I want to try and get a data link with handshaking going, but as a first start I have 2 Arduino boards, one on my pc and one on my laptop.
I thought that as a beginning I would hook them up Tx to Rx, Rx to Tx plus ground, and just get each returning a message and flashing the LED every second.
But I need the serial ports to program the chips dont I ?
And if I did get it programmed, would I not have problems regaining control via the serial USB using these ports?
I have done some searching but there seems to be no definite guidance ( see http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1147888882
for example )
I will then want to try and connect two radio modules that I bought before the holidays, that are supposed to be like a transparent link, http://www.rfdesign.co.za/Files/5645456/RFOEM%20manual1.5%20Montar%20LH%20pdf.pdf
which is why I want to connect them to pins 0 and 1, the modules have all the preamble, CRC etc built in, so I assume that would confuse virtualwire ?
And I am powering both modules via the usb port for these tests, so the serial link to the pc would still be connected??
Has anyone done something similar and can give advice...?
