arscons)

if you have setuptools installed:

# as root
pip install pyavrutils

Ubuntu

sudo apt-get install python-pip
sudo apt-get install binutils-avr
sudo apt-get install gcc-avr
sudo apt-get install scons
sudo apt-get install arduino
sudo pip install pyavrutils
# optional for examples:
sudo pip install entrypoint2

Uninstall

using pip:

# as root
