Async transmitter It creates a signal "TxD" by serializing the data to transmit. Async receiver It takes a signal "RxD" from outside the FPGA and "de-serializes" it for easy use inside the FPGA. This project has five parts How the RS-232 serial interface works * Baud generator * Transmitter * Receiver * Example of use
