Question about USB with standalone

hello guys,

first i would like to know if this USB converter will work fine with arduino standalone ? http://www.ekt2.com/products/productdetails?ProductId=27764c89-6390-496f-b78e-216a638951ba

second, is it possible to connect the TX and RX pins of the Atmega328P to another TX and RX pins of another Atmega328P and in the same time to this USB module ? 4 wires, 2 going to other atmega and 2 going to the usb module

Yes but there is no DTR signal so you will have to time a manual reset when uploading code.

No you can't do that if the USB is sending stuff at the same time.

This one definitely is http://www.mouser.com/ProductDetail/mikroElektronika/MIKROE-483/?qs=%2fha2pyFadugsEwyLV5fFyIWdPbushEDhRSvnBE0ODG8%3d as is this one http://www.tinyosshop.com/index.php?route=product/product&product_id=600

2nd part - no. The FTDI module and the Tx/Rx to other modules would all use the same pins. They would conflict with each other.

You can use software serial to connect other pins to other arduinos.

Or go to a processor with 2 hardware serial ports, the Atmega1284P.

Grumpy_Mike: Yes but there is no DTR signal so you will have to time a manual reset when uploading code.

well i don't need to upload codes to it because i already would have done it before, it's for receiving data through RF links and representing it with processing

CrossRoads: You can use software serial to connect other pins to other arduinos.

ok great i know how to do that, so simply use other pins on ATmega328P to define it as TX RX with software serial library and it will be good to go for representing data on processing or other ?

Yes. Just not as fast as the hardware serial.

ok great thanks a lot :)
