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: "When we receive the start of the command, we append all subsequent characters to commandBuffer."

A block of code is set as follows:

data, err := uart.ReadByte()
if err != nil {
      println(err.Error())
}

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

func main() {
      blocker := make(chan bool, 1)
     <-blocker
     println("this gets never printed")
}

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

tinygo flash –target=arduino-nano33 Chapter06/tinygame/main.go

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "The value is pretty stable at 37888."
