I have seen Bean's post in the Projects forum and I only partially understand the program. I have no clue at this time how I would control a high current LED." So the "lurking helpers" in this forum must have gotten the impression that the best way "bootstrapping" you would be to provide you with some fundamental information on PWM. Well, now I speak for myself but I think, I speak for others too: I make my living on SX projects and other stuff. Reading and answering questions on the forum requires time that I can't use for any money-generating work - I don't get paid for my forum activities, and I don't want to get paid for it. Supporting the SX and its users is important to keep it (them?) viable, and this is what I want to support. Therefore, it is only natural that forum members helping others try to do this most effectively with a minimum of time. Taking the PWM example - why should Peter write a long essay (thus re-inventing the wheel) about PWM basics when well-suited information about this topic is publicly available elsewhere, like at Google. You say that you use Google every day to search a lot different subjects including PWM, so I'm pretty sure you came across the article at [url]http://www.netrino.com/Publications/Glossary/PWM.html[/url] and others. In your last post, you say: "Really now. Is there anything wrong with asking for a recommendation for reference material?" My answer is "nope", there is nothing wrong at all but a good recommendation can also be the tip to "Google" for such material when it is obviously available there, like in this case. Having said that, let's all calm down a bit - this is a technical, and not an emotional forum! Chris, if you have any problems understanding PWM after having read the docs available via Google, please feel free at any time to post detailed questions here (more detailed than "I have no clue"). You can be sure, there will be valuable answers - the same is true when it comes to implementing PWM on an SX and driving high-current LEDs (I think that was your project). I've done some SX PWM projects driving DC motors consuming up to 15 Amps @ 24 Volts - this is definitely more than a high-power LED "eats" :-) . ---------- End of Message ---------- You can view the post on-line at: http://forums.parallax.com/forums/default.aspx?f=7&p=1&m=79055#m79350 Need assistance?
