in technology and computing, a reference is an address indicating where a specific piece of data is stored in memory. when you create a variable in programming, it can either hold a value directly or it can hold a reference to a location where the value is stored. does a reference in ...
readable names for objects and functions, rather than using camelCase or other syntax. For example, instead of "getNumber", a variable could be named "_getNumber" to emphasize its purpose as a retrieval function. It is also used in computer filepaths as a separator between two words or ph...

The message array stores the message that is sent through the UART. The periodElapsed variable is used to control the application flow based on timer interruptions. Add the function’s prototypes for each custom callback (one for the UART and another for the timer). You can select any name...
Tracepoints allow you to log information to the Output window under configurable conditions without modifying or stopping your code. For more information, seeUse tracepoints in the Visual Studio debugger. How do I know when the value of my variable changes?For C++, set adata breakpoint....
reports the size of the data written to the output buffer. In this case of reading a simple DWORD, the size of data is always 4 bytes, that is, sizeof(DWORD). However, this size parameter is more important for variable-size values such as strings; I’ll discuss that later in this ...
