Hi Mike... yes, I was testing between ground and the GPIO pin question (GPIO1 in my case) for voltage. See my later message I posted for details on what I found. 73 Stephen K1LNX On Thu, Aug 4, 2016 at 9:05 AM, <mike@midnighteng.com> wrote:
Sorry, I do have to ask the obvious, Are you sure you are testing the output correctly ? I believe these FLOAT and switch to ground when active. Just like a parallel port.Don't use them so I don't know for sure. So you need to check continuity between ground and the pin in question for activity.

I'm trying to manipulate a GPIO pin off of a URIx and I am not able to get it to work for whatever reason. If I send a cop,62 command to toggle it, it does not change the state.
I found this message from Jim that was posted in June 2011:

Does anyone know if this was ever implemented? This was quite some time ago.
I might be able to use usbradio instead for my application, but prefer SimpleUSB as it's easier to implement.
