Connect an SPI TFT with Touchscreen to your Arduino - Cheap ILI9341 LCD module

You can get buy some really cheap LCD and touchscreen modules from places like eBay. They're actually great devices that let you add a display to your Arduino and microcontroller projects for under £10. But they don't come with any documentation so they can be a bit tricky to get working if you've never used them before.

In this video I'll walk you through the connections and software needed to get them working. My screen is a generic, red, Chinese sourced device using the very common combination of an ILI9341 based LCD module with a touchscreen driven by the XPT2046 touch controller.

Make sure you visit the project pages on my website for circuit diagrams and breadboard layouts, along with more information and details.
