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](https://lowpowerlab.com/shop/product/72) used on [Moteino](https://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 native *SPI library*.




This library was primarily developed to enable **safe** wireless programming on Moteino nodes and Moteino based applications such as the [SwitchMote](https://lowpowerlab.com/guide/switchmote/). This has been documented at [lowpowerlab](https://lowpowerlab.com/guide/moteino/wireless-programming/). [Dualoptiboot](https://github.com/LowPowerLab/DualOptiboot) (all AVR based Moteinos come with it) and [RFM69_OTA WirelessProgramming library](https://github.com/LowPowerLab/RFM69) 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.
