Re: Can a LED be directly connected to GPIO33-GPIO37 on ESP32-S3?
Not 100% sure what flavor ESP32-S3 you have, but check this link: https://docs.espressif.com/projects/esp-idf/en/latest/esp32s3/api-reference/peripherals/gpio.html#gpio-summary Further down on that page you will see this. Strapping pin: GPIO0, GPIO3, GPIO45 and GPIO46 are strapping pins. For more in...

Re: ESP32 Dual Core Wifi ?
But my real question is, would it be feasible (even advisable) to run the HTTP Client code (Responsible for POSTing out data) on 1 core, and the HTTP Server on another? Would the cores share the WiFi hardware nicely? I realise it's probably way overkill, but I'm in big time learn mode here (New to ...

Re: Simple Time Counter (stopwatch)
Just curious, what the issue with #include?More simple, withOUT 3 #include!
You already #include arduino.h, and that one line pulls in a ton of stuff.

Re: Question about ESP32-S3 without uart bridge
FWIW, in all my designs using the ESP32-S3 USB interface pins I dont have to use BOOT + RESET to get it into programming mode.
It works the same as if using the serial interface.

Re: The W5500 + SPI_Slave driver does not work stably.
Just for curiosity, have your tried the ethernet basic example? IDF, takes care of inialising W5500.
I used it and never had a problem with it.
