+# Arduino IDE ESP8266 - library for SPI Serial SRam 23A1024/23LC1024 by Microchip Technology Inc.
+
+This Library provides the interface for a 1Mbit SRAM chip
+with ESP8266 through SPI connection.
+Microchip 23A1024/23LC1024 - [download datasheet here](http://ww1.microchip.com/downloads/en/DeviceDoc/20005142C.pdf)
+
+Application written by [Giancarlo Bacchio](bacchio.giancarlo@gmail.com)
+
+
+## Getting the code
+
+You can install SRam Library for your ESP8266 downloading the code that is hosted at https://github.com/Gianbacchio/ESP8266_Spiram.
+
+Selecting "Watch" box in the GitHub repository, you will be informed about the latest development updates of this library. 
+
+
+## Installing the code
+
+The downloaded code in *.zip format can be included as a new library into the IDE, selecting the menù:
+
+     Sketch / include Library / Add .Zip library	
+
+
+## Usage
+
+The Hardware connection is done using the standard HSPI interface of the ESP8266.
+
+The chip is connected as per para 3.8 "SPI/SDI and SQI Pin designation" (see datasheet)
+
+Power supply is 3,3Vcc.

+
+## Examples
+
+- ESP_spiram.ino : a basic example to understand how the library works. You can write and read a Byte in a given location of the SRAM
