This is an example project for `PlatformIO `_ to build the canonical blink code for the `Digispark USB development board `_ with an Atmel AVR ATtiny85 microcontroller.

.. note::

  This doesn't use the Arduino framework, but directly uses the native AVR registers.

You can use this project as a template to build your own AVR code for the Digispark with PlatformIO.

************

Requirements

************

You need PlatformIO and the `Atmel AVR platform `_ in PlatformIO. You can install both with:

.. code-block:: shell

  pip3 install platformio

  pio platform install atmelavr

The Digispark runs the `Micronucleus `_ bootloader. If you've bought it recently, the bootloader is a recent version that isn't supported by PlatformIO's older ``micronucleus`` command. Therefore, you need to build the newer version of the command. On Ubuntu or Debian this goes like this:

.. code-block:: shell

  git clone https://github.com/micronucleus/micronucleus.git

  cd micronucleus/commandline

  sudo apt install libusb-dev

  make

  sudo make install

The `platformio.ini `_ file in this example project defines a custom command to refer to the ``micronucleus`` command you've built.

*****

Usage

*****

Build the code with:

.. code-block:: shell

  pio run

Build and upload the code to the Digispark with:

.. code-block:: shell

  pio run -t upload

Plug in the device into a USB port of your computer when asked.

If you want to use this project as a template for your own projects, have a look at the `GitHub Action `_ file. It automatically builds the code on each push and pull request and checks for errors and warnings. There's also a `Makefile `_ to make checking and building code easier.
