ESP8266_WebGen

Design a website and then embed it in the ESP8266 firmware. This project is now subdivided into three different sketches:

• AdvancedWebServerHuzzah: This is a very basic example that lets you choose either acting as an access point or as a wifi client.
• AdvancedWebServerHuzzah_APandClient: This one is similar to the basic examples except that it includes the ability to switch between the access point or provide an SSID and (optional) password. This also gives examples of how to use jQuery and code-implemented URL handlers to have dynamics content on the web pages. This technique is still embedding the webpage in PROGMEM as C arrays.
• AdvancedWebServerHuzzah_SPIFFS: This final technique uses the SPIFFS flash filesystem to implement the website in FLASH memory such that the items can be retrieved just like files on an external SD card. The SPIFFS writing utility (which can be added to the ArduinoIDE following instructions at http://arduino.esp8266.com/versions/1.6.5-1160-gef26c5f/doc/reference.html) seems to require you to write the entire 3MB of reserved file space every time. This takes forever. So, in addition to the faster example when in PROGMEM above, I implemented a modified version of the Arduino WebUpdate example to allow us to upload just the HTML, JS, CSS, and image files. This can be done by sending commands like the following: curl -F "file=@css/dropdown.css;filename=/css/dropdown.css" 192.168.4.1/update. I will eventually make another Python script to generate the setup code for the webserver to retrieve the web files from SPIFF and to update all the website files on the device.

How to use the script for AdvancedWebServerHuzzah and AdvancedWebServerHuzzah_APandClient:

1. Edit the webpage as you see fit
2. Run the following command: python generate_arduino_webpage.py > website.h
3. Copy the website.h file into the Arduino project
4. Compile the Arduino project and load to the board

How to use the script for AdvancedWebServerHuzzah_SPIFFS

1. Follow the instructions at http://arduino.esp8266.com/versions/1.6.5-1160-gef26c5f/doc/reference.html to get the SPIFF data uploaded to the device at lead one time. This ensures the FLASH space is "formatted" for SPIFFS.
2. Load the AdvancedWebServerHuzzah_SPIFFS program to the board and it should start serving the website
3. Update the SPIFFS files either using curl and the "update" URL or by flashing the whole thing again from ArduinoIDE

Notes:

• In the APandClient code, you can force the device to revert to the AccessPointMode by pulling pin 12 low at startup. This resets the EEPROM, so you will have to input the ssid and password again after connecting to the device acting as an access point. I am contemplating making the device revert to an access point if it can't connect to a router for 30 seconds even when in WifiClientMode.
• This should handle any html, css, jpg, or png file
• For intereacting with hardware, you will need to add handlers for URLs that aren't static. I eventually want to improve the parser so that any links that don't have an associated HMTL file in the folder will generate a stub function.
