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.

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

Features

Timers

This chip has more timers, each with more features than the atmega328p. Explore, configure and visualize timers for both atmega328p and lgt328p with this online tool https://github.com/dbuezas/arduino-web-timers image

Differences to original core Larduino_HSP v3.6c

  • Support 32 Mhz and other clock speeds
  • Selectable ADC resolution (Arduino compatibile default is 10 bits)
  • Differential Amplifier API
  • Better Boards Menu
  • Installation via Board Manager Urls
  • SoftwareSerial @32Mhz
  • FastIO ported from https://github.com/LGTMCU/Larduino_HSP

Power consumption @ 5v

PS: Just want to say thanks for this git, helped me a lot!

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
