If you really want to toggle GPIO's faster you should look into
GPIO.out_w1ts, GPIO.out_w1tc, GPIO.out1_w1ts.val, GPIO.out1_w1tc.val

Re: ESP32-S3-WROOM-1 Disconnects USB when entering boot mode
If memory serves, go into menuconfig and enable "Channel for console output". Program it using the TX / RX pins, and reboot it.
It should then be able to flash using USB.
It should then be able to flash using USB.

Re: How to detect ESP restart from upgrade
What about running a checksum on the flash, and comparing that value to the last value saved.Yes I have thought of that, but I was looking for something non-user dependent (during testing you don't change versions all the time).

Re: Adafruit library for MCP23017 is Not working when using new Arduino Nano ESP32 development board (Arduino IDE).
Just curious, why would ESP team try to fix something that Adafruit wrote?I hope ESP team will consider this issue seriously.

Re: esp32-s3 i2c failure in esp-idf 5.2
Try using the setup for the examples folder. It's a bit different than what you have.

Re: Can reversed polarity damage GPIO?
My question is if dealing with the reversed polarity could damage the GPIO pin or even the whole board. Basically Yes, If you look at the schematic for the board 5v goes through a 2k resistor to one end the led and the other goes to the the charge controller (pin 1). To be safe you could either A) ...

Re: ESP32 - Battery powered on demand
Just use a transistor or fet to power your PIR, and control it though a GPIO pin.
