Programming the Atmega238P
开云体育Can one of you who do this all the time advise me what minimal hardware and software is needed to do simple programming of the Atmega chip.? I already have the script I want to put in it, my main interest is just to familiarize myself with the basics with a small project and to get a useable chip out of it. Perhaps a reference to a good beginning (very beginning) tutorial.? Everything I've seen so far assumes way to much about what I already know.? They begin with acronyms and processes that are meaningless to me. Little wonder I haven't learned much yet.? There has to be someone who can teach someone like me who hasn't kept up with the pace of progress, but have a foundation in the rudiments. 73 Phil WA8YAN Sent from my Verizon, Samsung Galaxy smartphone |
开云体育The best thing about the atmel microcontrollers is that there's so many ways to work with them! The worst thing about the atmel microcontrollers is that there's so many ways to work with them!!! :-) Where to start? The easiest way ,I think, might be to get an Arduino uno or clone uno board with the socketed Atmega238P chip. You can program it and debug with the Arduino IDE and use it as is, or pop the chip out and use it bare in your other circuits. (some modes need a crystal, but stick to the internal resonator modes to start, just to make it easier) If you get additional 328p's for the board you might want to start with chips with the Arduino bootloader already on them as they are a drop in replacement on an Uno with a socket. (Some sellers are better than others at reliably indicating if they preload the bootloader, depending on the source...) But... Buy 2 Arduino uno boards, and one can be loaded with an in circuit serial programing (ICSP) program (an example script distributed with the Arduino IDE) and use it to program bare atmega chips, either with the bootloader (making them useable to load your scripts from within the ide), or your just loading your own scripts directly... (The bootloader code is bundled in with the ide) There are dedicated ICSP programmers too, but a lot of them amongst hobby community are themselves just atmega based boards... Another uno board works just as well imo, and can do double duty as another Arduino dev board... There's a series of YouTube videos from a channel called "wifi sheep" where he's making an atmega tiny basic computer, but in the series he modifies an Arduino Uno socketed board with a zif socket so he can swap chips easier as he programs them. Along the way he outlines a decent foundational method of getting started with these chips that you could build on from there... Ymmv , of course :-) Good luck! They really are a lot of fun!

Mornin' Phil: First, the disclaimer: I've written a number of programming books, so I'm going to suggest my Beginning C for Microcontrollers for consideration. Go to Amazon, look up this title, and click on the Look Inside banner near the upper-right corner of the book. This would allow you to read the Foreword, and look at the Table of Contents. Then read the reviews. I would also read the reviews of several other intro books to see if one better-suits your preferences. Since the above sounds like an ad more than being helpful, I've attached Chapter 1 from that book. It tells you how to download and install the (free) Arduino Integrated Development Environment (IDE), test the install, and write your first program. Obviously, I'm biased, but I think programming brings a new element of enjoyment to this wonderful hobby of ours. Give programming a try. I think you'll find it a fascinating tool to add to your hobby tool belt. Jack, W8TEE

I agree with Wayde that the Arduino 328P is a good place to start, but I would suggest the Nano over the Uno. The Uno does allow a lot of modules to be plugged into it, but the Nano has a much smaller footprint. Indeed, if you read current articles on using an Arduino, most use the Nano. Also, the Nano costs less. You can buy 3 Nano's for about $15 on Amazon. Do NOT buy the Nano Pro Mini. It's cheaper than an ordinary Nano, but it does not have the USB connector on it, which makes it less convenient to program. Jack, W8TEE

开云体育I like the nano a lot too. Its lower cost and smaller size makes it very project embeddable (you could sprinkle them into everything ;-) ). If the project itself doesn't need USB, I actually like the promini, myself... I have a few USB to serial cables for programing time, but now we're layering on extras again ;-) I may have read too much into the original question, but it sounded like their end goal was a standalone programmed 328p chip. For that use case, and for starters into the world of Arduino, I still like the socketed uno with the 328p in the dip package.? It's basically the original/basic Arduino experience with lots of Internet support (that can be good or bad!). The uno can wired up directly on its socket pin headers, or breadboard(or both!), and is compatible with a bunch of different 'hats' ( expansion modules/boards ) if you wanted to explore that part of the Arduino landscape. Once comfortable with the basics, there's no shortage of directions you can go from there... I actually really like the esp8266's and esp32's. Not Arduino or atmel, but really shares a lot of overlap... You can even use and program within the same Arduino environment and scripts in most cases, if you want/need. For this you get wifi and Bluetooth. But I'm getting ahead of myself again! My next direction I want to get into are all the LoRa WAN boards! Looks like a lot of fun! No matter what direction you go, there's no shortage of options, most importantly - enjoy!

