Hi all has anybody had any problems interfacing MMC cards to an LPCxx using the SPI interface. I've previously interfaced to HC11 and AVR without any problems. I can get some cards to initialise, however some will consistently not initialise with the LPC. I seem to be missing the LSB in the response byte. The cards which won't work with the LPCxx will work fine in my HC11 and AVR systems. I've tried various bus speeds without success. Doug
