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: 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.

Re: Programmatically Initiate A Hardware Reset Circuit
Maybe something like this? Trigger it with one of your GPIO. https://www.amazon.com/HiLetgo-Trigger-Adjustable-Control-Conduction/dp/B0832MW9L4/ref=sr_1_6?crid=2AQX3POCR5PLS&keywords=digitally+controlled+power+relay+with+time+delay&qid=1707712926&sprefix=digitally+controlled+power+relay+with+time+de...

Re: GPIO interrupt not working
remove the ESP_LOGI's from the ISR handler and see what happens.
