  • 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)
