Hi

I'm guessing this is a school project.  (I never had neat projects like this when I was in school).

 

I didn't look at the Actixe-X, but I guess I'd start by making a look-up table where each of the letters would be represented by their Morse code equivalent using dots & dashes.

 

Morse code has a standard timing to it - a dash is three times as log as a dot...etc. On the transmit side, I'd use the PC's sound card to generate a tone based on this look-up table and the timing parameters.

 

On the receive side, I'd plug the speaker out from the other PC into the sound card line in. The program would sit in a loop and wait for the tone, and based on the timing, know when a character was completed, look it up and display it.

HAHA

nah, this is not a school project at all.

 

Actually, i want to communicate between two PCs wirelessly through RF. So , firstly, i wanted to start with something simple.

 

The loop thing can be done but i need to set many parameters too. This is from the transmitter side. What about the Receiver side? Need to set the frequency and all

Somil,

 

Sorry, I missed the wireless part...

 

I'm sure LV has VIs that will look at the sound card for a specific tone & give you a true when it sees it. 

 

But I would think there'd be a way to do it with a wireless router & a couple of wireless NIC cards...

Wireless communication with morse code?Smiley Surprised

 

Maybe we should start a Rube Goldberg thread for hardware.

But why not use something off the shelf like you mentioned?
