ESP8266 DHT11/DHT22 Temperature and Humidity Web Server with Arduino IDEDid you know each ESP allows you to partition the system flash such that you can use it to store both code and support a file system? This filing system can be used to store infrequently changing data such as; web pages, configurations, sensor calibration data etc. What skills do I need? To set the system up, use the source code provided you will need the following. Did you use this instructable in your classroom? Add a Teacher Note to share how you incorporated it into your lesson. Given most of these ESP devices are sourced from Chinese suppliers who are less than forthcoming in releasing clear and concise product data, one way to figure out how big your flash is to read the chip details assuming they haven't been scrubbed and carrying out an internet search. I did this for two of my ESPs. Here the former and latter are 1M byte. Consequently, I found the most reliable and quickest method was to programme the device with the CheckFlashConfig. Once you have completed the upload, the code will execute and your serial monitor dialogue will display text as in pic 1 above. Note : If the ESP is powered down or reset, upon each successive execution a new line is automatically appended and displayed. Use of SPIFFS is a great way to store infrequently changing data though it should not be considered for applications requiring many write accesses as it will eventually cause flash to fail. A typical worked example of how long flash is likely to last is given here. Tested with the following Arduino IDE versions: 1. The procedures in step Prepare the ESP device for upload; 1. Hold down 'Flash', 2. Press 'Reset' 3. I did not know that. Thanks for the tutorial; very useful tips. Reply 1 day ago. On a nodeMCU 1. Reply 18 hours ago. Regards SteveQuinn. Reply 8 hours ago.

Post your questions here until you graduate! Don't be shy. It all works apart from 1 thing. But programatically writing the same config file from my sketch results in garbage in the file which crashes the JSON parser leading to a stack dump. My understanding is that all ESP modules can use a reserved piece of Flash memory for a pseudo filesystem based on section 4. Code: Select all WriteConfigFile: contents of config. There is an issue with these chips and spiffs. I don't know if the work around is allready included in 2. For some reason, none of my Google searches brought me to the issues in the Arduino github.
