 Hello everyone, I'm Tim, and in this video I'll show you my latest project. This is a CircuitPython-powered text editor that's capable of being taken on the go thanks to the Feather RP2040 USB host port allowing us to connect a USB keyboard and the 3.5-inch TFT featherwing display allowing us to see our files and their contents. CircuitPython 9 has brought us support for USB host, which means the keyboard is automatically recognized by the system and its key presses will input to the REPL or programs based on the standard input stream like this one. With this simple editor, you can select from the files on your CircuitPy drive to open them and view their contents. If your device storage is mounted in writable mode, you can modify and save changes to the files as well. I've connected a simple push button to an otherwise unused pin and set up the boot pie script to check the state of that button to select whether it will mount as writable or read-only. Check out the learn guide if you'd like to make one for yourself.
