My source file for connecting a PIC to an IDE disk is here: test.c
It is written/developed in Hi-Tech PICC. The Hi-Tech provided delay.c and delay.h are also
part of the project.
What it does:
IDE INTERFACE PART | My Circuit |
16 Bit Bidirectional data bus | PORTB ('IDE_DATA_LOW') and PORTC ('IDE_DATA_HIGH') |
3 Bit Register Address bus | PORTE ('IDE_ADDR') |
/WRITE | PORTC bit 0 ('IDE_WR') |
/READ | PORTC bit 1 ('IDE_RD') |
/CS0 | PORTC bit 2 ('IDE_CS0') |
/CS1 | PORTC bit 3 ('IDE_CS1') |
/RST | PORTC bit 4 ('IDE_RST') |
