Conventions

In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "Type cd rrb2-1.1—this will change the directory to the location of the files."

A block of code is set as follows:

void loop()
{
  int dt;
  uint8_t logOutput=0;
  debug_counter++;
  timer_value = micros();

Any command-line input or output is written as follows:

volatile int viRobsapienCmd = -1; // A robosapien command sent over the UART request
// Some but not all RS commands are defined
#define RSTurnRight 0x80
#define RSRightArmUp 0x81

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "Now click on Connect on Remote Desktop Viewer."
