The Teensy microcontroller got a firmware update :slight_smile:

  1. Persistent flash memory
  2. Flash memory file handling
  3. Autostart from flash
  4. Built in SD Card file handling (Teensy 4.1)

Here a small example:

import teensy
const fs = teensy.fs
const FS_WRITE = 1

file = fs.open("flash:/test.txt", FS_WRITE)
file.write("test\n")
file.close()

You can upload console.bas to the Teensy to get a command line interface with commands like ls, cd or cp to manage your files. Type “help” to get a list of all available commands.
