1.) buy the module suggested

2.) plug the module in to the PIC. Rx of module to TX of PIC and TX if module to Rx of PIC

3.) write program that will use the PIC's UART module to send data, with the correct configuration (baud rate, stop bits, parity, etc.) to be compatible with the USB to TTL module.

4.) use a terminal program (i.e. hyperterminal or TeraTerm) to connect to the virtual COM port that is created for the USB to TTL-again, with the same configuration add both the PIC and USB to TTL module are using and watch the data stream.

Remember post # 18?

​

Try reading. I refuse to repeat myself for the third time!

...see post #18, please actually read what I've written, I wrote that for you to understand what to do, yet you continue to ask the same question, this is now the forth time you've asked this question in this thread alone.

if you need help with configuring the terminal, I've never used RealTerm, so you'll have to consult, another resource: http://realterm.sourceforge.net/index.html#Baud_Rates__Ports

So, why you don't tell me what to do????????????

What do you think I've been doing!?​

 

here is the screen shot.........
the problem is the char are not received back from uC as per code...

Don't let it get to you. Ritesh has proven himself on multiple occasions and on multiple forums that he is incapable of thinking for himself, and also incapable of listening to what other people are trying to tell him.

Honestly, I'm surprised you've stuck with it this long. Your patience level far exceeds my own. Personally, I think he's hopeless.

On the USB to TTL module, connect your TX and RX pins together and type in the terminal window.

When you connect your PIC, make sure you connect the USB to TTL's RX pin to the PIC's TX pin and vice versa...

I am working and don't what is is the problem encountered so, i need help to remove it!!
you can see the screen shot i have changed the baund rate to 9600 and the com port as per display in device manager!!

I know, I responded too hastily.. I tend to read the posts, and walk away so that I don't respond with my initial snide remarks... It's clear when that method fails!

Call me a hopeless romantic, I guess.....

Its cool idea and is is working!!

done this!! but not working!

Okay, so the module is working, at least!

What is your schematic? Perhaps you should turn a LED on when the Program begins to run so you know it is working properly...

Also Ritesh, you do not need exclamation points after every sentence. Please stop--it's making you sound like you're yelling and being very demanding. Unless you intend to sound rude, I suggest you refrain from overusing them.

 

Here is the schematic!!

...and you have both ground and power pins connected together respectively?

You are powering the whole thing from the 5V supply on the USB-to-TTL module, no?

 

...also, once the connections are confirmed, you must press a button while the terminal window is in focus to get something back...

 

...and you have both ground and power pins connected together respectively?

Yes...

yes taking power from usb module.

...also, once the connections are confirmed, you must press a button while the terminal window is in focus to get something back...

Which button i press reset switch on uc board many times

 

Which button i press reset switch on uc board many times

No, no, on your keyboard...in the terminal window...

 

No, no, on your keyboard...in the terminal window...

Yes i do on keyboard also but nothing come back the terminal window show status of
CTS(8)
DCD(1)
DSR(6)
BREAK

and when i type TXD glow but RXD not glow status..?
and i am using stop bit one, hardware flow control to RTS / CTS , parity none and display as ancii

 

The window is also displaying UARt framing error received and break cond received ..
when i press F then reset the unknown symbol show all time like this \

 

try having the PIC transmit only and constantly...

You'd have to check what that means in RealTerm ...

Now what to change in code you tell...

You'd have to check what that means in RealTerm ...

Yes i have searched in Google but i change them manually to see whether it is working or not but nothing happens.

I was thinking to transmit the dta from uc to PC for this will this will work OK??
TXREG = 'a';
