PBP and a hard dirve?

[Normnet]

IDE HD Sure
See IDE Hard Disk experiments.
Includes Hex file for PIC16F1870 and schematic.
I haven't tried but it looks doable.

Should be a PIC16F870

On the to do list.

Thanks for the link Norm.

He uses a 4014 8-bit static shift register:

Do we have to do the same? Is there any reason why we couldn't just use 8 pins on a PIC?

I glanced at Tilmann's page and he doesn't make any reference to that chip. He does say this though:

The data bus carries the 16-bit data words to and from the
host. However, when accessing the control and status
registers of the IDE drives, only data bits 0 through 7 are
used (8-bit transfer). The data bus lines are tri-state
lines that may be connected directly to the host's data bus.
However, to meet the host bus specs and to avoid noise
problems caused by the interface cable, a bus driver IC
should be used to decouple the IDE bus and the host bus.

The code supplied is HEX only so you will initially have to go with the existing setup as in the schematic.
The hardware and PIC/PC software shown is for learning however perhaps later a PIC with more pins could replace the 4014 but test as you go.

I wasn't really planning on using his code. I was mostly interested in the commands, schematic and procedure to interface with an IDE drive.

Old post but did you have any luck with the IDE hard drive interface?
I am giving it a try again.

Not yet. I'm working on setting up a small inventory system using my phone as scanner. I've reached the point of buying stuff I already have.

It's also a good way to get all my parts organized.

You two HAVE to be joking! Wouldn't it be much easier to read a SD card instead? There is even code available.
