Double Reset Detector

Library to detect a double reset, using ESP8266 RTC Memory

PURPOSE: Detects a double reset so that an alternative start-up mode can be used. One example use is to allow re-configuration of a device's wifi.

ESP32?

Will this work in an ESP32?

Add to the Arduino Library Manager for easier installation

https://github.com/arduino/Arduino/wiki/Library-Manager-FAQ

Basically i think you would need to just a properties file and move the code into a src folder and do a release.

Here is an example properties file
https://github.com/witnessmenow/Universal-Arduino-Telegram-Bot/blob/master/library.properties

I could push a PR with the changes if you want (but I would need a contact email to put in the Maintainer field)

small error when compiling with paltformio

Hi

I get this "error" when compiling with platformio.

Is there a way to fix this?

.pio/libdeps/d1_mini/DoubleResetDetector_ID1679/src/DoubleResetDetector.cpp: In member function 'void DoubleResetDetector::loop()': .pio/libdeps/d1_mini/DoubleResetDetector_ID1679/src/DoubleResetDetector.cpp:34:42: warning: comparison between signed and unsigned integer expressions [-Wsign-compare] if (waitingForDoubleReset && millis() > timeout) stop();

Get more users for this library

I think this library is really excellent and deserves more attention then it gets!

I've created a video around this library hopefully it helps raise awareness of it. I only have a pretty small channel but hopefully it helps! I'll also make a post to instructables over the next few days.

How to prevent Restart on first press?

I would like to use your library to perform "factory reset" so some code needs to be run in order to erase data after double clicking reset button.
But the problem is, that upon first press device is restarted so actually it never catch double press of reset button. How do I prevent this restart?

Adding Double Reset Detector As An example To WiFi Manager

Using a double reset to go into WiFi configuration mode which was mentioned at tzapu/WiFiManager#160 (comment) is a great concept. This has the advantage that human intervention is required to initiate WiFi configuration but avoids the requirement of an extra button to initiate WiFi configuration.

I can see two issues though:-

1. If the power supply is flaky it can be detected as a double reset and go into configuration mode.
2. The device freezes for the double reset detection interval which in the example is 10 seconds.

If this was done with RTC memory rather than SPIFFS the record of a reset disappears in the case of a power outage but remains when the reset button is pushed. This would eliminate issue 1.

Perhaps issue 2 wouldn't be too bad if the double reset time was short, say half a second, or maybe the reset flag could be cleared with a timer and callback so it is non blocking.

I'd like to add an example using using a double reset to go into WiFi configuration mode to the version of WiFiManager at https://github.com/kentaylor/WiFiManager, ideally with your help.

Nodemcu flash button ?

Hi. this is nice library but how can I define nodemcu flash button to resetting configuration ?

thanks

When connecting Wemos D1 mini via USB drd.detectDoubleReset() returns true

When connecting Wemos D1 mini via USB drd.detectDoubleReset() returns true.
Any idea why this is happening?

Write to user RTC area in example

According to ESP8266 documentation the first 256 bytes in the RTC are reserved for the system. I suggest to change the example to write to address 64 (the addressing is done in 4byte steps). See ESP8266 SDK API Guide page 19.

library.properties in version 1.0.0 shows version 0.0.2

The library.properties file in version 1.0.0 contains this line:

version=0.0.2

Incredibly useful

We can have two programs running, it's just a matter of booting into one or another, awesome stuff, thanks a lot!!
