ATMEGA32 16PU PDF

To burn a micro controller just the burning Hardware is not enough, it requires software also that would download the program present in a computer or memory device into the micro controller. My circuit is adapted from the website of Pony Programmer. In this state, microcontroller is programmable in either mode Parallel programming or serial programming. The signals transmitted from PC is not in a form that could be accepted directly by the micro controller. Those signals from PC should be made suitable for micro controller.

This also introduces you to different GUIs available for avrdude. But why not AVR Studio 6? Yes, this is a question which even I asked when I heard its name. Have a look at the following video. So here it goes… Embedded C welcomes you! Now that you are aware of the different port operations in AVR , we can move forward to actually code our way right through it!

This version is the successor of the previous AVR Studio 5. You can download it from here. For those who do not want to register in order to download, I am posting the direct download links of the images here. Please report to me if the links are not proper, I will update them in that case. Atmel Studio 6. NET 4. You have been familiar with C I presume. You have been working with normal data types and have been writing codes that run on a computer.

But now, we will be using the same C with some modifications to run our microcontroller MCU. The C used in embedded systems design is called Embedded C. Here, you will come across the same if, for, while, do while, case, switch, etc, but you will be introduced to newer data types actually a modification of the existing ones , newer libraries, newer built-in functions and newer registers! What do we need? The following software will assist you in your work.

You can download them from the links provided. We will discuss them one by one here. Installation Installation of these software is pretty straightforward. You should not face any trouble in it.

During the installation of Atmel Studio 6, it might need to install some other stuffs before the actual installation begins. If you face any trouble in installation, you are free to drop a comment below. It allows chip simulation and in-circuit emulation.

It has easy to use User Interface UI and gives complete overview. It uses same UI for simulation and emulation. It has more than code examples.

Atmel Studio 6 Start Page Then, you will see the following dialog box. Now, you can give any name to it, say MyFirstProject and choose an appropriate location in your hard drive. Check Create directory for solution. Click on OK. The list is huge! Choose your device from this list. We choose ATmega Click OK. Atmel Studio Device Selection Now, you will see the following screen. Note that the basic program structure is already prepared for you.

You simply need to initialize your variables and place your code inside the while 1 loop. You have successfully created your first AVR Project! Now to further proceed with it, we need to write a code, which is discussed in the next part. Feel free to explore the software. We will discuss some of the required components as and when necessary. We will write the code for blinking an LED. The schematic for physical connection is given below. For full schematic, view the circuit diagram of your development board.

Now most of you will copy and paste the code. But I suggest you to type the whole code. This will introduce you to a whole new feature! You can select it and hit enter key. This increases your typing speed also somehow!

Plus it also gives you greater confidence in writing the code. Rest of the code is simple and straightforward. Configuring Atmel Studio 6 There are two things that you must configure in order to make your code run in your MCU in a better way. It will either wait longer or for lesser time. By default, delay. UL stands for unsigned long. Check your development board if any crystal oscillator is present or not across the XTAL pins.

If it is present, note down the exact value of the frequency. We will discuss about fuses later. Note: You must set fuse bits for a new AVR microcontroller. These fuse bits will specify the correct clock frequency whether to follow internal clock or external clock and many other settings. To learn about fuses, view this. Now, how to put? Well, the simplest way is to add the following code before including the header files.

Always check this out before compiling your code. Atmel Studio Clock Optimization Optimizing your Code You need to choose an appropriate optimization level for your code. Choosing the right optimization level will result in smaller hex file and faster compilation time. Atmel Studio Code Optimization To know what optimization is, view this. For more details regarding optimization of code in AVR, visit this page. Building your code After writing the code and configuring it, we proceed to build it.

Now, it builds your GCC C project. After the build process has finished, you will see the details in the Output window below the source code window. There, you can check your memory usage and the build log. In the end, it shows Build Succeeded. If still it shows Build Unsuccessful, then post your queries here, I will look into the matter. Build Output Message Now, once you have built your code, a. You can find it in the following directory For this, we will use avrdude.

So, we will be using avrdude. The interface of Atmel Studio 6 is a lot different than its earlier editions. Also, the AS4 project is not supported by AS6. It is a free software that comes with WinAVR package. To have a detailed idea of how avrdude works and how to run it using command prompt, view this page. Its called FreeISP. The download link is provided at the top.

If an error like Error reading application settings pops up, simply click OK. For the above code, leave it blank. Choose you device and the COM port. Click Program. After you click program, FreeISP invokes avrdude and passes the required comments to it as per your inputs.

Then avrdude reads your device and verifies your device ID and your chip signature. After that, it erases the flash and then writes the new hex file specified by you into the flash. Then it once again reads the flash in order to verify the data. It might have already started to respond to your code… check that the LEDs must be blinking! If programmed correctly, you should see something like this. Thank you. You can find his tutorial here.
