avr-utils README

Welcome to avr-utils.

This extension helps users to write and compile code for their avr microcontrollers straight from the comfort of their favourite Code editor, VScode

!! New !!

• Progress bar when downloading toolchain.
• Better error message diagnostics (Big Improvement!)
• Simplified Commenting of code.

Features

• Projects: Creating and importing

  • >> Create Or Import

    

    You can create a new avr project or import an existing project created from Microchip/Atmel studio.

    After making a choice, VSCode will ask you to choose a folder.

    • If opening a Microchip project, it asks for the project folder of your existing project.
    • If creating a new project, it asks for the folder to put the project in, then it asks for a name for the project (then asks for permission to load the project if you already have another project open in the editor).
      
      

  • >> No Toolchain?

    You may want to build the opened/newly creared project, but you encounter a popup saying you have no toolchain.

    Don't worry, you just have to download a new toolchain (you don't have to have Microchip Studio), or if you already have Microchip Studio on your device, you can choose to take time to locate the folder within the install directory of Microchip Studio which has the name "avr8-**" and contains the following folders, or at least 90% of them.

    
    

    Generally, I recommend downloading a new toolchain to save you the time.

    

  • >> Select a device first

    

    Before running a successful build in c, you need to select a microcontroller so that avr-gcc does not give build errors.

    ---

    

    Once you build the project successfully, you will get a .elf file, a .hex file and an .o file created for you within the Debug folder in your project.

    

• Code Completions

  • >> Toolchain headers and Project headers

    Within the "main.c" file or any other project file in c, you can get completions for the avr-gcc headers or the project-level headers.

    

  • >> Header document links

    You can easily open header files if you need to read documentation or edit them through the links provided as shown below.

    

• Object Definitions

  • >> Device header files

    After selecting a device, you can access it's definitions like for registers like DDRA or PORTA. If the device has a register, you can press Ctrl or Cmd and click the register variable using your pointer to get taken to the definition, and of course if the register doesn't exist on the selected device, you won't get definitions.

    

    Of course, this works on variables and functions too.

  • >> Project header files

    Header files within the project directory can also contribute to the definitions. In general, any file that you "#include" will contribute to the definitions.

    

Command Palette Contributions

The extension comes with some settings added to the command palette. Press Ctrl+Shift+P or Cmd+Shift+P and type "AVR Utils" to view them.

• Open Microchip Project: You can use this to open a project folder for a project created using Microchip Studio (a.k.a Atmel Studio)

• Create Project: This is used to create a new project. This command also creates for you some very minimal boilerplate code in c to get you started.

• Build/Compile: This command only appears when the project has been opened and there is an active c file.
  Take note that this command can also be invoked simply by pressing F5 on your keyboard, or by the Build button at the bottom of the VSCode window.

Settings Contributions

The extension also now has some settings accessible from Ctrl+, or Cmd+, and then search for "AVR Utils":

• Show terminal at each build: This setting is useful to ensure that there are no build errors arising from your code since an extension cannot directly get stdout from the terminal to parse errors. You can turn this off in case you don't need it.

Known Issues

If you have the extension ms-vscode.cpptools installed, it will cause red squiggles in your code, plus it will create extra buttons in the ui which may not build your AVR.
Therefore to solve this, I registered a new language called "AVR C" which handles the same file extension .c and so if you need to use your IDE for normal C development, you can just switch the language as shown below.
