Arduino
=======

Version 1.8 of Arduino (as installed from debian packages) is ok.

Setup
-----

* Under File → Preferences, add the espressif URL to the Additional
  Boards Manager URLs field. (on 2024-09-04 that's
  ``https://dl.espressif.com/dl/package_esp32_index.json``).
* Under Tools → Board → Boards Manager make sure that you install a
  version of esp32 by Espressif Systems that is above 2.0 (on 2024-09-04
  there is a 3.0.4 that works).
