SPIFlash Please report any bugs in issues. This Arduino library is for use with Winbond serial flash memory chips. In its current form it supports identifying the flash chip and its various features; automatic address allocation and management; reading and writing bytes/chars/ints/longs/floats/Strings from and to various locations; reading and writing pages of bytes; continous reading/writing of data from/to arrays of bytes/chars; sector, block and chip erase; and powering down for low power operation. For details of the Winbond Flash chips compatible with this library please refer to the Excel spreadsheet in the Extras folder. Compatibility Arduino IDE versions IDE v1.5.x IDE v1.6.0-v1.6.5 IDE v1.6.9 Boards Arduino Uno Arduino Leonardo Arduino Micro Arduino Fio Arduino Mega Arduino Due ESP8266 (On the Arduino IDE) ATTiny85 Installation Option 1 Click on the 'Download zip' below. Unzip the archive and rename resulting folder to 'SPIFlash' Move the folder to your libraries folder (~/sketches/libraries) Option 2 Open the Arduino IDE. Go to Sketch > Include Library > Manage libraries. Search for SPIFlash. Install the latest version. Change log v2.3.1 W25Q256FV support added. (Thanks Stanislav-Povolotsky!) Cleaned up redundant code in TestFlash.ino and SPIFlash.h that was causing confusion. ### v2.3.0 ESP8266 compatibility added Compatible with Arduino Fio and Micro Now compatible with Arduino IDE v1.6.9 Compatible with Arduino-Makefile. (Thanks Raphael!)
