TTGO-Camera-Series

• Now Arduino officially supports the camera, you need to update the Arduino to the latest, see arduino-esp32 for details.I am using the 1.0.1rc2 version when writing this code.

• In order to support BME280, I will use Adafruit_BME280_Library, but this library conflicts with <esp_camera.h> and enters Adafruit_BME280_Library In Adafruit_BME280_Library change <Adafruit_BME280.h> --> 29 lines comment #include <Adafruit_Sensor.h>, BME280 this library does not use this header file, so comment out and no problem

• OLED requires esp8266-oled-ssd1306 library support

• Buttons require OneButton library support

Board Modify

• The Camera 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 esp32-camera-bme280.ino line 12)
• Add OV2640 microphone version board support, need to enable TTGO_OV2640_V16 macro for pin conversion, no microphone test, need microphone test please use T-Camera

• Note1: The T-Camera Plus I2C is parallel to the camera SIOD SIOC. If you want to use other I2C devices, you need to change the driver code of the underlying driver camera. For details, please refer to [esp32-camera-screen] (https://github.com/lewisxhe/esp32-camera-screen)

• BUTTON Click: Reverse camera Currently the camera reverse color will not be normal, see issues#9

• BUTTON LongPress : Enter sleep Mode , Sleep current 6.9mA

• RESET BUTTON: When the battery is powered, click to turn on the power

• PIR: Detecting human motion and will display the first screen
