Example use cases are to allow re-configuration of a device's WiFi / MQTT / Blynk credentials. This library is based on, modified, bug-fixed and improved from [`Stephen Denne's DoubleResetDetector`](https://github.com/datacute/DoubleResetDetector) to add support to ESP8266 and ESP32 using EEPROM, SPIFFS and LittleFS besides original RTC. Currently, [`DoubleResetDetector`](https://github.com/datacute/DoubleResetDetector) only supports ESP8266 using RTC memory. This library can be used to detect a double reset within a predetermined time to force the program to enter a special operation such as Config Portal, Clear Default Data, etc., using : 1. EEPROM, SPIFFS or LittleFS for ESP8266 and ESP32 boards. 2. RTC memory for ESP8266 boards (unadvised). #### Currently supported Boards This [**ESP_DoubleResetDetector** library](https://github.com/khoih-prog/ESP_DoubleResetDetector) currently supports these following boards: 1. **ESP32, ESP32_C3, ESP32_S2 and ESP32_S3 boards, using EEPROM, SPIFFS or LittleFS**. 2. **ESP8266 boards RTC memory, EEPROM, SPIFFS or LittleFS** --- --- ## Prerequisites 1. [`Arduino IDE 1.8.19+` for Arduino](https://github.com/arduino/Arduino). [![GitHub release](https://img.shields.io/github/release/arduino/Arduino.svg)](https://github.com/arduino/Arduino/releases/latest) 2. [`ESP32 Core 2.0.2+`](https://github.com/espressif/arduino-esp32) for ESP32-based boards. [![Latest release](https://img.shields.io/github/release/espressif/arduino-esp32.svg)](https://github.com/espressif/arduino-esp32/releases/latest/) 3. [`ESP8266 Core 3.0.2+`](https://github.com/esp8266/Arduino) for ESP8266-based boards. [![Latest release](https://img.shields.io/github/release/esp8266/Arduino.svg)](https://github.com/esp8266/Arduino/releases/latest/). SPIFFS is deprecated from ESP8266 core 2.7.1+, to use LittleFS. 4. [`LittleFS_esp32 v1.0.6+`](https://github.com/lorol/LITTLEFS) for ESP32-based boards using LittleFS with ESP32 core v1.0.5-. To install, check [![arduino-library-badge](https://www.ardu-badge.com/badge/LittleFS_esp32.svg?)](https://www.ardu-badge.com/LittleFS_esp32). **Notice**: This [`LittleFS_esp32 library`](https://github.com/lorol/LITTLEFS) has been integrated to Arduino [ESP32 core v1.0.6+](https://github.com/espressif/arduino-esp32/tree/master/libraries/LITTLEFS) and you don't need to install it if using ESP32 core v1.0.6+ --- --- ## Installation ### Use Arduino Library Manager The best and easiest way is to use `Arduino Library Manager`. Search for `ESP_DoubleResetDetector`, then select / install the latest version. You can also use this link [![arduino-library-badge](https://www.ardu-badge.com/badge/ESP_DoubleResetDetector.svg?)](https://www.ardu-badge.com/ESP_DoubleResetDetector) for more detailed instructions. ### Manual Install 1. Navigate to [ESP_DoubleResetDetector](https://github.com/khoih-prog/ESP_DoubleResetDetector) page. 2. Download the latest release `ESP_DoubleResetDetector-master.zip`. 3. Extract the zip file to `ESP_DoubleResetDetector-master` directory 4. Copy the whole `ESP_DoubleResetDetector-master` folder to Arduino libraries' directory such as `~/Arduino/libraries/`. ### VS Code & PlatformIO: 1. Install [VS Code](https://code.visualstudio.com/) 2. Install [PlatformIO](https://platformio.org/platformio-ide) 3. Install [**ESP_DoubleResetDetector** library](https://registry.platformio.org/libraries/khoih-prog/ESP_DoubleResetDetector) by using [Library Manager](https://registry.platformio.org/libraries/khoih-prog/ESP_DoubleResetDetector/installation). Search for **ESP_DoubleResetDetector** in [Platform.io