Description: We are encountering a critical issue in our microcontroller project. We are utilizing ESP-IDF and have found that versions 4.4.4 and older operate seamlessly, however, upon upgrading to version 4.4.5 or later, we face a problem causing the program to halt and subsequently reboot after several seconds. The attached log file delineates the firmware initiation and the point at which it halts. This issue is exclusive to scenarios where we attempt to create an instance of any class in our code and invoke any method of that object (e.g., cout “Hello world”). However, when we transpose the content of the aforementioned class method directly into main, it operates correctly. Key Symptoms of the Issue: The program halts with ESP-IDF version 4.4.5 or newer. Debuggin...

Circuit #1) The goal is to have a circuit to give/cut power (+3.3v / +5v) to sub ICs/sensors, command by a microcontroller pin. Must cut the input voltage (circuit must be placed between VCC and IC) = high-side switch. Circuit #2) The goal is to have a circuit to enable/cut I2C bus (+3.3v / +5v), command by a microcontroller pin. We want +3.3v and +5v sensors to be connected on the same I2C bus - what about pull-up resistor ? Remarks: If power is cut (by circuit #1), power must not leak through I2C pull-up resistors. Maybe circuit #2 is not necessary if we can be sure that no current leak through pull-up resistors when cut the power. Guidelines : - Simplest as possible (the less or cheaper components) - Easy to find component (AliExpress, Mouser, ...) - Easy to hand-sold...

The defrost cycle is not working on my home fridge. My home fridge uses the newer "Adaptive Defrost" cycle that is run by a microcontroller on the motherboard of the fridge. I don't want to replace the motherboard just for this problem so I want to bypass the problem with my own defrost control using an external ESP32 wifi-switch. EXPLANATION OF ADAPTIVE DEFROST Adaptive Defrost Adaptive Defrost can be described as a defrost system that adapts to a refrigerator’s surrounding environment and household usage. Unlike conventional defrost systems that use electromechanical timers with a fixed defrost cycle time, Adaptive Defrost utilizes an intelligent, electronic control to determine when the defrost cycle is necessary. In order to accomplish the correct defrost...
