About:

AVR4L aims to deliver an easy to use and user friendly Integrated Development Environment for developing Codes for microcontrollers based on Atmel's AVR families. AVR4L is a Creative coding / Integrated Development Environment for Linux operating systems intended for AVR beginners as well as professionals, it has many features from professional IDEs as well as the simplicity of editing.

Installation and Running:

Linux:

1. Make sure Java JDK / JRE v1.8 is installed on your computer.
   1. How to install: https://java.com/en/download/help/linux_x64_install.xml
   2. Set JAVA_HOME environment variable, by doing the following:

      1. Depending on where you installed your Java, you will need to provide the full path. For this example, I installed Oracle JDK 8 in the /usr/lib/jvm/java-8-oracle directory.

      2. Open the file /etc/environment and scroll to the end of the file and enter the following:

         JAVA_HOME=/usr/lib/jvm/java-8-oracle

      3. Save and source the file by doing:

         . /etc/environment or source /etc/environment

2. Clone/download this folder to your computer.
3. cd into the Binaries/Linux directory.
4. run sudo -E ./install.sh within this folder.
5. you can now type avr4l in any terminal session or find it in the dash if you have Ubuntu installed.

Windows:

1. Make sure Java JDK / JRE v1.8 is installed on your computer.

   1. How to install: https://java.com/en/download/windows_offline.jsp

2. Clone/download this folder to your computer.

3. cd into the Binaries\Windows\installer project\AVR4L-SetupFiles directory.

4. (recommended) install AVR4L Setup.exe

5. or run the AVR4L.exe directly from the portable folder.

   note: windows version is not fully tested and may be unstable, it is intended for cross platform compatability.

   note: if you want to use the portable version you must make sure that portable\avr-tools\bin and portable\tools\bin directories are added to the PATH system environment variable.

   The project's full focus is on the linux version as it aims to be an alternative to Atmel's Studio for linux users.

Features:

1. Cross platform (Linux, Windows)
2. Creative coding environment with auto-complete, suggestions and many more features.
3. Two options for compiling and uploading your code:
   1. standard mode.
   2. makefile mode.
4. Compiling .c files of various atmega parts or microcontrollers.
5. Uploading .hex files to various atmega parts or microcontrollers.
6. Supports many programmers:
   1. AVR-ISP (avrisp)
   2. Atmel STK500 Version 1.x firmware (stk500v1)
   3. Arduino (arduino)
   4. USB-ASP (usbasp)
7. Console area shows results of compilation and uploading.

Known Issues:

1. Upload fails with message permission denied: AVR4L requires super user permissions to upload sketches, you can either:

   1. sudo avr4l from a terminal

   2. or add your user to the dialout group, most programmers are listed in this group:

      sudo adduser YOUR_USER dialout

      note: replace YOUR_USER with your linux user

2. Upload fails with message sudo no tty present and no askpass program specified: AVR4L requires super user permissions to upload sketches, but has not been run as root (sudo), so when it tries to issue a command with sudo, there is no way for it to get the root password, so you can either:

   1. sudo avr4l from a terminal

   2. or prevent sudo commands from requesting passwords:

      in a terminal type:

      sudo visudo

      and add the following to the end of the file:

      YOUR_USER ALL = NOPASSWD : ALL

      note: replace YOUR_USER with your linux user
