I'm using it in memory mode, but while searching the web I found an audio player project which did use CF in IDE mode. If you google for "Compact Flash" IDE you should find it.

Hi,
here's what I wrote. It's been able to read a sector from the CF card.
Note it's :
1/ directly ported from a very useful SanDisk AN that can be downloaded here :romuald
void wait_ready(void) { while((cf[STATUS_REG] & 0xF0) != 0x50); }
void wait_drq(void) { while((cf[STATUS_REG] & 0xF8) != 0x58); }
void read_sect(const unsigned long num) { wait_ready(); cf[SEC_COUNT_REG] = 0x01; cf[LBA_LOW] = num; // No need for a cast... cf[LBA_MID] = (num >> 8) & 0x000000FF; cf[LBA_HI] = num >> 16; cf[DRV_HD_REG] = 0xE0; cf[COMMAND_REG] = 0x20; wait_drq(); get_data(); }
void get_data(void) { uint i; xdata char * data b;
b = IDE_BUF; for(i=0;i Dear list,
code?
