Pulsin

Hello,
I have created a circuit with an IR detector module and an rs232 module using the sx tech board. I know each module works but I was not sure if my code is correct. Can someone advise me if this is correct? I cannot see anything on hyperterminal or a VB program that I created.

Curtis,

First verify that you can send data to the PC via RS-232 from the SX board. To do this, write a program that does something simple like send the letter "A" over and over. Once you know that is working, then you can concentrate on the IR part. Don't try and solve two problems simultaneously.

Thanks, PeterM
