hi all .

The Slack Book hope you find it helpful I did. Then Aliens blog keeps up with the arm and what he has been doing. Alien Bob's arm

You should start by learning to spell first. As you were told before, you need to SPELL OUT YOUR WORDS, and stop using text-speak. It's "please", not "plzzzz".

And since you're someone who (supposedly), has a Masters-degree, and has been working on device driver development and programming since last year, it's surprising you're still needing us to look up books/videos for you, especially given your previous threads where you asked people to look up job openings, and do similar searches. Did you not read those answers?

Did you bother to try putting "how to write programs for the arm processor" into Google??
