There are two main problems with using printf in an ISR: amount of stack consumed, and amount of processing time taken. ISRs usually have a limited amount of stack space allocated, and usually have limited time to perform its task. You can usually configure your ISR stack space to be larger and that...

I installed IDF 5.01 but there are a lots of legacy lacking. Need to install the proper one but I can't find any reference and initial setup is gone (New computer). Once you figure out what IDF version you want to use, you can check the version migration guides in the ESP-IDF documentation. Dependi...

The Feather board has pins labeld USB (power?) and BAT. If one of these takes 5Vdc in to power the board, perhaps you could wire one of your USB-C connectors to it (power and ground).

You haven't really said what moving "to an enclosure" means in terms of everything else. Since you refer to not wanting to "mount the board" near the edge, I assume you mean a development board (as others have suggested)? If you want to use the 3.3v or 5v supply pins on the development board then, y...

@leemoore1966, I'm glad you ask. Yes, I found a solution. As a little background, here is my situation, in contrast to the original response I received to my question: I have an application that does not require the embedded web pages (or "web application") to operate since it operates with a REST A...

I assume you mean you have an ESP32 development module that has a USB port that, when connected to your PC, Windows 11 Device Manager doesn't recognize it? If that's the case, your ESP32 module uses a particular USB to UART bridge chip and Windows 11 may not have a native driver for it. Check your d...

You don't have to start from scratch. But I assume that the simple OTA example has the URL of the binary as well as the binary file name hard-coded in the code. So to access a different file and/or a different URL location for the file, that's a code change and rebuild. As far as the cert goes, as l...

What headaches are ahead using C? I assume all the ESP32 libraries are all in Python?

Nope. ESP-IDF is written in C. You can find the source code on github.

Hm. Having a space in the user name there can be problematic for some programs... Maybe moving your .espressif folder to a new location and setting the following environment variables accordingly will work? What you could try is to dump out your environment variables and check which ones reference t...
