Re: possible to rename the ESP32S3 USB JTAG/serial debug unit for android ?
No, sorry, the USB serial/JTAG unit cannot be renamed. However, the ESP32S3 also has an USB OTG peripheral, switchable to use the same port. That hardware does allow for reconfiguration. (You probably want to look into the TinyUSB examples, I think that has some stuff with custom descriptors.)

Re: Problems while compiling the project Hello_World
The errors you mention all sound like IDE issues. Have you actually tried compiling the project? For the first run, CMake resolves a bunch of dependencies etc, without that IDEs are generally incapable of finding everything.

Agree, I'll move it to there.

Re: SPI problem
Hard to say. For issues like this, you generally want to own at the very least a cheap logic analyzer, or they get very hard to debug.

Re: ESP32 C3 boot loop
Ah, never mind, I thought you used the USB-serial-JTAG converter; if you're using an UART to program the chip, my advise is not applicable. In that case, I don't have specific advice. Suggest you check the power rails, if the UART signals look good, etc, perhaps there's an issue there. You could als...

Re: How to work with atomic esp32 operations (disabling interrupts)
You would use a critical section (docs).

Re: Code reusing while using interrupts
It's possibly easier to create a FreeRTOS task for this. Task waits for e.g. a semaphore or queue, then handles the sensors. Either your interrupt or your normal code can raise the semaphore or put something in the queue and let the task handle the thing.

Re: HTTPS cancel download of large file
Smells like something is not properly re-entrant, which causes the spurious errors. Is there a way to handle the cancel in the download task, as in, the cancelling task raises a semaphore, the download task checks that and calls esp_http_client_close() function?

Re: Turning potentiometer crashes esp32
That does not look like a potentiometer (potentiometer specs mention resistance, not pulses). More likely it's a rotary encoder instead.
