Contents
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)
main.c
- PIC Hardware init.
- SD-Card init.
