Go to the official website of CodeVisionAVR: http://hpinfotech.ro/cvavr-download.html [^1^]
Select the version of CodeVisionAVR that suits your needs: Advanced, Standard, or Evaluation. The Advanced version includes support for graphic displays, the LCD Vision font and image editor, and an enhanced CodeWizardAVR. The Standard version has all
the features of CodeVisionAVR except support for graphic displays. The Evaluation version is free but has some limitations in code size and optimization.
Click on the blue button to add the product to your cart. You will need to create an account and pay for the product if you choose the Advanced or Standard version. The Evaluation version does not require payment.
After completing the purchase process, you will receive an email with a download link and a license key. Click on the link to download the installer file.
If you want to use CodeVisionAVR as an extension for Microchip Studio 7, make sure you have Microchip Studio 7 already installed on your computer. If not, you can download it from https://www.microchip.com/en-us/development-tools-tools-and-software/

Unzip the downloaded file in a temporary directory and launch the CodeVisionAVR installer. Follow the instructions on the screen to install CodeVisionAVR on your computer.
When prompted, enter your license key to activate CodeVisionAVR.
If you want to use CodeVisionAVR as an extension for Microchip Studio 7, you will need to enable it from the Microchip Studio's menu: Tools|Extensions and Updates|Installed|CodeVisionAVR C Compiler|Enable.
You can now start using CodeVisionAVR for your AVR projects. You can access the CodeVisionAVR features from the Microchip Studio's menu: Tools|CodeVisionAVR or from the toolbar icons.

How to Write a Simple Program in CodeVisionAVR
One of the features of CodeVisionAVR is the CodeWizardAVR, which is a tool that can generate C code for various AVR peripherals and functions. You can use the CodeWizardAVR to create a simple program that blinks an LED connected to PORTB.0 of the
ATmega8515 microcontroller.

To use the CodeWizardAVR, follow these steps:


After creating a new project as described in the previous section, select the "Chip" tab in the CodeWizardAVR dialog window. Choose "ATmega8515" from the drop-down list and click on "OK".
Select the "Main" tab and check the box for "Enable generation of the main() function". You can also change the name of the project and the output file in this tab.
Select the "I/O Ports" tab and check the box for "Enable generation of I/O Ports configuration". Then, select "PORTB" from the list and set its direction to "Output".
Select the "Timers" tab and check the box for "Enable generation of Timers configuration". Then, select "Timer0" from the list and set its mode to "Normal". You can also adjust the prescaler and overflow interrupt settings according to your desired
blinking frequency.
Select the "Interrupts" tab and check the box for "Enable generation of Interrupts configuration". Then, check the box for "TIMER0_OVF_vect" and write some code to toggle PORTB.0 inside the interrupt service routine. For example:

PORTB ^= (1
Click on "Generate" to create the C code based on your settings. You can view and edit the code in the CodeVisionAVR IDE.


How to Compile and Upload the Program to the AVR Chip
After writing or generating your C code, you can compile it and upload it to the AVR chip using CodeVisionAVR. To do this, follow these steps:


Click on "Project→Make" or press F9 to compile your code. If there are no errors or warnings, you will see a message saying "Project built successfully".
Click on "Project→Program Chip→Program Flash" or press F10 to upload your code to the AVR chip. Make sure your STK500 starter kit is connected and powered on, and that you have configured the programmer settings as described in section 2. You
will see a message saying "Flash programmed successfully".
You can now observe the LED connected to PORTB.0 blinking according to your program.


How to Debug Your Program Using AVR Studio
If you want to debug your program using AVR Studio, you can do so by invoking it from within CodeVisionAVR. To do this, follow these steps:




Click on "Project→Debug→Start Debugger" or press F11 to launch AVR Studio with your project loaded.
In AVR Studio, you can use various debugging tools such as breakpoints, watch variables, memory views, etc. You will need an AVR ICE debugger connected to your STK500 starter kit to perform debugging.
When you are done debugging, you can exit AVR Studio and return to CodeVisionAVR.
