Adding floppy disk support to CircuitPython, step 1…

We are adding floppy disk support to CircuitPython, here is step 1 (video), want more, sign up for the Python on Hardware newsletter, goes out in the am 🙂 💾 💾 💾 🦂 🐇 ☠️ I’m the the guest editor this week! SIGN UP HERE!

If there’s one thing we believe in strongly here at Adafruit it is that if you have an embedded interpreted language running on your microcontroller, it’s super important that you can access floppy drives from it. Sure, sure, you could use a micro SD card, but microSD cards can get lost easily compared to a chonky 3.5″. So we’re starting to look at how to get a floppy drive up and running. The good news is you can use 5V power and it seems to be ok with 3V logic levels. We’ve got the idc cabling wired up right we think, because we can now turn on the motor and see index pulses coming out at around 5Hz. This Samsung SFD-321B datasheet has been really helpful in interfacing, and so far our code is in Arduino since we’re comfy with that for hardware noodling. We’ll publish it as a cross-platform-usable open source hardware so folks can keep on spinnin’.

As 2022 starts, let’s take some time to share our goals for CircuitPython in 2022. Just like past years (full summary 2019, 2020, and 2021), we’d like everyone in the CircuitPython community to contribute by posting their thoughts to some public place on the Internet. Here are a few ways to post: a video on YouTub, a post on the CircuitPython forum, a blog post on your site, a series of Tweets, a Gist on GitHub. We want to hear from you. When you post, please add #CircuitPython2022 and email to let us know about your post so we can blog it up here.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

  1. Do please try and get it working with a 5+1/2” floppy as well.
