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.

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.
