 This is a clone of OpenCV (from commit 8808aaccffaec43d5d276af493ff408d81d4593c), modified to be cross-compiled on the ESP32. This Readme explains how to cross-compile on the ESP32 and also some details on the steps done.

-The tests were done on the ESP32D0WDQ6 (revision 1):
+A demo has been made using the **TTGO Camera Plus** module (https://github.com/Xinyuan-LilyGO/esp32-camera-screen). The board embedds an ESP32-DOWDQ6 with: 
 
 - Xtensa dual core 32-bit LX6 uP, up to 600 MIPS
 - 448 KB of ROM for booting and core functions
 - 520 KB of SRAM for data and instructions cache
 - 16 KB SRAM in RTC
 - 8 MB of external SPI RAM
-- 16 MB of external SPI Flash
