• Many people can't compile because I am compiling with the latest ESP-WHO. With the update of the official framework, some files may be removed. I re-updated to the latest framework, commit id : 258751b5b615ffdc2e0f43f8815b6ffbaeb3da03 As the framework update may not be able to compile smoothly, please go back to the ESP-WHO 258751b5b615ffdc2e0f43f8815b6ffbaeb3da03 repository to compile.

• The SCCB driver in esp-who uses the IO emulation method. I rewrote it to I2C to drive it so that I can mount multiple devices on the I2C bus ,Need to replace sccp.c in the SCCB directory with esp-who/components/esp32-camera/driver/sccb.c (Esp-who is now configured by default as a hardware I2C driver)

• At present, the program is not stable, and the wake-up of the voice conflicts with a certain part of the program. Since the voice wake-up code cannot be viewed, this problem cannot be solved. The code just demonstrates that the TTGO Camera Plus board hardware is intact.

• Since TTGO Camera Plus does not have physical buttons, face information entry will be entered on the web page.

• Turn on the FACE_DETECT_IN_SCREEN macro(in main.cpp), face recognition will be displayed in the display, and the microphone will be disabled. The web page will not be viewable. Only face input and camera parameters can be adjusted.

Board Modify

• The Camera Plus version sold by TTGO will not have the BME280 sensor, because the temperature on the board affects the accuracy of the sensor. The default program does not enable the BME280 function. If necessary, turn on the ENABLE_BME280 (on app_main.cpp line 35)
• In a separate screen display, the wifi hotspot is only turned on, and the connection does not respond.
