Hello,

I am creating a simple project to control a motor and I have setup some test pins for diagnosis. 

After working with this project for the past couple months all of a sudden this error shows up:

No input on Instance "MyComponent", terminal "Terminal_1".

Terminal "Terminal_1" requires connection when it is visible.

For specificity, I have included an image of my project and where the issue is.

I have tried to find the options that were mentioned here:

https://community.cypress.com/thread/10027?q=No%20input%20on%20Instance%20%22MyComponent%22,%20termi...

but I couldn't find the options mentioned in the link anywhere.

I am currently using PSoc Creator 4.2.

Any help in this matter would be much appreciated.

Thank you.

DeSi,

Sometimes on some convoluted projects Creator shows errors, seemingly out of nowhere. In such case:

1. close Creator

2. Open project folder and delete the fitter file *.cyfit

3. Delete folder Generated_source

This cleans up leftovers and usually works

DeSi,

Hi.  What PSoC variety are you using?   Is it a PSoC5LP?

From your TopDesign snip, it would look like the connection to Tpin2 is connected yet it is complaining.

I've tried to replicate your error under multiple scenarios.   I have no issues in the Application Build phase.

The reason I ask about the PSoC variety your using is that the PSoC5LP uses port 15[6] and 15[7] for USB comm.  It also can use it for expanded SWD (Single-Wire Debug) features.

PS: It doesn't look like you are using any custom components.  So I don't think the one link applies.

Hi Len,

I am currently using a PSoC5LP.

Interesting thing is that I shutdown Psoc Creator and restarted it again, and the issue went away.

it was very weird.

DeSi,

Yes.  Weird.

I'm glad you've resolved your problem.

Thanks, but I am concerned that this temporarily resolves my issue.

I am unsure what to do if this comes up again in the future.

DeSi,

I understand.   However without a means to save the project in that state it can't be reproduced easily by others.
