I read about adding/uploading image files to a “data” folder using the Arduino IDE, but not sure how to do it on Platf…. What SPIFFS does not do: SPIFFS does not support directories and uses a flat structure. Somehow finally we found the way. Now, paste the below code in the Arduino IDE. This document provides sample codes based on ESP8266_RTOS_SDK. size_t max_files¶ Maximum files that could be open at the same time. Serial-to-WiFi Tutorial using ESP8266. py and main. There is a block for the user code (the “sketch”), there is a block for the OTA update file, another one for the emulated EEPROM, another for the WIFI configuration and one for the File System. The following code should load. if you have followed above steps then, IDE status bar will display SPIFFS Image Uploaded message.
