This library enables access to OV2640 camera on AI Thinker ESP32-CAM module in ESP32 Arduino environment. It is ported from ESP32 Camera Demo, and tested with AI Thinker ESP32-CAM board.
In ESP32 Arduino, the board type should be set to "ESP32 WROVER" to enable 4MB external PSRAM. Otherwise, internal RAM is insufficient to support resolution higher than 160x120.
