flashdemo

---------

This example demonstrates how data can be read and written to/from the

Flash memory.

During the start-up the firmware (defined in flashdemo.c) reads the number of

last sector n from sector 0 (dword at position 0) and increments it by one. If n

is larger than or equal to the total amount of sectors, or if it is equal to 0,

n is set to 1.

Then n is written back to sector 0 and sector n is filled with the string

"Hello World!".

The host software (defined in FlashDemo.java) reads out the string from the last

sector of the flash memory.
