Serial programmer for avr

First I flash the hex file and then after successfully writing the hex file, i separately write the fuse bits. IS my understanding correct Sir. Thanks, vinay. Sir I made the programmmer but while setuping the inferface. SYS is not loaded "" What could be the mistake pls help and thanks in advance.

Does Windows 7 supports pony prog. Can it be made to work on win 7. What should be done to make it work on windows 7. Hi ashin how to set the serial port is shown in the images above.

Sir Its working fine now I got the pins wired incorrectly!! Thanks 4 all the help. Sir I am facing a little problem. I used a 5v regulator to get 5v to the programmers but it reduces to 4. IS this normal and what can we do about it. Hi, I am getting the problem on clicking probe, it says Test failed!! What should be done?

Please help me asap. Thanks 4 all the help u provided with Thank u sir. Since it's a software based USB interface I'm guessing it's speed won't be too high and neither will it be very reliable. Why not develop a usb programmer with a chip that has hardware usb support, like "PIC18F2xxx" series. Hi I am using atmega8, downloaded the firmware, i changed the fuse bits following the steps given in your serial programmer tutorial, fuse bits were written ok but after that when I tried to burn the firmware, an error was displayed that "target didn't answer" Kindly help me.

Hi, this kind of mcu locking porblem arrive only when you have some wrong fuse bits. If the mcu get locked then nothing much you can do. If it is required to burn then lock bit for your hex file then do it otherwise. Leave it like that let me warn you!!!!! So read the device datasheet 's configuration bits setting. Hi I got my mistake,basically I am using Khazama to burn firmwear in atmega8,to set the fuse but I used fuse bit calculator ,there is some difference in rrading the fuse bit in calculator vs khazama,eg:If calculator show chk mark on any bit its mean you have uncheck these bits in khazma,I hope I deliverd.

Respected Sir, Sir do u know how to use touchpad type keypad instead of matrix keypad..? Can i use this programmer under windows Xp? I need help since I m beginner to avrdude in Ubuntu and AVR programming, I plan to make this one What should I select in avrdude that is parameters for -c and -p Please mail me the same Hey gaurav I am 2nd year electronics student and at the initial stage of Robotics.

I have taken up a project to build a line follower. Now to program it I need a programmer. But I dont want to buy it and want to make it on my own. Please Help!!!! I have certain personal queries not related to this blog. Can you give me your Email ID so that I can contact you? I'm krishna krish , firstly thanks for your valuable posts on programming the Micro controller and I design this kit and its works fine..!! Hi Sir! Now, let me come to my problem. I had ordered the same programmer a few months ago, but it worked only twice, after that it is unable to work.

I thought that the problem maybe a fried ATmega8, but to my surprise when I connected it to my circuit that I have made as per the diagram provided actually I am a novice.

But there is a fault that I am facing, firstly, the power status light ie Green LED is not glowing and secondly, the busy flag is shown by green led, and not the red one. Secondly, the error message I am getting at my console on avrdude is "unable to set SCK clock period". I created the one given by you, and after a bit of mind boggling hardwork, I figured out that everything is fine no loose soldering, no wrong connections or anything , but the error that i am getting at Ponyprog console is "device error".

It says that either an unknown device is coonected or no device is connected, and by this I mean the target device. I am also providing the system with 5V regulated external supply, I am now unable to figure out what to do. If you will help me, then I will be very thankful to you. Also tell me how to check the crystal oscillator using most simple multimeter I am feeling that it can be a problem yet I don't know about this, I have just completed my 2nd year and don't even know about mcu, yet I have worked with them as hobbyist that too very little because my programmer broke away , since these are vacation days and I have no access to my college lab.

Thank you very much in advance. Hello sir, I done this circuit. It was showing error "24" I gone through the comments, still I cant program my Atmega I this the microcontroller gets fault.. But I bought it freshly and used only. Is there is any chance that the microcontroller get damage? Can You help Me? THE DB9 used here is female one na..??? Sir, I am having little confusion. I know that the above circuit is working properly, but I have this confusion.

But sir, Zeners are not placed at all the pins, not even at the transmitted pin no. Ok Sir, Once Again Thanks for the Description. Will it work with this? Thanks, Ujjwal Soni. Programmer and the burner both do the same job.

They program the hex file into the mcu. So writing something to these type of memory done by burning some connection in the memory burning doesn't mean you will have fumes and smoke this all done internally in the memory and leaving rest as it is.

So burned connections readed as 0 and non burned connection readed 1. In the case of PROM you can program only once , you can't erase it. But uveprom memory you can program it using burner but to erase them you need uv light. So programmer of these microcontroller is sometimes called burner. But now a days almost all the microcontroller has flash based memory to store the program.

