Simple UART for FPGA is UART (Universal Asynchronous Receiver & Transmitter) controller for serial communication with an FPGA. The UART controller was implemented using VHDL 93 and is applicable to any FPGA. Simple UART for FPGA requires: 1 start bit, 8 data bits, 1 stop bit! The UART controller was simulated and tested in hardware.
