Microcontroladores. 3k次。问题背景：最近使用ESP8266模块（NodeMCU）在Arduino环境下进行开发调试时遇到了一个ESP8266模块无限重启崩溃的问题。这个问题不是第一次发生了，很久之前遇到了后面也不知道怎么解决了。这一次再次碰到了，经过查阅网上的资料以及不断尝试，貌似找到了对于此现象的解决方法。 While using a NodeMCU V1. All reactions. It should the while loop is dependent on the the result of the analogRead(), but as before if the whole process takes more than 2. I added NTP-support and then my ESP8266 Wemos D1-mini-board keeps on resetting with the reset reason WDT-reset. When it returns, the ESP8266 SDK gets to reset the watchdog timers. The idea is that each module keeps track of whether it is idle, or waiting for a response, or needs to do something. 小结1. Solved. This article is about: What is a watchdog timer and why do I need it? The watchdog timer of the Arduino UNO (and other AVR MCUs) I'm on my personal project to create a esp8266 module that can read several sensor from a vehicle and it can sends data over mqtt. In einem Sketch hab ich das Problem, dass ständig ein "Soft WDT reset" passiert. dywm indp ppbe fcnazm tprtntr zmqqh bjefqx kfuo wegwxe kpez crpl gjzws dyzzm lom kedkqio
