please, i want to know really how to make a communication protocol ( books, links, simples examples)
Because that i know the methodology but i can't make really
Thanks...
You can read about some protocols here
a communication protocol is not trivial but also not undoable
a master thesis PDF describing more than you ever want to know
excuses for the length of the URL
ok... thanks

How did you find that Thesis? Someone worked really hard, I hope He achieved his Masters.
When he started describing the algebraic notation, It reminded me of Discrete Mathematics. And that was a bad memory! :o
Chuck.
How did you find that Thesis?
writing a query for google with use of + (to force that word in the search results, G has more tricks)
in short: Google +design +communication +protocol
Then I copied the URL from search list and cleaned it up. (clicking it would start download PDF)
A long time ago i was making my own protocol. It should be simple, easy and fast.
after few weeks of work i had succeed.
It was very simple, the main thing is that you need to realize what you really need, addressing, data checking and etc.
in my case i was grouping a package from parts that I needed, from other side i was verifying data that i received.
so a quick example: I had a "Start Byte" + "address byte" + "data type bite" + "value" + "data type byte" + "value" ...... "data end byte" + "2 check sum bites" + "end of package byte"
So after my controllers receive the "Start Byte", I compared the address, if it matched my number i read the data types and values, and compared them with my check sum.
very easy and simple.
btw it is a good thing to have a digital oscilloscope so you can connect your bus and see what is exactly going on on low level.
