platform-espressif32 VS arduino-esp32

It seems like Espressif are in the same situation as Pi w/r/t PlatformIO[1]. As an outsider, it sounds like PlatformIO was trying to extract a very large annual payment from RPi and Espressif, and that was after the initial support was added in, and some of the community started adopting it.

It's a weird situation, but I think PlatformIO built up a dominant position by supporting all these platforms and accepting community contributions to do so, then tried extracting value from the manufacturers directly after the fact, blocking further community PRs that would add new board revisions or fix bugs.

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.

ESP32: Necessary in order to establish a Wi-Fi connection with the ESP32 CAM.

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]
