 Okay Lady Duda what's this? Okay those are index pulses coming from this floppy drive that I am interfacing with. I just got you know the first kind of parts going where I enable the motor and I'm setting the direction. I'm going to you know get the index pulses and then I'm going to find out when it's at track zero. So basically kind of trying to read data off of this floppy drive so I can add native floppy disk support to circuit python. Soon I'll update this to maybe use the RP2040 as well. Right now I'm just writing the code in our do we know because that's what I'm familiar with so I finally get all the IDC pins set up the way I needed to. What was really helpful was this really really nice modern datasheet from Samsung for the SFD321B. So it actually goes through everything you need and so far so good. So I've just started basically getting the motor running. The floppy disk is responding so far so good. Hi!
