Arduino/Moteino library for read/write access to SPI flash memory chips.
This works with 256byte/page SPI flash memory such as the 4MBIT W25X40CLSNIG used on (Moteinos)[www.moteino.com] for data storage and wireless programming.
For instance a 4MBit (512Kbyte) flash chip will have 2048 pages: 256*2048 = 524288 bytes (512Kbytes).
Minimal modifications should allow chips that have different page size to work.
DEPENDS ON: Arduino SPI library.
This library was primarily developed to enable safe wireless programming on Moteino nodes and Moteino based applications such as the SwitchMote. This has been documented at lowpowerlab. Dualoptiboot (all Moteinos come with it) and WirelessProgramming library are required to be able to wirelessly re-flash a remote Moteino.
###Installation
Copy the content of this library in the "Arduino/libraries/SPIFlash" folder.
To find your Arduino folder go to File>Preferences in the Arduino IDE.
See this tutorial on Arduino libraries.
