AVRWARE++ Development Notes 9: Using Atmel Studio to learn C language

    This blog post explains how to learn C language using Atmel Studio. To learn C language programming, we can choose from many development environments, such as TC, VC or Eclipse, etc. If you want to get familiar with the Atmel Studio development environment while learning C language, then this blog post can help you. This blog post introduces how to use Atmel Studio as a C language development and simulation environment, without hardware support. Its purpose is to learn C language programming and get familiar with the Atmel Studio development environment.

    Specific steps are as follows:

    1. Start Atmel Studio, File-New-Project, and a dialog box as shown below will appear. Select the GCC C Executable Project project type and enter the name and path.

    2. After clicking the "OK" button, you will be asked to select the chip type. Here we choose ATmega168PA.

    3. Next, we right-click on the project and select Properties in the pop-up menu.

    4. In the dialog box shown in the figure below, we select Toolchain and set the optimization level to level 0, which means no optimization.

    5. In the dialog box shown in the figure below, we select the simulation type as AVR Simulator, which is software simulation.

    6. After completing the above work, we can enter the program. For example, if we want to solve the sum of 2 numbers, the program is as follows:

    7. We click the "Start Debugging" button to compile and run the program, as shown below:

    8. Then click the "Pause" button to stop the program.

    9. The program is now paused in the while loop. Open the Localc form and we can see the running results, as shown in the figure below.

    In this way, through the above methods, we can verify most of the programs in the current C language textbooks, and further familiarize ourselves with and master the Atmel Studio development environment. Of course, I still recommend that it is best to simulate on hardware. For example, we can first adjust the serial port, and then use the serial port to implement the printf and scanf functions, which is also a very good choice.
