UART Software (Timer) component

Creates a reliable software UART that can be driven using a timer interrupt setup by the user. The timer interrupt must be interrupting at the required baud rate. e.g 9600Hz.

Examples

Simple example showing how to enable a timer interrupt at the desired baud rate then receive a string. If anything is received then it will be echoed back out and displayed on a LCD
