Overview
********

Every half-second, this sample application draws a color-filled rectangle in a
corner of the LCD display.  The rectangle fill color cycles through red, green,
and blue on each update.

Requirements
************

- `ST NUCLEO-L476RG development board`_
- `Adafruit 2.2 inch TFT Display`_

Wiring
******

The NUCLEO-L476RG should be connected as follows to the Adafruit TFT display.
