of Phil Stewart's [SpiRAM library](http://playground.arduino.cc/Main/SpiRAM)

Hardware:
---------
- A [Stellaris Launchpad](http://www.energia.nu/Guide_StellarisLaunchPad.html) _or_ ESP8266 board, e.g., [WeMOS](https://www.wemos.cc/en/latest/d1/d1_mini.html), _or_ ESP32-based board, e.g., [Node32s](https://www.esp32.com/viewtopic.php?t=459),
- An SD drive to store programs (for Stellarpad),
- A 23k256 SPI RAM chip (for Stellarpad, optional),
- A supported TFT screen, such as [this one](http://forum.stellarisiti.com/topic/626-ssd1289-32-320x240-tft-16bit-parallel-interface-touch-libraries/),
