I have tested it and it works very well. The current 1.2.1 BBB code does not support board level GPIO in software. While this may be corrected in future code I think this method of doing GPIO certainly needs to be considered. I find it a much cleaner way to control I/O. Rather than running a multitude of wires from the BBB itself you just run one USB cable to a distant box where I/O is controlled. It also has the advantage of being usable on any platform - Windows, Mac, Linux. and easily moved between systems.<br><br><a href="http://crompton.com/hamradio/USBtoGPIO/" target="_blank"><a href="http://crompton.com/hamradio/USBtoGPIO/" target="_blank">http://crompton.com/hamradio/USBtoGPIO/</a></a><br><br>A link to this page has been included on the hamvoiip.org site.<br><br>This all became possible with the recent release of a new FTDI multifunction USB chip that supports serial, SPI, IC2, and GPIO.</font><br><br><b><font style="font-size:16pt;" size="4">73 Doug</font><font style="font-size:16pt;" size="4"><br></font><font style="font-size:16pt;" size="4">WA3DSP</font><font style="font-size:16pt;" size="4"><br></font><font style="font-size:16pt;" size="4">http://www.crompton.com/hamradio</font></b><font style="font-size:16pt;" size="4"><br></font> </div></body>
