In this tutorial, I’ll go through how to use Comments in Atmega32 and Atmel Studio 7 Assembly and C-Language code to remark single-line and multi-line comments in AVR Atmega32 Microcontroller code. Use the simulator to single step through the program, checking the flags and I/O ports after each instruction has been completed.
Video of Comments in Atmega32
Moreover, If you want to perform and understand comments in atmega32. Then, please watch this Video given below
In Atmel Studio, comments will be displayed. There are two categories of remarks. The first is a single line, whereas the second is a multi-line.
The two sorts of single-line comments are further divided.
Let’s continue to explain the idea using a program.
LDI R16, 0X78 LDI R17, 0X0F ADD R16, R17 ADD R17, R16 Break,
Now, we will run the program by clicking an F7 key. Our program is successfully built.
Now, debug the program.
The processor status must be checked after that. Use the F10 key to step-by-step verify the status.
You can see in the figure below that the general-purpose register R16 has a value of 78.
Furthermore, we will step over to check the status of R17, which is shown below.
For beginners or novice users, it is difficult to understand the code directly, so we will use comments for them to make them understand easily.
Single-line Comment
// is the first kind of single-line comment.
Comments are only written to aid in code comprehension; they are not carried out during programming execution.
We’ll look at R16’s value and make comments on additional code segments. The graphic shows that R16 is filled with value but R17 is left unchanged.
A semicolon “;” is used to indicate the second type of single-line comment.
Following that is considered a comment. The figure below shows that R16 is loaded with a value but R17 is left empty due to the comment.
Multi-line comment
Multi-line comments are the second kind of comment. Comments of this nature are written in brackets /* */. Opening and shutting are essential.
The result is shown in below image.
Why do we use Comments in Atmega32?
We don’t really need comments for short lines of code, but we do need them for longer lines, so we won’t forget our coding notion when we later encounter it. We separate our programs and use comments to clarify the functionality when we add loops to them.
as an illustration I hope you have understood the working of Comments in Atmega32 using ATMEL STUDIO 7 Assembly. Additionally, If you want to see the project Automatic Car Parking System in Atmega32 then visit our website. Further, If you have any queries, you can comment below. Thanks
