How it works
This project is an edited version of the example CUSTOMISABLE DESIGN - UART from digital design guide. Implements a a UART transmitter using registers made from D-flip flops and multiplexers. The characters QSM are sent continuously.
How to test
To begin transmission:
- Connect CLK signal
- Set IN6 ("Load") to OFF
- Set IN7 ("Output Enable") to ON
- Set IN6 ("Load") to ON
