In this tutorial, we will see how to store data in flash memory of ESP32 using the Preferences.h library and Arduino IDE. We can use this library to read and write data on the ESP32’s flash memory permanently. Flash memory is like a long-lasting memory that remembers things, so it’s perfect for saving important information. … Read more
In this tutorial, we will see how to retain or remember the last state of GPIO pins on the ESP32 board after a reset using the Preferences library in Arduino IDE. Normally, when the ESP32 loses power or restarts, the previous state of the output is lost, causing potential disruptions in the system. However, with … Read more
In this tutorial, we will see how to erase the flash memory of an ESP8266 using the esptool.py command-line utility in Windows, Linux, and MacOS, and discuss why and when you might want to do this. As with any electronic device, there may be times when you need to reset the ESP8266 to its factory … Read more

In this short guide, we will learn how to upload files to the ESP32 SPIFFS (flash file system) using VS Code with PlatformIO IDE. To show the working of the SPIFFS in VS Code, we will create and store a simple .txt file in the filesystem. Recommended Reading: Getting Started with VS Code and PlatformIO … Read more
In this tutorial, we will show you how to install a file system uploader plugin in Arduino IDE to upload files to ESP8266 NodeMCU flash (LittleFS). By default, there is no support in Arduino IDE to upload files to ESP8266 flash filesystem. But we can install a plugin to add a file uploading feature in … Read more
In this tutorial, you will learn how to program a PIC Microcontroller compiler software called MikroC. This is a simple and user-friendly software designed to convert the C-language code into a hex file, which can then be fed to the microcontroller to perform specific tasks. After completing this tutorial, you will be able to generate … Read more
