Explore the differences between SPIFFS and LITTLEFS file systems for ESP32 and ESP8266 microcontrollers in this informative video tutorial. Learn how to utilize the built-in flash storage on these devices instead of relying on SD cards for small file storage. Discover the advantages of LITTLEFS over the deprecated SPIFFS, including improved resilience and power interruption protection. Follow along as the tutorial guides you through installing necessary libraries, setting up the Arduino IDE, and configuring partition parameters for ESP32. Get hands-on experience with uploading files to the microcontroller's file system and writing sketches to read those files. Gain valuable insights into efficient file management for your ESP8266 and ESP32 projects, enabling you to make better use of the onboard storage capabilities.
