ata18.c

Read single block (with block-size set by CMD16 to 512 by default)
AtaReadSector( lba, ReadData )
Write: 512 Byte-Mode, this will not work (read MMC and SD-card specs) with any other sector/block size then 512
AtaWriteSector( lba, WriteData )

fat1618_2.c

Card present check. If present check valid FAT16 primary partition.
FindDrive2()
Scan directory
FileSearch2(file, mode)
Point to next sector in file
FileNextSector2(file)
Read sector into buffer
FileRead2(file)

hardware.c

Disable A/D, Setup ports, Serial 115200 bps
HardwareInit()
Send SPI?
SPI(byte)
Send byte to FPGA configuration
ShiftFpga(data)
