HAPPY NEW YEAR EVERYONE! we're ticking down the new year safe and sound here at home together, with a big mug of cocoa, and a lot of floppy hackin'. tonight we started adding 'greaseweazle' support to our arduino floppy library. this will let us use any fast-enough arduino hardware with a fabulous open source flux parsing tool that is written in python. basically, we send the flux pattern for each track over usb serial for it to be parsed or saved on a computer. we have been adding each command throughout the day: enabling the motor, running a bandwidth check, setting drive parameters, etc. we are halfway through the track reading code - we got the read data arriving safely at the computer, but it seems that there is a way to 'encode' the index pulse into the flux stream and we have to figure out what polarity and data format its expecting. still, feeling really close! hopefully will be able to dump our first disk image this weekend :) code is here while its being worked on https://github.com/adafruit/Adafruit_Floppy/blob/main/examples/greaseweazle/greaseweazle.ino interfacing with floppy disks at low level, part 4 https://blog.adafruit.com/2021/12/30/interfacing-with-floppy-disks-at-low-level-part-4/ https://youtu.be/a-zH9wdNwnE Reading floppy disk data, part 3! itsa pulse party https://blog.adafruit.com/2021/12/29/reading-floppy-disk-data-part-3-itsa-pulse-party/ https://youtu.be/kynoLRQpDnU Adding floppy disk support to CircuitPython, step 2 https://blog.adafruit.com/2021/12/28/adding-floppy-disk-support-to-circuitpython-step-2/ https://youtu.be/frnJ7pWr5Zg Adding floppy disk support to CircuitPython, step 1… https://blog.adafruit.com/2021/12/28/adding-floppy-disk-support-to-circuitpython-step-1/ https://youtu.be/ceyM6vYpT74 #floppy #adafruit #retro Visit the Adafruit shop online - http://www.adafruit.com ----------------------------------------- LIVE CHAT IS HERE! http://adafru.it/discord Adafruit on Instagram: https://www.instagram.com/adafruit Subscribe to Adafruit on YouTube: http://adafru.it/subscribe New tutorials on the Adafruit Learning System: http://learn.adafruit.com/ -----------------------------------------
