Hello. I try to add ESPino32CAM to my project. i copy it to libraries folder. ESPino32CAM include folder "quirc" but when I try to compilling project from example, I got an errors:

Hey there.

Make sure use the right hardware as PSRAM is required (the ESP32CAM has one).
Inside Arduino\libraries\ESPIno32CAM\src\ESPino32CAM.h you have to Set-Up the pins for your camera accordingly.
