README

        # How to install

Add the package to the arduino Boards Manager Urls:

- Go to Preferences

  - paste this url in Boards Manager URL: `https://raw.githubusercontent.com/dbuezas/lgt8fx/master/package_lgt8fx_index.json`

- Go to Tools/Board/Boards manager

  - Type `lgt8fx` in the search box

  - install lgt8fx

Now the boards appear in the IDE. You can also select clock speeds, [upload speeds and generic boards with external cystal](./docs/arduino/readme.md).









32Mhz is twice as fast as a conventional arduino nano! Actually _even faster_ as many operations take less clock cycles than in the atmega328p. Check out some [benchmarks](https://github.com/dbuezas/lgt8fx/discussions/77)

# Timers

This chip has more timers, each with more features than the atmega328p.

# Disclamer

I have no association with Arduino, Logic Green, Atmel or anything. I just wanted to have a convenient way to use these boards and get them to work without hacks at max speed

# Automated Releases

Each time a PR is merged, the release action will be triggered.

The following steps are executed

* Generate the release artefacts (the lgt8f-1.0.x.zip file)

* Update the `package_lgt8fx_index.json` file with the new version

* Commit and push those changes to the repository

* Generate a release with the artefact.

PRs that only touch the `readme.md` file, or the `/docs` folder will NOT trigger a release.

The action can be found here: https://github.com/dbuezas/lgt8fx/blob/master/.github/workflows/release.yml
