Description

This document is intended to provide fundamental information on how to write and read information to-and-from a DIABLO-16 FlashBank. It contains a working example that has been dissected to properly demonstrate the manner by which the process is done. The example for this application note makes use of a text file initially stored on a micro-SD. The file will then be copied to the FlashBank and then accessed to display the information that was contained therein. It should be noted that this application note is limited to using the currently available flash memory allotted for FlashBanks that is 32Kb.
