FPGA implementation using rs232

[vicky_svnit]

we hav synthesized our program on vhdl design of UART but unable to check the output by using RS232 via hyperterminal

 

[vsmGuy]

you need a level translator.

Have you used one ?

Dear,
there is a lot of simple programs which u can use to check the UART, u can use it to send data and see the received date.u can search for one of thyem.
mikroc a pic microcontroller compiler has a powerful UART terminal which u can use.
Regards

Hyperterminal worked mostly fine for me. Try to use oscilloscope first of all to test your code on single bytes serialization.

B4 checking on hyperterminal of a host PC, first try to check your functionality of UART within the FPGA And then check the voltage levels at the output of the FPGA by sending rs232 data. It must be 3.3V compatible to detect it on PC. IF not then convert your voltage to 3.3V level.

3.3V compatible to detect it on PC ??

What are you talking about ?

To be PC compatible the swing must atleast be +/-12v!

 

[sachingorkhe]

Yes min. voltage should be 3V.

I just want to tell that confirm that your voltage levels should be gr8er than 3V.

Please refer the file attached for your reference.

Hi,
If you are done with all the stuff told by other friends and still not able to get the response, then check which cable are you using.... "cross" or "straight"??? Find out which one is suitable for your code..
