UART is a versatile and widely used communication protocol that is suitable for a wide range of applications. Some of the features of UART include: 1.

This will result in increased the speed of UART. Whole design is simulated with Xilinx ISE8.2i software and results are completely consistent with UART protocol.

The tutorial is intended for those rolling their own boards out of an Arduino-based prototype, but it will work in any situation where you need multiple connections to a single set of UART pins.
