Working code for interfacing to Atmel AT49F040 FLASH memory, should work with other Atmel FLASH memory in the same family. This FLASH memory doesn't need long block write times, making it a good choice for realtime data acquisition. A 20 MHz PIC can write over 8000 4-byte samples per second.
Example source code and JPG schematic included. Source code contains routines to read, write and erase. One write routine is optimized for code size, the other is optimized for execution speed.
