Perhaps video tutorials or training recordings? To begin with, I am looking at https://developer.arm.com/tools-and-software/embedded/arm-compiler/documentation
I have basic knowledge of C and I have also installed DS-5.
There are a number of coding examples provided with DS-5 (or the new Arm Development Studio). Within the IDE, go to File -> Import, and use the text filter to search for Examples.
Thanks, Ronan.
