Sanguino VS arduino-esp32

The first time I programmed my v1.1.4 board, I set up an Arduino Uno to use as the programmer, in ArduinoIDE 1.8.9. Then I used the board manager to install https://raw.githubusercontent.com/Lauszus/Sanguino/master/package_lauszus_sanguino_index.json to the "Additional Boards Manager URLs" field as per the instructions at https://github.com/Lauszus/Sanguino/tree/master, and installed the bootloader. That was in early 2019, and I didn't have any problems, but I believe that later versions of ArduinoIDE 2.x may be slightly different. Maybe worth trying an older version?

I believe it's the Sanguino 1284P. Have a look at the Github: https://github.com/Lauszus/Sanguino

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
