Conventions used
There are a number of text conventions used throughout this book.
Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: “The payload[length] = '\0'; line adds a null character (0) at the end of the payload data to indicate the end of the string.”
A block of code is set as follows:
const byte led_gpio = 32;
void setup() {
pinMode(led_gpio, OUTPUT);
} Any command-line input or output is written as follows:
$ git config –global user.name "{firstname} {lastname}" Bold: Indicates a new term, an important word, or words that you see on screen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “You should see the Status change to Connected. Click on the Raw data tab; you can see the data with the latest data model uploaded from the device.”
