A file character reading challenge for SPin2 / Pasm experts.

So lets say you have a file on your SD card and you need to check what byte is at position 75 in the file.

In Spin2 or PASM how could that be done.

Just posted this FAT32 object to the OBEX. Tried to make it as simple to use as possible.

CON
  _CLKFREQ = 80_000_000
  _SD_MISO = 58                   
  _SD_SCK  = 61                   
  _SD_MOSI = 59                   
  _SD_CS   = 60                   
VAR
  byte  buffer[2048]
OBJ
  sd : "SD card driver"
PUB main()  | result
  if sd.mount(_SD_CS, _SD_MOSI, _SD_MISO, _SD_SCK)
    sd.openFile(string("filename.txt"))
    result := sd.readByte(75)
    debug(uhex_byte_(result))
