What is Spiff in ESP32?
The ESP32 contains a Serial Peripheral Interface Flash File System (SPIFFS). SPIFFS is a lightweight filesystem created for microcontrollers with a flash chip, which are connected by SPI bus, like the ESP32 flash memory.
Can you run Python on ESP32?
Install Python on Your Computer In order to upload MicroPython programs to the ESP32, we will use a tool called ampy, which is a Python script that can read and write files to a MicroPython board over a serial connection.
How to use ESP8266 spiffs to upload files?
Ensure you have a sub-directory within your sketch directory named ‘data’, Place the files you wish to upload into the ‘data’ directory, From ‘Tools’ menu, select the correct ESP8266 device and choose the ‘Flash Size’ with the SPIFFS you require ie. ‘1M (256K SPIFFS)’. See pics 1 and 2 above,
