Use C language to expand the lua module (Entry level) and lua Module
In lua, modules are often loaded to implement some functions. If there is no ready-made module for require, we have to write the module by ourselves.
A few days ago, I used C to extend the sha1 Algorithm Module to lua. Extract and take notes.

the method we bind to it, we have achieved the expected results.
It is not difficult to understand, so we will explain the three stages of message generation, sending and processing.
As we provide an entry-level explanation, I will give you a brief introduction.

Entry-level use of μC/OS-II event flag
Imagine the following: There are three events A, B, and C. When A and B meet A certain condition (or execute an action) then C can be run (continue or run once and then run again after the and B conditions are met ).
If you need to implement this function, you can use the Event Id

1. All the numbers in the program are stored in binary form in the computer's memory . Bitwise arithmetic is the direct operation of an integer in memory bits. 2. And operation: only the first and the two operands are 1 and the result is 1. 3. Or operation: 1 bits are 1, and the result is 1.4. XOR: Not the same is 1.5. Take the inverse operation: Change 1 to 0 and 0 to 1.6. Shift operation: Shift left is multiply by 2, and right moves except 2. Discard if the boundary is exceeded.Speaking
