AP-484 Interfacing a Floppy Disk Drive to an 80C186EX Family Processor

Embedded applications often deal with data collection and analysis. Attaching a floppy disk drive to an embedded system allows data collection with the possibility of analyzing the data on a PC Compatible system. This Application Note describes how to interface a 80C186 family processor to a floppy disk drive and read/write in the PC DOS compatible format. The floppy driver does not allow execution of EXE or COM files, it is strictly for data transfer. A simple example of how to use the floppy driver to write random numbers to a DOS file is also provided. The source code and this Application Note are available on the Apps BBS (916-356-3600) as FDCAPP.EXE.
