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 install a suitable version of
  esp32 by Espressif Systems: on 2024-10-04 version 3.0.2 worked.

.. note::
   As of September 2023 there was a bug in the Espressif esp32 package for
   Arduino that meant that it wasn't working with the Olimex ESP32-PRO
   board, the workaround was to use Version 2.0.9 of the package; this
   has been fixed at some point before version 3.0.2.

Programming
-----------

These are the settings used:

:Board: OLIMEX ESP32-EVB
:Upload Speed: 115200
:Flash Frequency: 80MHz
:Partition Scheme: Default
:Core Debug Level: None
:Erase All Flash Before Sketch Upload: Disabled

Troubleshooting
---------------

When using the Arduino serial monitor note that you may have to send
some data before it will start receiving from the board.
