You might be better off asking the VisualGDB support resources; this is not an issue that is common with our own tools.

Hah, I worked with AVRs for a long time myself as well. It was actually a pretty large step for me to move from assembly to C; I still have so many old .asm files around... The ESP32 ecosystem is fairly different in that sense: because the chip is so much more powerful, it also is a fair bit more co...

Any chance you can post your code, or preferably a whittled down version of the code that does the bare minimum and still shows the issue?

A define is a preprocessor thing, and at the stage that gets resolved the system isn't aware of anything deep like 'functions' yet; the preprocessor sees your C code as plain text where it needs to do find&replace operations defined by the #define statement. In other words: as long as you put the #d...

Your tick frequency (by default) is 100Hz, so 0.5mS is less than a tick. That gets rounded down to 0, making the vTaskDelay not do anything.

Suggest you either use an esp_timer callback, or something like a hardware timer to do the thing you want.

I meassured power supply voltage (using ULP AD converter on ESP32 since it is the only available AD converter when main cores are at sleep) with pin directly connected to power supply, generated on laboratory voltage source generator, which I could manually adjust from 2.800V to 3.600V and I always...

I have no idea where you got the idea that the ADC measures relative to the voltage line. It doesn't; the ESP32 has an internal reference voltage of about 1.1V (exact voltage is stored in the eFuses) and the ADC measures relative to that, with an optional attenuation.

Don't be sorry, I am very glad somebody from Espressif comments on my sorrows. Please continue to comment. I personally really like the ESP32-C3, but I honestly tend to work with the things ESP-IDF gives me (I mean, I help developing it, so I'm pretty much biased to think it's pretty good). - Dot p...

Honestly, the ESP8266 by now is a 'mature' product meaning we will still produce the chips and fix security issues etc, but for any new things it makes a lot more sense to go with an ESP32-ish chip. The ESP32-C2 has variants that are cheaper than the '8266, but are more powerful and have more RAM si...

How can I solve this problem and deactivate the watchdog? Please don't shoot the messenger watchdog; it probably barks because you're doing stuff in your gptimer interrupt that you're not supposed to do. You can post the code so we can get an idea, but generally you want to only put trivial functio...
