4.0 out of 5 stars
Excellent for non-beginners, 11 Jun 2013
This is an excellent introduction to the intricacies of the Cortex-M processors. Unfortunately the first downloaded example project using the Keil MDK fails to compile as it is missing four of the eight required source files. People familiar with the Keil MDK and other ARM processors will not worry about this, but converts from the eight bit world like myself may find it frustrating. One star lost then, but still recommended.
