where is libatomic?

I'm tying to compile something like this: #include <atomic> static int test() { std::atomic<long long> x; return x; } int main() { return test(); } but I get c:/users/username/.espressif/tools/xtensa-esp32-elf/esp32-2019r1-8.2.0/xtensa-esp32-elf/bin/../lib/gcc/xtensa-esp32-elf/8.2.0/../../../../xten...

Why the shield can?

Why have most ESP32 modules a shield can? is it to protect the esp32 from the antenna or vice versa?

If using an ESP32 pico D4, would it make sense to put it under a shield can as well?

Re: How is 240 Mhz cpu clock achieved?

I assume 'yes' means PLL_CLK runs at 480 Mhz?

What about the other clock sources?

Where can I find a version of the technical reference manual that has correct clocking information?

How is 240 Mhz cpu clock achieved?

The esp32 technical reference manual section 3.2.2 states that PLL_CLK is an internal clock with 320Mhz frequency and section 3.2.3 states: <<As Figure 6 shows, CPU_CLK is the master clock for both CPU cores. CPU_CLK clock can be as high as 160 MHz when the CPU is in high performance mode. Alternati...

ESP32 lagging every few seconds

I have a ESP32-CAM module and compiled the ESP32->Camera->CameraWebServer Arduino example on it. It works fine, however, the videostream hangs in regular intervals (every 5-6 seconds for about 1-2 seconds). I didn't make changes to the example other than entering my SSID and password. What could be ...
