Dear all,

I am new to the PIC uC and have just written a code for the USART function. I am using UM232r [USB module] to communicate with PC.


{ USB module:http://www.ftdichip.com/Documents/Da.../DS_UM232R.pdf

I am using page-14 settings of the USB}

Using serial cable connection, the same code works absolutely fine. As soon as I am using the USB module, it doesn't seem to work at all. That means my code is alright and there might be some error in the USB settings.

The TX section of the code [when using without the RX part] is working fine with the USB though but it's not working for the RX section. In my UM232R USB circuit, I have connected the handshaking pins [RTS# and CTS#] to each other and not to the PIC. It works for the TX part. I am not sure whether this is causing the problem when I am receiving the data.

I will be really grateful if you could have a look it.

Many many thanks.

Ps: I am using TERMINAL on PC for this task.
