Callback function is a function that runs independently of the main
program routine and is automatically executed at fixed intervals. Therefore,
a callback function cannot include code that requires much time. Use
of loops, variables, and function calls are limited.
Usage
- The callback function cannot exist inside another function or program
body.
- There can be only one callback function.
- A callback function does not have a name and cannot be called.
Example
- This example shows how periodically receive wireless data and to
save it in a variable.
