Also, you might find that you will get more responses on your work if you put the time into writing better code. As an example, your first function is a single case, switch statement. You do not write a single case, switch statement. That is just an "if" statement.

However, I will endeavor to help you out. I noticed you haven't received a lot of help on the your other posts on this subject.

Where is tcs_on_count defined? It needs to be global static.

You are correct that using PPI/GPIOTE is the only way to effectively handle microsecond timing of GPIO. What I see wrong in your code is that you seem to be handling the events in interrupt handlers.

What exactly is the purpose of the microsecond timing? What function is it providing in your code?

This question is a real mess. Try reformatting your question so the code is actually readable.
