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

Application written by Giancarlo Bacchio

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
