Programming 32-bit Microcontrollers in C

Day 14 Mass Storage

The Plan

In many embedded-control applications, you might find a need for a larger nonvolatile data storage space well beyond the capabilities of the common Serial EEPROM devices and the Flash program memory available inside the microcontroller itself. You might be looking for orders of magnitude more—hundreds of megabytes and possibly gigabytes. If you own a digital camera, an MP3 player, or even just a cell phone, you have probably become familiar with the storage requirements of consumer multimedia applications and with the available mass storage technologies. Hard disk drives have become smaller and less power thirsty, but also a multitude of solid state solutions (based once more on Flash technologies such as Compact ...
