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 class=""><br class=""><a href="http://crompton.com/hamradio/USBtoGPIO/" target="_blank" class=""></a><a href="http://crompton.com/hamradio/USBtoGPIO/" target="_blank" class="">http://crompton.com/hamradio/USBtoGPIO/</a><br class=""><br class="">A link to this page has been included on the<span class="Apple-converted-space"> </span><a href="http://hamvoiip.org/" class="">hamvoiip.org</a><span class="Apple-converted-space"> </span>site.<br class=""><br class="">This all became possible with the recent release of a new FTDI multifunction USB chip that supports serial, SPI, IC2, and GPIO.</font><br class=""><br class=""><b class=""><font size="4" style="font-size: 16pt;" class="">73 Doug</font><font size="4" style="font-size: 16pt;" class=""><br class=""></font><font size="4" style="font-size: 16pt;" class="">WA3DSP</font><font size="4" style="font-size: 16pt;" class=""><br class=""></font><font size="4" style="font-size: 16pt;" class=""><a href="http://www.crompton.com/hamradio" class="">http://www.crompton.com/hamradio</a></font></b><font size="4" style="font-size: 16pt;" class=""><br class=""></font></div><span style="font-family: Calibri; font-size: 16px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px; float: none; display: inline !important;" class="">_______________________________________________</span><br style="font-family: Calibri; font-size: 16px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px;" class=""></div></blockquote></div><br class=""></div></body></html>
