Chapter 7. Advanced PIC18 Projects—SD Card Projects

In this and the remaining chapters we will look at the design of more complex PIC18 microcontroller–based projects. This chapter discusses the design of Secure Digital (SD) memory card–based projects. The remaining chapters of the book describe the basic theory and design of projects based on the popular USB bus and CAN bus protocols.

The SD Card

Before going into the design details of SD card–based projects, we should take a look at the basic principles and operation of SD card memory devices. Figure 7.1 shows a typical SD card.
