Beware that ESP32's generally use cheap NAND flash memory which is rated for a maximum of maybe 100,000 writes. SPIFFS performs wear-leveling, which will help avoid writing to the same location in flash over and over again, but eventually it will still wear out. Webspiff sgen.py. spiff sgen.py is a write-only Python SPIFF S implementation used to create filesystem images from the contents of a host folder. To use spiffsgen.py, open Terminal and run: python spiffsgen.py <image_size> <base_dir> <output_file>. The required arguments are as follows:WebOne option is to buy an ESP32 board with PSRAM fitted and copy the SPIFFS image to PSRAM at boot up. You will then get much faster random access to the data set just using pointers. If PSRAM is available, the TFT_eSPI library uses that memory area and technique for Sprites, so examining the Sprite.cpp file in the library may help you figure it out.Saving a block of flash every 20 milliseconds, you're going to use that up pretty quick. https://www.esp32.com/viewtopic.php?t=709 You'd have to come up with some way of storing data the minimum number of times, maximizing the data consumed within a spiffs/flash block and distributing writes across all the available flash.Apr 22, 2020 · In this post I’m gonna explain my experience of creating a web server to input data in various data types using ESP32 and Arduino IDE. ... {Serial.begin(115200); // Initialize SPIFFS #ifdef ...