I didn't understand that the OP wanted to just program the chip. I agree that the Uno would be a good choice for that, and there's lots of info on the web for doing it. The ESP32 family make me a bit nervous, mainly because of the huge variations in the boards being sold. Some have 32 pins, other 38, and a few others in between. Some of the ESP32 pins really shouldn't be used in most cases (i.e., those dedicated to external memory), while others do some weird things, especially on boot. On the plus side, it is very easy to add WiFi capability and that is often worth the hassles, plus is has a pretty deep memory pool and a reasonably fast clock. Still, for the rank beginner, I think the Uno/Nano makes more sense. Jack, W8TEE

开云体育Just to clarify, for my immediate project, yes I do simply wish to get an Atmega chip programmed to make the script I have work.? I assume the Script has to be compiled then the results uploaded to the Atmega32P. At that point I'm hoping I can put the chip in the project and be ready to run.?? Beyond that however, I am hoping to begin building my knowledge of these chips and their programming for other applications.? In the 1970's I was teaching Basic at the local junior college and in the 80's was also teaching dBase III and relational data base programming so learning C is doable.? I just gotta get the hardware down and the support software. At the present time I have several responses from folks here that i am digesting and trying to figure out where to go next.? I can't do this in one quick read though, so please have patience with me as i study what each of you have been so kind to share with me.? I appreciate all of you taking the time to help me.? As I get a grasp on the content of your responses I will be back most likely with more beginner questions.? For now.... reading and researching and cross referencing, etc. etc. Until I get it. 73 Phil WA8YAN Sent from my Verizon, Samsung Galaxy smartphone -------- Original message -------- From: "jjpurdum via groups.io" <jjpurdum@...> Date: 10/30/21 11:59 AM (GMT-05:00) Subject: Re: [QRPLabs] Programming the Atmega238P I didn't understand that the OP wanted to just program the chip.

开云体育Hi John, and all others answering my plea ! The script I have is for a morse keyer.? I am building the keyer that KL0K Thomas up in Alaska has provided the PCB for.? He is willing to program a 32P for me, but I thought I had a local ham who was knowledgeable and equipped to do it with me.... but then found out he didn't have his own hardware for the job, sooooo..... I decided to call it a learning experience and perhaps a great fall/winter project.? Thus I show up here seeking guidance to get started, first to get my chip programmed with the minimum necessary hardware and software and then to give me a push down the road to creating my own projects.? Maybe even pick up one of the books full of ham projects to try. I'm pretty sure you can teach this old dog a few new tricks.? However, that is still to be proven....

If you are just looking to upload a sketch (what the usual source files are called for the Arduino IDE) to a AVR (ATMega328P) then it is pretty simple.? The internet is full of youtube videos telling you how to do it.? There are also lots of web pages doing and showing the same thing. The simplest way is to buy a Ardunio Uno (or 2) and either a prototype board or a AVR ISP shield (what the plug in boards are called that go on the Arduino) (ebay) and load the Arduino IDE found at with the latest being version 1.8.16 for Linux, Windows, or Mac Then load your sketch (a file with a dot INO file extension) into the IDE.? From that point you can "compile" the file and upload it to the chip.? One thing that often gets new comers is that the INO may "include" a particular file (a header file usually). The "include" as it is listed in your program is telling the IDE to include that file. The issue arises when that library file that a person said to include may not be a file that you have and finding the right one becomes a headache as you will find that a file may be in lots of places on the internet with the same file name but be different files (than the one the author used).? Also you need to be aware of where your IDE puts files (including any library files you have). One thing I found disconcerting is that the IDE DEMANDS that your sketch file live in a directory with the same name as the sketch.? It will created it and although you have it stored somewhere the IDE will create a directory with that name so the fact that you had it located on say a directory of your C drive called Download it will create a directory in the IDE file path and store the sketch there.? I found that to be behavior different than most programs. Now if the file you have is a dot hex file which is a compiled version of the IDE sketch then things are done a little different but still easy to do. It is not complicated but can sometimes seem that way.? There are many on this forum and many other forums that can help you. Good luck. Jim Pruitt WA7DUY On 10/30/2021 6:25 PM, wa8yan.radio via

The internet is full of youtube videos telling you how to do it.? There are also lots of web pages doing and showing the same thing. The simplest way is to buy a Ardunio Uno (or 2) and either a prototype board or a AVR ISP shield (what the plug in boards are called that go on the Arduino) (ebay) and load the Arduino IDE found at with the latest being version 1.8.16 for Linux, Windows, or Mac Then load your sketch (a file with a dot INO file extension) into the IDE.? From that point you can "compile" the file and upload it to the chip.? One thing that often gets new comers is that the INO may "include" a particular file (a header file usually). The "include" as it is listed in your program is telling the IDE to include that file.

