SPIMemory Formerly known as SPIFlash. Please report any bugs in issues Arduino library for Flash & FRAM Memory Chips (SPI based only) Download the latest stable release from [here](https://github.com/Marzogh/SPIMemory/releases/latest). Please report any bugs in [issues](https://github.com/Marzogh/SPIMemory/issues/new). This Arduino library is for use with flash and FRAM memory chips that communicate using the SPI protocol. In its current form it supports identifying the flash/FRAM chip and its various features; automatic address allocation and management; writing and reading a number of different types of data, ranging from 8-bit to 32-bit (signed and unsigned) values, floats, Strings, arrays of bytes/chars and structs to and from various locations; sector, block and chip erase; and powering down for low power operation.

Refer to footnote£ below. Simblee Sparkfun Simblee - £ ESP32 boards usually have an SPI Flash already attached to their default SS pin, so the user has to explicitly declare the `ChipSelect` pin being used with the constructor Flash memory compatibility - Actually tested with Manufacturer Flash IC Notes Winbond W25Q16BV W25Q64FV W25Q64JV W25Q80BV W25Q256FV Should work with the W25QXXXBV, W25QXXXFV & W25QXXXJV families Microchip SST25VF064C SST26VF016B SST26VF032B SST26VF064B Should work with the SST25 & SST26 families Cypress/Spansion S25FL032P S25FL116K S25FL127S Should work with the S25FL family ON Semiconductor LE25U40CMC AMIC A25L512A0 Micron M25P40 Adesto AT25SF041 Macronix MX25L4005 MX25L4005 Giga devices GD25Q16C (Used on the Adafruit ItsyBitsy M0 Express) Should work with any flash memory that is compatible with the SFDP standard as defined in JESD216B FRAM memory compatibility - Actually tested with Manufacturer Flash IC Notes Cypress/Spansion FM25W256 Should work with the FM25W family Installation Option 1 Open the Arduino IDE.

All previous versions of the library had a FastRead bug that prevent it from doing what it was supposed to. Enhancements: An alternate version of the constructor SPIFlash flash(int8_t *SPIPinsArray); can be used (only with ESP32 boards as of now) to enable the use of custom SPI pins. SPIPinsArray has to be a 4 element array containing the custom SPI pin numbers (as signed integers - int8_t) in the following order - sck, miso, mosi, ss. Refer to the wiki for more information. Resolves #113 Created new error code NOCHIPSELECTDECLARED for errors with declaring custom SPI pins. Using other SPI ports (HSPI, VSPI, SPI1, SPI2 etc.) is now also supported on ESP32 boards - along with SAMD and STM32 boards (supported since v3.0.0). Resolves #177 Formatted and merged pull request #153. This changes the way setClock() works and allows for the definition of clock speed before the SPI Bus is instantiated. Refer to wiki for further details. Thanks @rambo.
