Interfacing IDE hard drive with 82C55 microcontroller
Have you ever thought about of having huge amount of backup memory in your embedded system. The only cheap way is to connect IDE hard drive. And it seems that interfacing IDE isn’t that hard as it may seem. The software provided for download doesn’t support any of file system formats like FAT16, FAT32 or any other.
