I also have good success with those USB to RS232 adapters which is amazing since I've looked at the very ugly waveforms these things produce due to lack of power from their built-in DC-DC converters.
However trying to toggle control pins (such as CTS or DTR) in a non-RS232 way might be a little hit-and-miss with these as some chip sets seem to do this better than others. Then it might be tricky to actually drive much of anything with the signals due to the waveforms described above. At another radio station I work for, I rigged up an "air-check skimmer" audio logger machine out of an old (very old) computer running Linux and triggered it from a parallel port using somebody's program called something like bit pin or something like that that simply allowed to read or set pins on the port. In fact I also used this program for even another radio station where I rigged up a primitive automation system for satellite delivered content using Linux and a GPIO controlled audio switcher that they used for a few months as I was building their "real" radio studio (I wasn't up to speed on Rivendell at that time). Finally, my opinion of Arduino is good until you need to do networking with them at which point I think a Raspberry Pi becomes more cost effective (plus you then get power of Linux!). -----Original Message----- From: Brian McKelvey [mailto:theturtl...@gmail.com] Sent: Wednesday, March 05, 2014 9:44 AM To: Rob Landry Cc: Jim Stewart; rivendell-dev@lists.rivendellaudio.org Subject: Re: [RDD] Documentation on implementing GPIOs? USB-Serial gives you an RS-232 port, but you still have to do something with that port, connect it to something to interface with, for example. Are you saying that you can use some of the RS-232 pins as GPIO directly?
