How to transfer the data from PC to FPGA Board thru RS-232?

I want to implement UART in FPGA... I want to display the data which I am sending it from my PC... For that I hav to use RS-232 connection...
How to transfer the data from PC to FPGA Board thru RS-232?...

tx/rx to uart converter board

go to opencores.org and download the uart from there. there is also a uart from cmosexod that works great.

or you can download the Picoblaze uart from xilinx. it consists of a separate reciever and transmitter and each takes only 18 or 22 slices in an FPGA

Re: UART

Here is the verilog code for uart receiver, adjust you clock, create bitstream, download to FPGA and enjoy

Hi Friend

How to use UART with Xilinx FPGA

you can use UART core from Xilinx it easy and good work

you can search in Xilinx website or Download from Here.

bye

I wll chk it...

Re: UART

Hi
May be you can some good IPs for UART in

https://www.opencores.org

you can dawload the IP core from above site

good luck!

hi
UART from www.OpenCores.org

Re: UART

the code in www.opencores.org is working

Do you have max232 or something like that between FPGA and PC?

 

[samcheetah]

Re: UART

yes!

usually the development kits that different companies make, have max232 on board

Re: UART

For UART, the most easy is connect the TX, RX and Gnd line btw the PC n the FPGA. Just connect the I/O pins of the FPGA board to the MAX232 converter that attached to the PC.

Re: UART

the max232 only level converter because the volt from the serial between 12 and -12 and the fpga 3.3volt so we use the max232 but it is not satsfy the portocol

for the UART i make it my the blocks of picoplaz and i think it is good

Re: UART

I have already downloaded MiniUART from www.opencores.org. I don't know how to transmit the data from serial port to FPGA and show by 7-segment.
I used FPGA development board with xc2s15-tq144.
I have done with <sevenseg.vhd+sevenseg.ucf>. It was the auto counter (from 00-->99).
Pls help me,
PS: I am studying FPGA only.

hi,
if i'm not mistaken, if your development board has a UART, then find the pinouts of that, and instantiate it in your vhdl design. i believe this must be the procedure. also, is it a custom board which hosts the fpga or is it a development board offered by some company ? coz, if its a development board, u can post the datasheet or the link where the info about the board is there. that might help others figure out the problem
