Hi, All
I want to use UART to do the transmission between Matlab and FPGA board. I found one from others. I made a simple test to realize transmit data to uart and transmit back to matlab. I will write some parts codes of my test here to make sure you know what I am doing.
entity uart-top is port( sys_clock : in std_logic; PB_LEFT : in std_logic; RS232_RTS_IN : IN std_logic; RS232_RX_DATA : IN std_logic; RS232_CTS_OUT : OUT std_logic; RS232_TX_DATA : OUT std_logic ); end uart-top; COMPONENT uart115200 PORT( SYSCLK : IN std_logic; RS232_RTS_IN : IN std_logic; RS232_RX_DATA : IN std_logic; RESET : IN std_logic; READ : IN std_logic; WRITE : IN std_logic; DATAOUT : IN std_logic_vector(7 downto 0); RS232_CTS_OUT : OUT std_logic; RS232_TX_DATA : OUT std_logic; DATAIN : OUT std_logic_vector(7 downto 0); RXRDY : OUT std_logic; TXRDY : OUT std_logic; parityerr : OUT std_logic; framingerr : OUT std_logic ); END COMPONENT;
