    ESP32 Deep Sleep Wake Stubs 5 days left

    Code need to work on Arduino IDE with espressif/arduino-esp32 1.0.6 I need to detect a very fast pulse end moment (10-15ms lenght) but since ESP32 takes +200ms to start up, it's must be done from wake stubs 1. Esp32 it's in deep sleep or hibernation mode 2. HIGH pulse interrupt and wake up 3. Wake stub looking for LOW/Falling 4. Wake stub detect LOW/Falling , take the time into variable and wake up as normal 5. Normal operation, print how many microseconds elapesed from LOW time Note: Your stub code must be boot up in less 10ms, otherwise it will not be able to capture the moment from HIGH to LOW Use what ever gpio number for interrupt (DEVKIT-C) Image included for better understanding

    Hello there! I need someone to help me with a Nextion+Arduino project that I am working on. What I want you to do is to check the files that I have already made using Nextion Editor and Arduino to talk to each other. I'd like you to check them, improve them in terms of looks, operation and help me with what's undone. Basic idea is we have a display and Arduino and we want them to talk to each other all time and make the changes on Arduino side, I also have an I2C based battery fuel gauge IC so I'd like you to help me to track it's SOC as well. If you are someone who has worked with Nextion Displays and can do this, kindly bid. I'd prefer it if you have the display at your end and can test the firmware on Arduino and test the HM...

    I made an ESP32 receiver-webserver program (ESP-now protocol in Arduino IDE) but what is missing from my code is the following: I want when we make a refresh on the receiver's webpage the data to be preserved (imagine that 10 senders for example send each of them just a string as their own id for being recognized by the receiver and a char message like "free" or "duty" which make the corresponding region-square for the particular sender green (free) or red (duty) on receiver's webpage. What now happens is: If I refresh the page all the squares start from green. I thought as a solution: the senders to send every for example 30sec the last message that they have sent but that means the senders all the time are awaken up (via timer) so as to send again the...
