Overview

The Cortex-M3 can be programmed using either assembler or C. There might be compilers for other languages, but most people will use assembler, C, or a combination of the two in their projects. Because a lot of information on the way to do programming depends on the tool chain and silicon chips you use, this book will not focus on the details of compiling a program or how to download the program to your circuit board. A little bit ...