Author's Libraries](https://platformio.org/lib/search?query=author:%22Khoi%20Hoang%22) 4. Use included [platformio.ini](platformio/platformio.ini) file from examples to ensure that all dependent libraries will installed automatically. Please visit documentation for the other options and examples at [Project Configuration File](https://docs.platformio.org/page/projectconf.html) --- --- #### HOWTO Usage How to use ```cpp // These defines must be put before #include // to select where to store DoubleResetDetector's variable. // For ESP32, You must select one to be true (EEPROM or SPIFFS) // For ESP8266, You must select one to be true (RTC, EEPROM, LITTLEFS or SPIFFS) // Otherwise, library will use default EEPROM storage #ifdef ESP8266 #define ESP8266_DRD_USE_RTC false //true #define ESP_DRD_USE_LITTLEFS true //false #endif #define ESP_DRD_USE_EEPROM false #define ESP_DRD_USE_SPIFFS true #define DOUBLERESETDETECTOR_DEBUG true //false #include //https://github.com/khoih-prog/ESP_DoubleResetDetector // Number of seconds after reset during which a // subseqent reset will be considered a double reset. #define DRD_TIMEOUT 10 // RTC Memory Address for the DoubleResetDetector to use #define DRD_ADDRESS 0 DoubleResetDetector* drd; #ifdef ESP32 // For ESP32 #ifndef LED_BUILTIN #define LED_BUILTIN 2 // Pin D2 mapped to pin GPIO2/ADC12 of ESP32, control on-board LED #endif #define LED_OFF LOW #define LED_ON HIGH #else // For ESP8266 #define LED_ON LOW #define LED_OFF HIGH #endif void setup() { pinMode(LED_BUILTIN, OUTPUT); Serial.begin(115200); Serial.println("\nStarting minimal example for ESP_DoubleResetDetector"); drd = new DoubleResetDetector(DRD_TIMEOUT, DRD_ADDRESS); if (drd->detectDoubleReset()) { Serial.println("Double Reset Detected"); digitalWrite(LED_BUILTIN, LED_ON); } else { Serial.println("No Double Reset Detected"); digitalWrite(LED_BUILTIN, LED_OFF); } } void loop() { // Call the double reset detector loop method every so often, // so that it can recognise when the timeout expires. // You can also call drd.stop() when you wish to no longer // consider the next reset as a double reset. drd->loop(); } ``` --- --- ### Examples 1.

To enable debug: ```cpp // Use this to output debug msgs to Serial #define DOUBLERESETDETECTOR_DEBUG true ``` --- ### Troubleshooting If you get compilation errors, more often than not, you may need to install a newer version of the `ESP32 / ESP8266` core for Arduino. Sometimes, the library will only work if you update the `ESP32 / ESP8266` core to the latest version because I am using some newly added function. --- --- ### Issues ### Submit issues to: [ESP_DoubleResetDetector issues](https://github.com/khoih-prog/ESP_DoubleResetDetector/issues) --- --- ### TO DO 1. Search for bug and improvement. ### DONE 1. For ESP32 and ESP8266 (EEPROM, SPIFFS and LittleFS). 2. Similar features for Arduino (UNO, Mega, SAM DUE, SAMD21/SAMD51, nRF52, STM32, Teensy, etc.). Look at [**DoubleResetDetector_Generic**](https://github.com/khoih-prog/DoubleResetDetector_Generic) 3. Add support to `ESP32_C3`, `ESP32_S2` 4. Add support to `ESP32_S3` using ESP32 core v2.0.2+ --- --- ### Contributions and thanks 1. Thanks to [zobix](https://github.com/zobix) for report the bug in [Isssue 2](https://github.com/khoih-prog/ESP_DoubleResetDetector/issues/2) 1. Thanks to [Tochi Moreno](https://github.com/tochimoreno) for enhancement request in [DRD is waiting for a double reset? #14](https://github.com/khoih-prog/ESP_DoubleResetDetector/discussions/14) leading to v1.3.1 to add `waitingForDRD()` function to signal in DRD wating period
