Programming ATmega328p Using USB to TTL

[@monahanz]

Only one that worked for me! Tried several videos before this one. Great work thanks John

[@BasselTech]

Thank you sir! I am glad you finally figured out a solution. Have a great day! :-)

[@puspamadak]

Thanks a lot. Besides the practical demonstration, you also explained the proper connections. With this help, I got my Atmega328p chip to work.

[@demetriosdemetriou1114]

REALLY YOU ARE THE BEST OF ALL PROGRAMMERS, AFTER ONE WEEK GETTING TIRED I HAVE SUCCEED TO PROGRAM THE AT 328 FORM THE FIRST TIME, NICE WEBSITE TOO GOD BLESS YOU

[@BasselTech]

Thank you sir, I'm really glad you found a solution. Stay tuned for more. Have a great day! :-)

[@muhammadafzalkhanqureshi3735]

agree

[@JasonRobards2]

2020, thanks John. Arduino said to use a 0.1µF, but your 10µF did the trick. Here, have some algorithm pleasing engagement.

[@lethong8820]

2019, great work, thanks John. I was so frustrated before watching this video

[@BasselTech]

Thank you! Stay tuned for more! :-)

[@demetriosdemetriou1114]

YES REALLY YOU ARE THE BEST OF ALL WHY? TO PROGRAM AND SETUP YOUR VIDEO IT WORKED FROM THE FIRST NO PROBLEM. ONE WEEK NOW I AM TRYING THE OTHERS FOR A WEEK TO PROGRAM THE ATTINY 2313 AND STILL I HAVE FUTURE TO SUCCEED. GOD BLESS YOU

[@BasselTech]

Thank you sir, I really do appreciate your nice words, and this is what gives me motivation to do more tutorials. If you have any question at anytime please feel free to comment on any of my videos or contact me at my email: [e-mail] Thank you so much! Have a nice day! :-)

Good One. Very Good. Thank you for not playing horrible background music like others

[@GeoffLord]

Great tutorial, i hope you make more, that was really educational and has taken my knowledge to another level... Thank you.

[@BasselTech]

Thank you, Geoff! I'm glad you enjoyed it! :-)

I am interested in learning some concepts to integrate IC programming function (e.g. an Atmega328p etc...) into different pcb's via 'induction!!! What do you recommend? Thank you very much.

[@aberateklehaimanot9804]

superb explanation,thanks buddy.

Hi Abera, thank you for your sweet words! Wish you all the best! :-)

[@BOBANDERSON5150]

Excellent tutorial. Thanks for the video!

[@BasselTech]

+BOB ANDERSON You're welcome sir, more are coming soon. Have a great day! :-)

[@BOBANDERSON5150]

Subscribed and added your site to my Favorite. Keep up the AWESOME WORK!

[@philipslater5015]

You need a brief explanation why you are doing it the way you do. By that, I mean you are uploading a sketch/program without using a bootloader. Adding a bootloader as used by Arduino Uno for example, is a totally different process. And, no mention of which programmer to use from the Tools tab. I can see you have one selected, but you need to say why instead of skipping over it. Otherwise, a good presentation

[@BasselTech]

Thank you, Philip, for your comment. I really appreciate the advice. Wish you all the best! :-)

[@JasonRobards2]

apparentlt the programmer isn't used during a regular download.

[@valentinabastidamontiel1507]

Hi! Does this work with the internal clock of the ATmega328p only? Do yo know what changes should be made for it to work?

[@nicoteves1304]

Great tutorial! I have a question though. Is there an explanation or computation on how you come up with the values of the capacitor,resistor, crystal used?

[@BasselTech]

Dear sir, thank you a lot for your comment. The values of components used are based on the standard values provided by Arduino's website: www.arduino.cc/en/Main/Standalone However, if you're interested to know more about the maximum and minimum values for a crystal of a micro-controller chip, you can check its datasheet. ATmega328p-pu Datasheet: www.alldatasheet.com/datasheet-pdf/pdf/392289/ATMEL/ATMEGA328P-PU.html Have a great day sir! :-)

[@nicoteves1304]

Woah! Thank you very much sir! This would be a great help for my project :)

[@VeryMuchBlessed]

Very good Programming tip using USB to TTL. Please tell where you acquired your usb to ttl converter. I see several on Amazon, many different specs....?

[@dannychenski687]

Thank you!

[@t1d100]

Good information.

[@BasselTech]

Glad it was helpful!

[@Athesto]

But, does the 328p have the bootloader installed?

[@BasselTech]

Yes sir, it should have bootloader installed.

[@rodo19724]

Did you burn bootloader first into the chip,? Or is it just as it came from factory?

[@DesertVox]

Worked. Thanks.

[@BasselTech]

You're welcome! :-)

[@hunortakacs368]

Thank you so much! Dont you know what is the right way to connect batteries to these as power suppliment? I would appreciate it!

[@drshaabbas2822]

connect a battery through 5v regulator to vcc and ground of the micro controller

[@wayneswan3092]

How do you set up the IDE? what board did you use? what programmer? I can't get the cp2102 to work for nothing! keep getting 'programmer not responding", "not in sync" errors! I'm getting rather frustrated!

[@BasselTech]

May be you have a problem with the bootloader on the chip, kindly check my recent video (How To Burn Bootloader On ATmega328p Using Arduino Uno? ): kzbin.info/www/bejne/eYK6Z4Cwa7p_qMU If you still have any problems feel free to contact me at: [e-mail]

[@SMALLTECH]

CAN I PROGRAM ATMEGA328 USING ONLY RI-85 AVR USBASP PROGRAMMER????

