It isn't true that you don't get help.

Have you, by the way, followed up your delay loop after the comments by Erik? You did pick up on my original comments about delay loop but really did not modify the function into a real timer-based delay. Far from it - your delay do not take into account what the timer does, so it's impossible to believe that it does control the timing by the timer ticking.

You posted a big lump of code just like that asking us to look for errors.

Both me and Andy asked what you had done to check what works and what doesn't work. Zero response from you. We have no idea if you have turned on an oscilloscope yet and verified that all pins are toggling and that the timing seems reasonable.

You might not have realized it, but you control if a thread is on topic or not. If you stay focused and show a big interest in the thread. Give good information about what you have done. Respond to questions etc. Then the other people will see that you are someone who are spending time on this problem and are willing to learn. So people will spend time helping you.

If you post something similar to "help me find error" but don't indicate that it is a collaboration but that it really is "find error instead of me", then the thread will wander in other directions. It's really your choice. Checking "off-topic" or "not useful" is not the way to enforce private tutoring. Only by showing interest, will you make yourself interesting to help.
