Embedded systems programming: Getting started

The next lesson shows how the ARM Cortex-M processor executes code, how it manipulates registers, and how a computer can "do" things in the real world, such as turn on and off an LED.

This deeper understanding will allow the user to use the C language more efficiently and with greater confidence. The user will gain understanding not just what your program does, but also how the C statements translate to machine instructions and get a sense for how fast the processor can execute them. Also, the user will get some familiarity with the ARM Cortex-M core.
