I did clearly state that that's what I "thought" the page was about, not that you had in fact claimed.
I do not doubt your contributions to the community, I was of course mistaken in thinking that all of the project was open source. I have not "distorted" any project that you have done, I do not quite understand where you get that impression from.
I have done quite a bit of research, but maybe I am not searching for the right thing, kind of where a pointer or two would have been appreciated, and I have not got a complete picture, so maybe the information was out there but now is lost or under different search conditions to what I am entering.
My own contributions to the community is freedom of information for topics that various folk are stuck upon for which I spend time researching and helping with, quite a lot of it results in people never coming back with their final solution, but the information is none the less there for others to use as they see fit, I don't claim things are my own if they are not and I also do not make profit from any research that I do for the community forums, unfortunately as I am finding out, you don't always get back what you put in. - Topic: OBD2 QuestionsYou Reply: Stanley,
With respect, I am not asking you to "teach" me, I was merely asking for perhaps some more detailed information or even some resources into where you got your information from to build your own, I do not mind doing the electronics or software myself.
I was referring to freedom of information rather than giving items of possession away, which after all is what open source is all about, which is what I thought the page was referring to.
I am not out to offend or anger you, I am just after some more detailed information to get me started, the simulator was an interesting prospect as it would aid in developing the reader.

I can tell by your responses that you are not exuberant with information or explanation of your device(s), which I can understand to a certain degree, it seems anybody who has remote success with creating an OBD tool is keeping whatever information they have very close to their chest.
The hardware side of things I can get the information from the ELM datasheet, which isn't an issue, I have done quite a bit of reading and searching on the web I have drawn the conclusion that yes the information is available at cost from the SAE people. Unfortunately, like many others, I do not have $$$$'s to spend on documentation for a hobby level project, commercial ones might be different.
For example, there is mention of VPW, PWM at 10.4khz, and then another PWM at 40khz, then there is ISO K + L and KWP2000 (2 Different types I understand?). It seems that if I wanted to use this for other vehicles for members of family I would need to utilise all protocols as I do not know which ones are available as some are different that others pre 2008.
I was hoping to use a piece of Vero type board with a few chips and components on and just build a small display device which has the information on without the need for a "kit" as such, as they are big and bulky and not that easy to hide away.
I presume once you get either a reader or simulator working the interface is the same and the protocol is similar with their own response codes (which I guess are outlined in the expensive documents available to purchase).
I was hoping for a bit more seeing as the things that jump out are "FREE matics and Open Source", but as I say, I can in a way understand the reluctance to open the information.
