If you want, you can also copy the board definition file https://github.com/platformio/platform-espressif32/blob/develop/boards/esp32-s3-devkitc-1.json and create a custom one in your own repo (if it differs much from the esp32-s3-devkitc-1).

On the "Platforms" tab of the quick access toolbar, I can click on "platforms" (again) and see that I have version 6.0.1 of the Espressif 32 platform instaled. If I look at the release info, it seems that support for IDF v5.0 was added in Espressif 32 version 6.0.0.

board: esp32-s3-devkitc-1 #https://registry.platformio.org/platforms/platformio/espressif32/boards

This is probably the simplest next step before fully transitioning to ESP-IDF and dumping PlatformIO. Here's the PlatformIO example repo that does just this. https://github.com/platformio/platform-espressif32/tree/develop/examples/espidf-arduino-blink

Sounds like this might be a similar issue to this problem I ran into with the S3 and Platform.io?

esphome: name: myesp32c3 esp32: board: esp32-c3-devkitm-1 variant: esp32c3 framework: ### Arduino type: arduino version: dev platform_version: https://github.com/platformio/platform-espressif32.git#feature/arduino-upstream ### ESP-IDF # type: esp-idf ...

Yes this seemed to be it. I don't know what is the difference between "development platform" and "development framework" (IDF), but all I know is that the change that made thinfs slower happened in the former. And I know that because I reverted the version used inside Platform.io. Other than that, I have no idea what is happening in the background. I just use PlatformIO on VSC and have pretty basic programming skills.

You could just buy ready-made ESP32 boards with an OV2640 camera built-in, then customize the example sketch from https://github.com/espressif/arduino-esp32/tree/master/libraries/ESP32/examples/Camera/CameraWebServer to your liking.

Are you perhaps this poster? https://github.com/espressif/arduino-esp32/issues/5250 - asking that poster for the list I just asked for went nowhere and it was auto-closed.

I have 2 ESP32-S2-Saolo-1 's on hand. I am trying to do the example Wifi FTM code that can be found at the following repo: https://github.com/espressif/arduino-esp32/tree/master/libraries/WiFi/examples/FTM

That has not been my experience at all as a user. ESPHome is even easier than Arduino and I haven’t touched firmware code in years.

The price makes a huge difference when you have dozens of them operating which is trivial with a decent hydroponics and smarthome setup. I also have a dozen boards just sitting idle ready to be called up to replace a failed one or use for a new project because they’re so cheap.

Not to mention the Arduino core is supported officially by ESP32: https://github.com/espressif/arduino-esp32

Who actually uses Arduino in production? Everyone just uses modules (for ESP32) or rolls their own using the Arduino board as a reference.

They've done a good job of hiding the RTOS from you and making most sketches run fine without porting, but you're still running as a task under the RTOS, yielding between loop() calls[1]. This leads to mysterious timing issues if you aren't aware of it[2]

It doesn't appear that the Arduino core for the Renesas chip is using the RTOS, at least by default -- its main loop is literally doing while (1) { loop(); }, similar to how the AVR core works. [3, 4]

I copied all the libraries from here: https://github.com/espressif/arduino-esp32/tree/master/libraries
