Can the WDT be routed to a GPIO pin

As most of us know when you starve the CPU core your going to get a WDT warning in the terminal.
I am curious if there is some kind of ISR hook or other call that can be implemented in code so that if it gets triggered I can toggle a GPIO pin.

Re: 5V tolerance

Going forward, do you guys think you'll officially support 5v tolerance? It would be a nice feature to have and make interfacing much easier in many cases. There is like a bazillion of devices out there that do this for super low cost. Ever since the first micros that went from 5v to 3.3v this issu...

Re: Unexpected ADC offset in ESP32

"The ADC should be configured before reading is taken." as per the docs, has this been done in your code ?

Re: triggering WDT in OTA

If its inside a do loop then you need to stick a delay in there. Otherwise your starving the WDT.

Re: ESP32 to ESP32 local communication

If serial speeds will work for you then use serial port 1 on both ESP32's to talk to one another.

Re: CMAKE how to use typedef enum declared in component

That is because there is already a file config.h in the file system. Even though you rename it to Config.h (Capital "C") does not matter.

Renaming it to say "Config_mine.h" works for me.

Re: Bad flash command line generation with CMake

Sorry for the delay in getting back to you. I've checked and this is a bug in the v3.3.1 CMake build system, will fix ASAP I am curious. If we used esp-idf-tools-setup-2.2.exe to install v3.3.1, when there are any fixes are they applied to v3.3.1 or some later version? If applied to v3.3.1, when th...

VSPI will be mush, much faster than I2c.

Re: How to connect a D1 Mini to a PCB?

You can do this 2 ways. #1) Create the PCB to use headers like you normally would. Place the D1 on top of your PCB. From the bottom side of your PCB, insert the headers through until they just hit the top edge of the D1 then solder them from each side and snip off the excess. I.E. your just using th...
