esp32-camera/examples missing "PRIV_REQUIRES esp_psram"
Greetings, I believe the example camera code needs to include "esp_psram" in its top level CMakeLists.txt. Otherwise (on ESP32) it fails to allocate its frame buffer, as the code tries to place it in PSRAM due to CAMERA_FB_IN_PSRAM. Without esp_psram, the PSRAM component does not show for "idf.py me...

Re: Unable to achieve 10k samples using ADC continuous mode example code for ESP32.
Hi,
you could have a look at this code sample, below. It doesn't actually use the buffer contents but that part is straightforward (use bits 11..0 of the returned 16 bit data)

ESP32 continuous ADC sample rate incorrect?
Greetings, this question relates to the ADC on ESP32, observed on two different WROOM-modules. I'm using ESP-IDF 5.2.1, and code is based on "examples\peripherals\adc\continuous_read". It appears to me that the actual ADC sample rate - that is, the amount of generated data in a given time interval -...
