Having problem to understand how to improve a question I posted

Question

I just posted a question on EE. I am not used to this peculiar SE guidelines, where could I found it if any.

I have received few comments from an user that I do not completely understand. I also found myself a bit uncomfortable about the path he used.

What should I do in order to improve my question. Is it just about the page citation? Or is there something else to improve that I have missed?

Thank you,

Update

Having the above user commenting again:

Page 81 does not have the schematic you eventually embedded in your question. That appears to be on another page entirely. I downvoted you because your incompetence wasted time and you argued about it and you didn't fix your question. Your question is still not fixed. This isn't rocket science, it's plain common sense.

I post what I do see in one of my PDF reader:

Other PDF readers also agreed. From this now I can understand that it is not my question which has a problem. And I do feel very unconformable about the words he is having with me.

Update 2

Having time to chill out about this meta, I just want you to add some inputs:

• All users are not native speakers, and this can be a great challenge at some point, for this kind of fora. I am part of it, English is not my mother tongue;
• Sometimes you do not understand why someone does not understand what you are talking about. It just happens, like it happened with this Q&A. I think the reason why is mainly because we do think in different ways, and this is also a great challenge not an incompetence. The inefficiency is to stick to the problem and miss all possible solutions. I am glad, because I have understood where the misunderstanding resided;
• There are users when they browse a 300 pages PDF that let them go to ease of a search bar or page indexing instead of looking for footpage numbers (that's what led to this misunderstanding, I have learnt from it). Personally, I do read huge books and PDF and I manage them differently. I used PDF page index because I thought it was easier, I just skipped (it literally goes out of my mind) the footpage number, but I did mention the section number, as I ever do when I want to keep a reference;
• I don't think my reference was that incomplete (now updated to comply both footpage number and page indexing). I had also first linked the section number because I knew, as scientist, that references are important. Section tree may have led some user to find the page I was talking about. So I do not feel incompetent about this peculiar reference. What I felt was misunderstanding and some ardor or zeal from another user. Anyway, the most important is the quality of the information, not how it arose. Now fixed, we can go forward;
• Clearly, people do have different standards, they also do have different habits, manners and ways to behave;
• Finally, politeness and humility are good qualities. We should never lose them. I should not have used the word binary in this context, but I did. I apology for that.

Answer 1

Here is what I think was missing in the question:

• The inclusion of the contents of page 81, instead of just a reference (now fixed)
• A few words of explanation on what is a "Adam 4055 module". You provided the link, which is good, but it isn't enough. Just like the missing contents of page 81, you need to explain, with just a few words, what this thing is, so we know the context without having to follow links.

Basically, you need to explain within the question itself (not through links), the general context of the question. You can assume that people know what a resistor is, what a microcontroller is, etc..., but you can't assume we know what a "Adam 4055 module" is. And give this information at once, because if we need to follow links, people will consider the question isn't complete. The principle is that every question should be self-sufficient. Providing links is good (and if you don't provide datasheet links, sometimes, people will get upset too), but enough explicit information within the question text itself is essential. Same for acronyms (some people ask questions with lots of acronyms). Except for a few, like "MCU", you need to be explicit, because they may have multiple meanings, and it can quickly get ambiguous.

For more information, here are the things you generally need to take care of, when asking a question: Electrical Engineering Question Checklist

But overall, the question isn't that bad. What is good about it, for example, is the fact that you explained what you think the solution is, and clearly explained the difference between your setup and the example setup given within the product documentation.

So, even if it is a basic question, I don't consider it a bad one, and I wouldn't downvote that myself, even in its original state (but different people have different standards).

So, don't focus on a single downvote. It may even be reverted by an upvote...
