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.
