Detailed Description

IDE driver.

This driver is based on Atadrv by Hale Landis but it is completely rearranged for the minirighi32.
IMPORTANT!!!
Here you can find what the driver should expose to the rest of the world.

Read IdeAta, IdeLow, IdeDebug and IdeTimer comments for better understand how this driver works. Implementing new ide commands is very very simple. All the major part of the Ata protocol is in "IdeAta.c". You only need to look for Ata-4 references, search for a command and see what protocol and what parameter you have to use. I have written specific subroutines to read, write and identify identifying devices, but they only simplify the interface for the more generic ata protocol.

I have already set inizialization of Ide Driver in main.c so you only need to:

• select the channel you want to use (with SelectAtaChannel);
• check CurrentChannel to find a specific device (directly with CurrentChannel var);
• use one of the specific command sub (i.e. ReadSectorLba, WriteSectorLba, ...)
