  • What is a "uart usb port" ?

    To get keyboard input via a UART, you will obviously need a keyboard that provides a UART-compatible output!

    To get keyboard input via a USB port, you will need a USB keyboard, a USB Host port, and appropriate USB Host software. If the particular Cortex-M3 chip that you have in mind has a USB Host port, then the supplier will most likely have provided examples...

    In either case, the receiving is independent of what you do next with the data.

    Similarly, displaying data on an LCD is independent of where the data came from!
