OK more floppy fun, this time with jepler helping out – we’re doing some cross-platform code sharing where the mfm decoding C code is going to be the same for arduino and circuitpython. jepler wrote up the mfm-decoding-and-crc-verifying for circuitpython and it was pretty easy to integrate it into arduino so that we can not just read flux data but the actual binary data! here we’ve got a simple floppy track dumper that goes from track 0 to 80, alternating sides, and prints the hex and ascii output. and, now you can see why we went with text files as a test bed – its very easy to see that our cross-sector reading is correct because the text continues smoothly from one to the other. this means we’re getting close to being able to access the file system in arduino which means we are ONE STEP CLOSER to building a project ladyada has wanted since she was a teenager (can you guess what it is?) anyways, code is here for the curious https://github.com/adafruit/Adafruit_Floppy/blob/main/examples/mfm_test/mfm_test.ino & video.
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 firstname.lastname@example.org 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 code.org, 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.
