567 pages on SD cards and it uses a PIC and SPI for all the examples. This is close to useless - to get reasonable performance from SD cards (ie anywhere near published speed) you have to use full SD card protocol and a multibit data interface. (Having a proper hardware SD card controller is almost essential.) The book is also out of date - in the sample chapter it states that the maximum capascity micro SD memory card is 4Gbyte but Amazon are selling 32Gbyte Sandisk products today. Better save your money and trawl the net for more up to date and general information. MK
