Send serial data from A device to B through AVR

[Dada Krauter]

Hello everyone,

I want to connect two devices to one FT232RL(A device: AVR | B device: xBee).

I want to make two modes:
First: Debug mode > PC communicates only with AVR.
Second: Configure mode > X-CTU program configures xBee through AVR (It sends data to AVR, AVR sends to xBee, xBee sends data back to AVR and than AVR sends back to FT232RL, PC)

Im working with Atmel Studio 6 C code;

See my attachment for detailed schematic>>>

Thanks

That should be entirely possible.
What is your question?

Thank you Harald Kapp for your fast reply

So I want to write this function in C language. Only one part, where AVR sends to xBee received data from FT232RL and where AVR sends data back to FT232RL received from xBee.
Im making flight controller, I have onboard xBee module and I want to configure xBee module by connecting controller to PC without any other FTDI boards like that> https://www.sparkfun.com/products/11812 <(X-CTU>xBee config. program> http://www.digi.com/products/wireless-wired-embedded-solutions/zigbee-rf-modules/xctu <) and also I don't want to use two FT232RL chips, one for debugging and one for xBee config. So I need a simple C code... That will written to AVR.
Again>AVRs function:

PC>FT232RL>AVR>xBee
PC<FT232RL<AVR<xBee

AVR gives direction to serial data, receives from FTDI and sends to xBee or receives from xBee and sends to FTDI(PC)
For debugging mode AVR will not send serial data to xBee.

Thanks again

AND can you tell me how to convert data[] to result? I have following code:

i=0;
while(data(i)!=',')
{
uartprint(data(i)); I can't write this [] so used that ()
i++;
}

the code prints separately each digit. e.g. prints 1 then 2 then 3 (123)

so i want to save each digit together to one integer, let's say to result.

how can I do it in C code?

Thanks again

Not my domain. Someone else come to the rescue?

 

[Dada Krauter]

What about first question? Harald Kapp

Thanks

Someone knows how to do that?? I need C code

Thanks )
