Hello Andre, > CCS compiler comes with MMC lib driver. Any pic can be used. > What compiler are you using? yes. I've bought PCD (v4.083) and theirs "DSP Analog" board for = having an alternative to Microchip. There's a book from CCS called "DSP = Analog Exercise Book" that I also bought. I went from EX1.c to EX11.c without problems. Now, EX12.C compiles = and runs, but mmcsd_init() never works. It returns 0x80 or 0xFE. I'm using their own hardware with their own exemple and libraries = and it doesn't works. Maybe it's just one more of those many CCS nasty bugs.
