False alarm - sort of. Tried on another computer, and it works there. Must be some issue with my desktop.

Sorry for the noise.

I have an XC-1A that I purchased in 2010. It has served well as a sort of PWM control for scientific experiments. I'm trying to update it, and it now flashes just fine with the xTime composer tools, but the COM port for the device is missing in my Windows Device Manager. Is there some setting I'm mi...

Thanks both for your replies. Segher - your advice was perfect, and the code is running quite well now. Thanks again for your help.

I'm attaching my modified code to this post, in case it might help anyone.

Hi Vector, Thanks for your reply. rxd is not a channel, it is a port. More specifically, it is the UART receive port. I want to listen for any incoming input over the serial connection. Ideally, this would be a simple "wait until RXD port goes to 0", since 1 should be the quiescent state o...

Hi again,

I haven't been able to figure this one out. Any ideas? I am attaching my full source code, in case the snippet wasn't enough before.

Thanks for any input.

Hi everyone, I'm confused over the behavior of a select statement. I have two threads in my program. One listens for input, while the other processes pre-cached settings. My problem with the select statement is that even when there is no input for the listener to consume, the select statement behave...

Have you tried the tutorial exercises included with the XDK? The button project does almost exactly what you're attempting to do.

To start this project, go to File->New->XC Project, and select the XK-1 as your Platform in the drop-down menu.

Hope this helps.

never mind. It was an error in types. I had created the receiving variables in each function as chars. However, when I output a value, it was an integer.

I fixed it by defining char values. Like this:
replace this: with this: works fine now.

Hi guys, I hope I'm getting closer here. Compared to before, I have tried to change the code to cache any settings, rather than transmitting them each time. I'm still hung up, though - when my process thread sends it's "I'm done here" signal over process_ch, I get an 'ET_ILLEGAL_RESOURCE' ...

Hi everyone, People commonly ask for solutions to the tutorial exercises. That seems to be something that should be in the wiki. I started such a page here: http://www.xcore.com/wiki/index.php/Tutorial_Solutions Presently, it has my solutions to the exercises for the XC-1A. I welcome any comments or...