So nothing is burned thats whay it is called programmer more likely. Hi there! I've read all the comments trying to guess a solution, but i couldn't. What can be wrong? I'm running it on a proto board P.

Thanks for your answer. Currently, I'm using a power adapter rated 0. I made a simple circuit using a voltage regulator, but it isn't working apparently -EDIT- I have tried now with another power supply the one with the voltage reg which supplies exactly 5. Hi Gaurav Chaudhary, I just finished the "AVR in-circuit programmer" that you provided, and I am happy about it it took me 2 days to figure out why it wasn't working.

Now everything is fine and I am going to the next level which is your USB programmer. Thank you for your friendling sharing and support. I have used atmega The probe test is OK But when i tried to program it shows Device missing or unknown device Hi Gourav, I am a newbie in this field. I built this programmer as provided in the diagram above. But while trying to program the atmega8 mcu the ponyprog is telling "device missing or unknown device ".

In my circuit the connection to mcu is provided through ic socket. I have a doubt that whether we need to connect crystal to mcu. Please help. Sir can i program Atmega32 using this programmer and what device i should select in Ponyprog as it does not show atmega32? Sir, I am tinkering with micros. But this does not work with windows 8. Guidance from you will be invaluable for me.

Sir I have to program atmega16 for my project. I need to design the burner for it so can you help me with the components and the precautions I should keep in mind. Hey Gaurav, i saw the circuit of the serial avr programmer. I am using ATmega32A for my project, and i tried to read and download my hex file using ponyprog It works and got the successful msg for the first time bu from second time onwards it is showing "Device missing or unknown device " msg Test passed in Poyprog software but while reading the device it is showing the message as "Device missing or unknown device " Tell me how to solve this problem?

But, sometimes your program does not work how you intended to, or you might want to test parts of your program. Going back to our previous example of blinking an LED. If you have a debugger connected to your microcontroller and the software that compliments the debugger, you can execute your code line by line.

You can have breakpoints that allow your debugger stop at specific points in your code depending on certain conditions. The advantage is that not only does it allow you to debug your code, you can still program your microcontroller. So, if you are just a beginner learning the ins and outs of programming your first microcontroller project, you will not require a debugger. An AVR programmer is all you need to get started.

Your initial projects will be basic enough that you will be able to debug your code and circuits by trial and error. As you advance in skill, and project complexity, a debugger will be a great tool to add your arsenal, as you will be able to debug your code and circuits much easily. The software, also commonly referred to as the IDE Integrated Development Environment is what you used to write your code in,compile it to create a.

HEX file and then be able to connect your programmer to your microcontroller in order to program it. When acquiring an IDE, make sure it has the capability of compiling code to create a.

HEX file , and has the ability of talking with your programmer. You can write code, compile it, program your microcontroller and debug it as well. A standalone AVR microcontroller requires a programmer in order to program it programmers like the ones mentioned above. The tell tale sign that an Arduino board has an onboard programmer is that it has a USB port. All you will need to program it is a USB cable. Some Ardunios however, to save cost, do not include an on board programmer.

An Ardunio can be seen as a development board. Except it does not have additional components such as motors, sensors, switches in built. There are other companies that manufacture other types of microcontrollers. The most common of them include the PIC and The process of programming these chips is the same as the AVR write the code, compile it to a. Most of them use ISP as a means of programming the chip as well.

However, because each type of microcontroller has its own hardware platform, companies have developed their own unique programmer for them. So, you can see that the AVR programmer is a crucial element when it comes to the process of programming an AVR microcontroller. It allows you to be able to load your code that you have written onto to the microcontroller to see it in action. AVR programmers perform only one task, that is loading code into a microcontroller.

If you want to test your code line by line while it is running, as well as have the ability to program it, you will need a debugger. Search for:. After writing the program, this program needs to be downloaded onto the microcontroller. What is AVR Programming? What is a Program? The first step of the program is that the user writes their program using a software language. In the next step select "AVR micro" and your microcontroller type that you will be programming ex. At this point PonyProg configuration is complete and we can open hex program with which AVR microcontroller will be flashed.

You should see hex numbers as shown on the screen below. If you haven't connected AVR Programmer dongle to your computer's serial port yet, then now is the time. Click on "Yes" button to confirm the programming.

Now sit tight, relax and watch the programming progress on the status bar. PonyProg will program AVR microcontroller and verify if the hex file was transferred without any errors. For your information this process shouldn't really take more than 10 to 30 seconds.

This depends on the size of the program that you're trying to flash. After programming is completed "Write successful" window will be shown letting you know that AVR microcontroller has been programmed, and is now ready to be used.
