"I've been asking lots of keil questions and no one told me to go to keil forum."

I frequently cite the Keil site - must've just missed you?

"is it ok to post keil questions here?"

If it wasn't, I'm sure you'd know by now!! ;-)

People (including me, I admit) quite often cross-post on both sites; I don't think there's a problem with that, but it's polite to mention in your post that you've done it - and to make sure that you monitor responses on both sites
