That is, the following functions: init() IDE_ReadData() IDE_WriteData() IDE_Command(command) IDE_ReadReg(reg) IDE_WriteReg(reg, data) unsigned char IDE_Status() They are little more than I/O commands. You also need to know what commands to give, when to give them, and what to expect in reply. You have to read the IDE-to-8255 article for that. I use 16F877. Direct connect, 16 bit, no external latches. I also have a DAC connected, and am perfecting Record and Playback routines.