[@mauriciogardini5175]

Genial, habia estado buscando esto por un buen tiempo, todas las soluciones para armar tu propia placa de arduino y quemar el programa incluían programadores AVR un poco costosos, siempre pensé que se podía programar con un USB to TTL de la misma forma que se programa un Arduino pro mini. Gracias por despejarme la duda, saludos.

[@BasselTech]

You're welcome! Have a nice day! :-)

[@YoYoYo]

Excuse me for the stupid question but does the Serial.println("test") output in the arduino IDE with that setup?

[@BasselTech]

Yes it will! :-)

[@t1d100]

Please state the IDE programmer configurations to use the TTL Converter.

[@iantcroft]

Thanks for the video it is very helpful. I just wanted to confirm something, (And rectify it on the video if true).... You mention connecting 10 microfarad capacitor or a 100 nanofarad capacitor to DTR On a conversion table, 100 nanofarad = 0.1 microfarad not 10 microfarad? 10 µF is equal to 10,000 nF

[@BasselTech]

Thank you sir for your comment, you're right. I meant that both of them will do the job. :-)

[@iantcroft]

Thanks for the quick reply! That's good to know you can use 0.1 microfarad, 10 microfarad and 100 nanofarad capacitors. Have got my standalone 328p put up and running now. 👍

[@BasselTech]

Sounds great, if you have any questions in the future don't hesitate to contact me. Have a great day, sir! :-)

[@JasonRobards2]

I couldn't get it to work with a 100nF ceramic, but a 10µF electrolytic like in the video did the trick.

[@BasselTech]

Glad it worked for you! Keep up the good work! :-)

[@SAM-xj9ur]

Sir can you please tell me why we use 22p F capacitor? can we use different values of capacitor also?? Plz Plz answer

[@rachit_25]

Can we say that this circuit can be used as our own arduino ????

[@BasselTech]

Yes we can!

[@rachit_25]

The serial converter is to be always connected ? Or it is for uploading the code only .

[@charislip]

What's the difference between this USB to TTL and some others with 5 pins? Is it possible to program?

[@k9gh25]

Hi, i don't have a DTR pin can i still use my ttl to program the chip?

[@jamshaidkhan5149]

Sir Is it possible that without capacitors and usb to ttl connector to make it?????

[@BasselTech]

Hi Qadeer, you can program ATmega328p using another method as in this video: Programming ATmega328p Using Arduino UNO (kzbin.info/www/bejne/e6CrdWOjaNqInqM).

[@ShopperPlug]

Does your ATmega328p already has a bootloader?

[@MasterTv_777]

My atmega328p chip has bootloader but it did not work

[@antmini1]

Thank you so much sir. :')

[@BasselTech]

You're welcome! Have a great day! :-)

[@jefflee4702]

it is comfirmed that the bootloader has installed，but the video didnt mention.

[@BasselTech]

Hi, I'm so sorry for my late reply. I'm sorry I forgot to mention that. I have a separate video showing how to burn a bootloader on ATmega328p using Arduino Uno: basseltech.com/watch?tags=Arduino&v=CQW6Mz6ULrc Have a nice day! :-)

[@biswajeetsingh4994]

Does the Chip have the Arduino bootloader pre installed?

[@Sekhar_Home]

Can we programme attiny2313 like this???

[@BasselTech]

I'm so sorry for my late reply. No, the ATtiny2313 microcontroller cannot be directly programmed using a USB-to-TTL converter. The ATtiny2313 does not have a built-in USB interface for programming. Instead, it uses a different programming interface called In-System Programming (ISP) which requires a dedicated programmer. To program the ATtiny2313, you would typically need an ISP programmer such as the USBasp or the Arduino as ISP. These programmers connect to the ISP pins of the microcontroller, allowing you to upload the firmware using specialized software like AVRDUDE. Feel free to contact me anytime if you needed any assistance. Email: [e-mail] Have a nice day! :-)

@@BasselTech thanks

[@tanyalobyam]

Do you need to make this ship with bootloader first?

[@BasselTech]

Yes sir, and if it doesn’t ship with bootloader you can follow my tutorial on how to burn a bootloader first before programming the chip. (How To Burn Bootloader On ATmega328p Using Arduino Uno?): kzbin.info/www/bejne/eYK6Z4Cwa7p_qMU

Can we use python to program ATmega328p if yes please can you tell how

[@kani_dev]

How to connect things - you can find easy in the internet you could explain why you connect to what and what are the threshoulds then the video would be usefull...

[@BasselTech]

The values of the components are documented by Arduino company. You can check their website for more details! :-)

[@shivkushwaha5356]

can i use to program for atmega328 pu not atmega 328p-PU sorry for bad English

[@BasselTech]

I think it would work, but honestly I didn't try. If you tried, please send me your feedback. Thanks! :-)

[@shivkushwaha5356]

do you know hindi language

[@BasselTech]

I am not 100% sure, but most probably it would work! :-)

[@danilosuarez117]

can you copy the program from one atmega chip to a blank new atmega chip? using usb to ttl?

[@BasselTech]

You have to upload it from your computer using Arduino IDE.

[@nicoteves1304]

What if I'm already using digital pins 0 and 1 for another component? Is there any other pin I can connect the TX/RX of the USB to TTL?

[@BasselTech]

Unfortunately sir, there aren’t other pins except pins 0 & 1 for serial communication.
