A Linux driver to connect PATA/IDE directly to GPIO

Going the other way, a PATA port in PIO mode can be used as GPIO: <a href="https:&#x2F;&#x2F;hackaday.com&#x2F;2011&#x2F;02&#x2F;03&#x2F;stk200-pocket-change-programmer&#x2F;" rel="nofollow">https:&#x2F;&#x2F;hackaday.com&#x2F;2011&#x2F;02&#x2F;03&#x2F;stk200-pocket-change-program...</a>

An interesting project I found on twitter. Interfacing PATA&#x2F;IDE directly to Raspberry Pi’s GPIO is pretty trivial and manages to transfer 500 KiB&#x2F;s. Enough to play CDs. The driver code is around 500 LOC.

This is a fun hack. FWIW, similar sorts of things can be used to add a PATA drive to a Cortex-M microprocessor like the STM32 series.<p>Who doesn&#x27;t want a micropython board with gigabytes of code space ? :-)

&gt; Data transmission is well outside the design scope of libgpiod.<p>But it can do it, anyway. Lovely hack.

I was just watching ‘Anna’ on Hulu, and was thinking about IDE drives.<p>This does look really cool.

I wonder if you could implement a floppy interface the same way?
