// ArduCAM Mini demo (C)2017 Lee
|
||||
// Web: http://www.ArduCAM.com
|
||||
// This program is a demo of how to use most of the functions
|
||||
// of the library with ArduCAM ESP8266 2MP/5MP camera.
|
||||
// This demo was made for ArduCAM ESP8266 2MP/5MP Camera.
|
||||
// It can take photo and send to the Web.
|
||||
// It can take photo continuously as video streaming and send to the Web.
|
||||
// The demo sketch will do the following tasks:
|
||||
// 1. Set the camera to JPEG output mode.
|
||||
// 2. if server.on("/capture", HTTP_GET, serverCapture),it can take photo and send to the Web.
|
||||
// 3.if server.on("/stream", HTTP_GET, serverStream),it can take photo continuously as video
|
||||
//streaming and send to the Web.
|
||||
|
||||
// This program requires the ArduCAM V4.0.0 (or later) library and ArduCAM ESP8266 2MP/5MP camera
|
||||
// and use Arduino IDE 1.6.8 compiler or above
