Re: ESP32-S2 flashing with built in USB

Note that you may still want to have a boot/reset button (or other method, like a header) on your board, as the DTR/RTS implementation is in software: the USB driver emulates a CDC-ACM serial port and looks at the 'virtual' DTR/RTS lines on that to reset the chip into download mode. If the software ...

Re: Download tool v3.8.5 and ESP-prog issue

ESP download tool uses the serial port (TX/RX, plus IO0/Reset to get the device into download mode automatically), not JTAG.

Re: Flash Encryption

Sure, you could, and you could run it through a 'decompiler', but that would hardly give you back the original source code. There certainly is merit to flash encryption, just wanted to correct any notion you would be able to retrieve the original sources from the flash at all.

Re: Help ESP32-CAM PB with ESP32D0WDQ6 (revision 1) not with ESP32D0WDQ5 (revision 1)

From memory, the 5 and 6 indicate the physical package the chip is in; electrically both are identical and should act entirely the same. That suggests your problem is elsewhere.

Re: what is use of SD0-3 io pins on esp32 ?

These also have a GPIO number, so technically you can address them like any other GPIO. However, note that normally, these pins are connected to the internal flash of the module/chip/devboard you have; in that case, reconfiguring them as a GPIO will likely crash your program. Check the datasheet of ...

Re: GPIO logical AND

Okay, I guess that is a way I did not think of. Happy I was proven wrong :)

Re: Flash Encryption

Note that you can't download the source code even from an unprotected ESP32; all that's in the flash is the compiled binary of your program. (Given we're talking about an ESP-IDF or Arduino project.(

Re: Are there any example sketches?

You mean for ESP-IDF? If so, there's a plethora of examples included in the ESP-IDF SDK.

Re: Any help for make a WebCam (USB) with ESP32-cam

The ESP32 does not have native USB; most devboards have an on-board USB-to-serial converter instead. As these are fixed-function devices, you can't re-program them to a webcam interface. You could theoretically connect a separate USB device chip to the ESP32 to make it function as a webcam, but as n...
