Arduino IDE使用的是C++的变量类型,因此它支持C++的所有常见变量类型。以下是在Arduino IDE中常用的C++变量类型: 基本类型 int: 用于表示整数值,通常为16位。 unsigned int: 用于表示无符号整数值,通常为16位。 long: 用于表示长整数值,通常为32位。 unsigned long: 用于表示无符号长整数值,通常为32位。 char: ...

The long data type is used to store large integers. Variables declared as long use four bytes of memory, so they can hold up to 232, or 4,294,967,296 different numbers. But since long variables are signed, that number is split between positive and negative values (-2,147,483,648 to ...
Arduino - Data Types - Data types in C refers to an extensive system used for declaring variables or functions of different types. The type of a variable determines how much space it occupies in the storage and how the bit pattern stored is interpreted.
int(16 bit) - signed number from -32768 to 32767. This is most commonly what you see used for general purpose variables in Arduino example code provided with the IDE unsigned long(32 bit) - unsigned number from 0-4,294,967,295. The most common usage of this is to store the result ...
of a body in any direction while the gyroscope measures rotational velocity or rate of change of the angular position over time, along the X, Y and Z axis. These sensors are used in combination to detect the velocity of an object. A commonly used gyroscope with Arduino is theMPU6050module...
Currently renames all variables to be the width expected in Arduino. Could be used to change any variable type to any other by editing the std::pair at the top of TypeRename.cpp To compile the tool just run: make Then run: ./run_example.sh my_file.cpp It will scan the AST of my...

Below is an example of the NULL value in use. <?php$x=NULL;$y;var_dump($x);var_dump($y);Copy The script above should print out NULL values for both of the variables. NULLNULL Conclusion I hope by now you have a decent understanding of the different data types that are available ...
