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.
Detailed description
No detailed description exists yet for this component
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