Also you need to be aware of where your IDE puts files (including any library files you have). One thing I found disconcerting is that the IDE DEMANDS that your sketch file live in a directory with the same name as the sketch.? It will created it and although you have it stored somewhere the IDE will create a directory with that name so the fact that you had it located on say a directory of your C drive called Download it will create a directory in the IDE file path and store the sketch there.? I found that to be behavior different than most programs. Now if the file you have is a dot hex file which is a compiled version of the IDE sketch then things are done a little different but still easy to do. It is not complicated but can sometimes seem that way.? There are many on this forum and many other forums that can help you. Good luck. Jim Pruitt WA7DUY On 10/30/2021 6:25 PM, wa8yan.radio via

I started doing these over ten years?ago, and just bought a programmer from Adafruit.? It of course was another AVR internally.? Still use it for 328P bootloaders because it's convenient.? So really if you are going to make many projects then ebaying a clone programmer for 10 bucks isn't a bad?idea. But now I buy CH340 based clone Arduino Nanos for those sort of projects instead anyway.? They are only a buck or two more than a bare DIP 328Ps are and have a bootloader on them from the Chinese factory.? ?Still terminate out to a DIP format and have the USB to serial chip and a crystal as a bonus.? Arduino IDE can just upload your code to one of those, including the programmer code (comes with the development environment) for unprogrammed chips via the ICSP pins. If you want to learn how to do this, it's a good project.? A $3-5 Nano, a solderless breadboard and a few wires and you can easily burn the bootloader on to a virgin chip.? The Arduino IDE makes all of this nearly trivial. Don't know what else to tell you, it's not rocket science. You can also buy 328P DIPs off of Amazon with the bootloader pre programmed.? I did that once at the tail end of an Amazon order to finish off a project and it was fine too.? No serial to USB that way though. Good luck.? Fred W0FMS?

开云体育Hi Jack.? ?I was just looking on Amazon for a copy of the book Soldersmoke for a Christmas present.? As I was buying that book I saw a picture of your C programming book that I remembered you recommending to me. Just thought I'd let you know that your book will be my next purchase sometime in 2022. (When the "finance director" forgets about this purchase).? Thanks for recommending it to me and for the copy of chapter 1 which I am still rereading.? Julian N4JO has taken on the daunting task of coaching me in getting the source code I have edited and compiled then loaded into my Atmega328P so my project will be up and running.? After that, I intend to move on to end up writing my own C code and your book will be my on the desk guide. Just wanted to update you on where I am at and to thank you for your taking an interest in my pursuit into the world of C. 73 Phil WA8YAN Sent from my Verizon, Samsung Galaxy smartphone -------- Original message -------- From: "jjpurdum via groups.io" <jjpurdum@...> Date: 10/30/21 9:02 AM (GMT-05:00) Subject: Re: [QRPLabs] Programming the Atmega238P Mornin' Phil: First, the disclaimer: I've written a number of programming books, so I'm going to suggest my Beginning C for Microcontrollers for consideration. Go to Amazon, look up this title, and click on the Look Inside banner near the upper-right corner of the book. This would allow you to read the Foreword, and look at the Table of Contents. Then read the reviews. I would also read the reviews of several other intro books to see if one better-suits your preferences. Since the above sounds like an ad more than being helpful, I've attached Chapter 1 from that book. It tells you how to download and install the (free) Arduino Integrated Development Environment (IDE), test the install, and write your first program. Obviously, I'm biased, but I think programming brings a new element of enjoyment to this wonderful hobby of ours. Give programming a try. I think you'll find it a fascinating tool to add to your hobby tool belt. Jack, W8TEE

Can one of you who do this all the time advise me what minimal hardware and software is needed to do simple programming of the Atmega chip.? I already have the script I want to put in it, my main interest is just to familiarize myself with the basics with a small project and to get a useable chip out of it. Perhaps a reference to a good beginning (very beginning) tutorial.? Everything I've seen so far assumes way to much about what I already know.? They begin with acronyms and processes that are meaningless to me. Little wonder I haven't learned much yet.? There has to be someone who can teach someone like me who hasn't kept up with the pace of progress, but have a foundation in the rudiments. 73 Phil WA8YAN Sent from my Verizon, Samsung Galaxy smartphone |

Not so daunting, Phil, you're a disciplined, logical thinker, and that's nine tenths of the qualifications for a good software engineer :-) Let me know if you still need that Uno I promised you: I finally found it hiding under a shield (and you now know what that is!) - right where I'd left it a couple of years ago ;-)

开云体育Yes I do.? Afraid to just buy something off amazon then find out I got the wrong thing.? So if you can spare it I will put it to good use.?? Here are a few pics of where the project stands as of now.? Notably a little more soldersmoke to make and a nice looking knob for the speed pot, oh and finally there's the issue of that blank cpu socket needing an Atmega328P.? Then it should work.
