My FPGA is having serial interface Rs-232. I have to use a hyperterminal and send a character to FPGA and FPGA will send same character to hyperterminal. I just need a source code of verilog for that. Can anyone help me abt that.
 

Re: serial iterface

Can you tell us about the UART side. Where your UART will take the data from to send it to hyper terminal? I mean one side your UART will be communicating with the PC through serial port . what about side of UART??

Thanks,
 

Re: serial iterface

the data is coming in through the connector pins on the fpga board.. am connecting a gps module to the fpga board through those pins
 

Re: serial iterface

Here you'll find a reference design from Xilinx to implement a UART in Verilog.
Although it's written for a CPLD it's perhaps useful to you:

Re: serial iterface

i av tried the code frm xilinx n its not working, is there n e other code available?
 

Re: serial iterface

Hi,
If you are using a GPS module to receive GPS data, the out put of such modules is generally through a built in uart of the module. so you will need to design two uarts. One UART will receive data serially from the GPS module and the other one will send this data to the PC hyper terminal. The two UARTs will communicate with each other via a fifo inside the FPGA. I hope you got the idea and will help you in implementing the design.
Good Luck!!
