ArduCAM ESP8266 UNO
Introduction
ArduCAM now released a ESP8266 based Arduino board for ArduCAM mini camera modules while keeping the same form of factors and pinout as the standard Arduino UNO R3 board. The high light this ESP8266 board is that it well mates with ArduCAM mini 2MP and 5MP camera modules, supports Lithium battery power supply and recharging and with build in SD card slot. It can be an ideal solution for home security and IoT camera applications.

Pin Definition
Note that the SD/TF card CS pin is shared with UART TX signal, so the UART and the SD/TF can’t be used at the same time.
The board has build in Lithium battery charger, which accepts default 3.7V/500mA Lithium battery. The charging indicator and charging current setting can be found from the Figure 3.

ESP8266 UNO Tutorial
This Tutorial is a demo of how to use ArduCAM Mini 2MP/5MP camera module on ArduCAM ESP8266 UNO.
This demo needs:
- ArduCAM ESP8266 UNO Board(x1),
- ArduCAM Mini 2MP camera module(x1)
Step1:Installing with Boards Manager
1.Installing with Boards Manager Install Arduino 1.6.8 from the Arduino website.Starting Arduino and open Preferences window and entering the following link into Additional Board Manager URLs field. You can add multiple URLs, separating them with commas：
http://www.arducam.com/downloads/ESP8266_UNO/package_ArduCAM_index.json
//pic1
Note that the installed package source file is located in the C:\Users\Your computer name\AppData\Local\Arduino15\ folder,here is C:\Users\zk109\AppData\Local\Arduino15\ for example.
Open Boards Manager from Tools ->Board menu and install ArduCAM_ESP8266_UNO addon package.

Note if you download failed, you need to delete the C:\Users\Your computer name\AppData\Local\Arduino15\ folder, and then restart the Arduino IDE, repeat the above operation. //pic4
Step2:Using Arduino IDE
Step3:Examples
1.Installing with Boards Manager Install Arduino 1.6.8 from the Arduino website.Starting Arduino and open Preferences window and entering the following link into Additional Board Manager URLs field. You can add multiple URLs, separating them with commas:
http://www.arducam.com/downloads/ESP8266_UNO/package_ArduCAM_index.json
//PIC
Note that the installed package source file is located in the C:\Users\Your computer name\AppData\Local\Arduino15\ folder,here is C:\Users\zk109\AppData\Local\Arduino15\ for example.
Open Boards Manager from Tools ->Board menu and install ArduCAM_ESP8266_UNO addon package.
//PIC
Note if you download failed, you need to delete the C:\Users\Your computer name\AppData\Local\Arduino15\ folder, and then restart the Arduino IDE, repeat the above operation.
//PIC
2.Using Arduino IDE After installation of ArduCAM ESP8266 UNO board add-on package, you can select this board from the Tool->Board menu. And there several ready to use examples from the File->Examples->ArduCAM.You can use these examples directly or as a starting point to develop your own code. Select ArduCAM_ESP8266_UNO board from Tools->Board menu.
//PIC
Select the example from File->Examples->ArduCAM->ESP8266->ArduCAM_ESP8266_UNO_Capture
//PIC
Configure the camera setting You need to modify the memorysaver.h file in order to enable OV2640_MINI_2MP or OV5642_MINI_5MP_PLUS or OV5640_MINI_5MP_PLUS camera modules.
Only one camera can be enabled at a time.The memorysaver.h file is located at C:\Users\Your computer name\AppData\Local\Arduino15\packages\ ArduCAM_ESP8266_UNO\hardware\ArduCAM_ESP8266_UNO\ 2.2.2\libraries\ArduCAM.
//PIC
3.There are 5 examples for both ArduCAM Mini 2MPand ArduCAM Mini 5MP camera modules. (ArduCAM ESP8266 V1 has been discontinued ).
ArduCAM_ESP8266_Capture:this example uses HTTP protocol to capture still or video over home wifi network from ArduCAM Mini 2MP/5MP and display on the web browser. You can change the value of wifiType to select Station or AP mode. If you use Station mode the ssid and password should be modifies before uploading.
//PIC
AP mode: After uploading, the board IP address is 192.168.4.1. You can figure out the IP address through the serial monitor.The default serial monitor baudrate setting is 115200bps.
//PIC
From your PC , go to the WiFi setting page. You should see an Access Point (AP) which the SSID name "arducam_esp8266" on the AP scan result list. Choose the "arducam_esp8266" AP to connect to it. This AP's password is “".
//PIC
Finally, open the index.html or video.html, input the IP address obtained from the serial monitor then take pictures or videos. The html files are located at C:\Users\Your computer name\AppData\Local\Arduino15\packages\ArduCAM_ESP8266_UNO\hardware\ArduCAM_ESP8266_UNO\ 2.2.2\libraries\ArduCAM\examples\ESP8266\ArduCAM_ESP8266_Capture\html_2640.
//PIC
Also you can use ArduCAM_Host_V2.0_Windows Host app.You can download it on https://github.com/ArduCAM/Arduino/tree/master/ArduCAM/examples/host_app.
//PIC
ArduCAM_ESP8266_V1_Capture2SD(or ArduCAM_ESP8266_V1_Capture2SD):this example takes time elapse still photos using ArduCAM Mini 2MP/5MP and then stored on the TF/SD card. The LED indicates when the TF/SD card is writing.
ArduCAM_ESP8266_V1_Video2SD(or ArduCAM_ESP8266_V2_Video2SD):this example takes motion JPEG video clips using ArduCAM Mini 2MP/5MP and then stored on the TF/SD card as AVI format,about 4 minutes to complete.

A:If you have this problem,Firstly, you should check your SPI interface and i2c interface.If they work fine, you can try add some yield(); in your code.
Q4: Can't connect WIFI?
A:In our ArduCAM ESP8266 capture demo,the default mode is AP mode, when it work fine,you will see the below content in the serial port. "Share AP: arducam_esp8266 The password is: 192.168.4.1 Server started" You should search and connect the arducam_esp8266. If you want to work in station mode.just set the wifiType = 0.Then you should put your ssid and password. "const char* ssid = "SSID"; // Put your SSID here const char* password = "PASSWORD"; // Put your PASSWORD here"
Q5: Can't find the serial device number?
A: Please ensure you have install the CH340 driver on your PC.If haven't installed, you can download it from https://github.com/UCTRONICS/Drivers/raw/master/CH34x/CH341SER.EXE
Then install it .
Q6: Can't get the higher frame rate?
A: This has a lot to do with controller performance and our camera's SPI speed.
