Your code is very interesting ! with nice features….
But i have also some problems :

ESP12, 2A powered, Arduino 1.6.5 then now 1.6.6 « hourly », ESP8266 1.6.5-804-g2d340c7…. your 1.1.3 version

When i suppress ALL « PROGMEM », things goes a little better (page ‘config network’ still crash)
Sometime, ESP respond quickly, sometime it seems to be ‘over killed’ ????
I try with Safari, Firefox....

I should be very happy to have this thing operational !!!

Thanks….

Please keep in mind that you have to select the right memory amount of your chip when compiling and programming the chip.

These settings are working fine for me:

ESP-01 1M (512K SPIFF)
ESP-12 4M (3M SPIFF)

I also use Visual Micro as IDE because I like the code completion and the serial monitor.

In the Arduino IDE (which I am very grateful to the developers for) there are the following boards available: Generic, Olimex and NodeMCU. I have the NodeMCU selected for the ESP-12.

As a result of many tests of using and removing the PROGMEM keyword, I believe PROGMEM, when used more than once in a program will overwrite or erase the contents of a previously 'saved' PROGMEM constant char string.

At least this occurs on my particular hardware model. Two different devices of the same model were tested with the same results.

This always will result in a WDT program crash when a previously known good page is selected from the menu.

To make debugging even more entertaining, seemingly random page serve freezes occur when the FreeMem heap size drops much below 10000. System crashes are guaranteed for me if the heap size drops below 5000.

I am pleased to say, my ESP-12 water irrigation controller based on the WebConfig template is working well if the above requirements are met.

- Wed Jul 22, 2015 5:08 pm #23963 The attached program is based on WebConfig without the web config. It uses a hardcoded static IP address.
This is a first pass effort at an irrigation timer. It is no where near production ready. There are no integer type checking or range checking of user entered values for instance. There is no error trapping or other production software basics.

To use this create a folder called Irrigation_1 inside your MySketches directory.
Download and unzip the attached files into the Irrigation_1 directory.
Open Irrigation_1.ino and add your router ssid, password and a valid static IP address for your network setup.

Tested only on an ESP-12.
