Instructions | ESP32 WiFi instant Camera

1

Get the components, an Espressif board and one of the Arducam SPI (best OV5642)

Before I suggested to get a 2 Megapixels OV2640 since generates a smaller JPG. But after many reports of burned outside pictures I suggest to start directly with a OV5642 with more resolution (Up to 5 Megapixels and exposure control in the User interface)
2

Connect them together following the schematics

ESP32 schematics live now on this branch https://github.com/martinberlin/FS2/tree/board/esp32-oled (Also board/esp32 stable)
3

Get the C++ code from Github. develop branch (ESP8266) and board/esp32* (ESP32)

Get all required libraries that are mentioned in the project and any other I forgot pressing the Verify in Arduino. If you use Platformio there is an ini file with 5 library dependencies here:
https://github.com/martinberlin/FS2/blob/board/esp32/platformio.ini
Pre-requisites: Have the ESP core for your board in the Arduino installed and also SPIFFs data upload plugin
https://github.com/esp8266/arduino-esp8266fs-plugin / https://github.com/me-no-dev/arduino-esp32fs-plugin (Spiffs is used for the user interface templates)
4

Upload the SPIFFs using the bigger space for your board

For Wemos D1 I used 3 MB SPIFFs. In the flash memory the web templates are saved so without this nothing will work
5

Prepare some PHP upload endpoint

In this repository you will find: upload.php and another upload-xbm.php that returns a JSON with an XBM image as an array (Only for the board/esp32-oled)
https://github.com/martinberlin/php-gallery This will serve also as a very nice Bootstrap gallery to browse your uploaded photos
6

Test that everything works (Electronic + Upload) and 3D print a case

7

Put everything together and start taking pictures. Don't forget to connect first to access point CAM-autoconnect and set up the WiFi for the camera
