Hi all... I'm running into exactly the same problem that BLP had in Reply #16... I can't get the library to work with the Sparkfun SCP1000 pressure sensor via SPI. Again, as with BLP, the SCP1000 code works fine if I comment out the FAT stuff, and the FAT stuff works weather or not I comment out the SCP1000 code (but the sensor returns all zeros). I wrote my own implementation so unless he and I made the exact same mistake I'm thinking this is something in the FAT library.
I'm wondering if indeed the SD code is responding even when the SD CS_ is HIGH. Can anyone suggest any troubleshooting ideas? (I don't have a logic analyzer). SoftSPI is not an option ... Thanks in advance!
