There are two common ways to set up a development environment for a microcontroller (embedded) project:
IDE - Use the integrated development environment (IDE) provided by the vendor.
CLI - Use the toolchain from the command-line (CLI), build with make (Makefile), and use your code editor of choice.
In the last video, I focused on the first approach and set up an IDE, Code Composer Studio (CCStudio). In this video, I focus on the second approach. I talk about toolchains, the advantages of building from the command-line, and show how to install a GCC-based toolchain and use it to compile the same blink LED project (MSP430) as in the last video. Finally, I create a Makefile from scratch to make building easier.

This is a great video. You've covered a topic that is usually sorely lacking in clear, accessible information. I feel like toolchains get treated as some spooky mystery that books/courses/colleagues etc just assume you know already. It's really nice to see everything demonstrated so clearly from scratch without assuming any prior information. Cheers!

@johanliebert2048 Год назад

It's very good that you describe the necessary minimum. Please continue at the same pace. First, do the minimum at which everyone in theory should start, and then more complex options with different variations. In many educational videos or books articles, either a very simple version is disassembled, or a very specific custom one. Then as a beginner, just wants to understand where to start? Should he specify this bit in the settings or not? Will this code run without the configuration of the other one? And so you have to Google and search for such questions and get a little dizmoral, since the question is very simple and easy. The question does not even require any mental intellectual abilities, it's just the specifics.

Arduino IDE supports STM32, see STM32duino. Or do you want to create your own GUI-based IDE from scratch? Yes, then you could use a GCC-based toolchain as backend, that's what the Arduino IDE is doing as far as I understand.

Hi. Can you recommend any textbooks or topics for a serious entry? There are a lot of amateur projects on the Internet, but it seems that nothing worthwhile in production will work. And also, at what level is your knowledge of circuit engineering?

@artfulbytes Год назад

Making Embedded Systems is a decent intro to the field. embeddedartistry.com and interrupt.memfault.com/ are good resources. I think the best way to learn is to come up with a project you want to build and let that guide your reading. I consider myself a beginner when it comes to circuit engineering, I can design simpler PCBs, but joining a new role soon where I'm hoping to improve in that area.

@johanliebert2048 Год назад

@@artfulbytes Would you like to make a video on the top 5 projects for people slightly above beginners in programming? It's just that there are so many videos on RU-vid on how to write code for a button or a flashing light, although it wouldn't hurt to have at least one video on how to work with ssd1602 and build some kind of game with this display. Or algorithms of records in nand nor flash memory. All the examples that I found, they are kind of simple, that is, they just write it down from above and that's it.

@artfulbytes Год назад

@@johanliebert2048 Good suggestion, I might make a video like that in the future. Right now, I'm focusing on finishing up the video series. Until then, my advice is to pick a popular arduino project and simply replace the arduino with another 8-bit microcontroller or program the atmega328p on the arduino bare-metal. Note, you may find it demotivating to spend a lot of time programming something that can be thrown together with an Arduino in mere minutes, but you got to start somewhere :)

@johanliebert2048 Год назад

@@artfulbytes Yes, I will be happy to collect projects on bare metal. It's just that sometimes my projects are not so optimal and it doesn't seem to justify itself. I think a more experienced person like you, if he shows the weak side of arduino or hal libraries, I think it will be more obvious in serious projects.

@artfulbytes Год назад

You will find that the embedded projects you do in your spare time will often not justify themselves and can often be replaced with a prototype hacked together using ready-made components and libraries. It's when you work on professional products in large quantities it truly becomes valuable and even required to incorporate more rigor. So if you want to work on embedded projects on your own, which I think you should to get into this stuff, you have to play a pretend game to some degree :) my sumobot is one big pretend game.

@BinGanzLieb 9 месяцев назад

Hello, to add the ability to program microcontrolelr without an IDE, we need debugging without an IDE. Can you make a video about debugging with gdb?

@artfulbytes 9 месяцев назад

I usually use the IDE when step-debugging, but I could perhaps make a video about how to do it with gdb from the command-line as well.

@iLuvEngineering Год назад

i keep getting an error: MSP430: Error initializing emulator: No USB FET was found. I am using an msp430g2553 on my MacBook air running macOS Monterey. I downloaded the same Ide and you did. I have tried a number of things to solve the problem but I haven't been able to solve it.

@artfulbytes Год назад

Not sure about how good the support is on Mac, I've only used Linux and windows myself. You may have to download separate drivers to get it working. Maybe these www.ti.com/tool/download/MSPDS-USB-DRIVERS/1.0.1.2

Can we still use this method if we're using a microcontroller that needs an sdk?

Yes, but how easy it is to setup from scratch will depend on the complexity of the SDK. But many SDKs come with some minimal examples to build from command line. Any particular SDK+MCU in mind?

@@artfulbytes Yeah I'm using the TI CC2640R2 with it's namesake SDK. You'll understand my want to get away from CCS but it's more dire than that, I can't get the sdk added to the linux version of CCS so I've had to use a windows VM to connect with the board

You need a specific linker script for your microcontroller, but you typically don't have to write one from scratch, because usually the vendor is kind enough to provide one, or you may copy the one from the IDE. Which microcontroller do you have?

@EEEEMMMMKKKK Год назад

This is a little bit confusing, because you are showing that you downloaded the toolchain files but than you are actually using the files from CCS.... If you download only the toolchain files you wont compile this example.

@EEEEMMMMKKKK Год назад

I figured it out, if you want to compile it without installed CCS you need to download also the "Headers and support files" from the bottom of the page where you downloaded the toolchain.

@artfulbytes Год назад

@@EEEEMMMMKKKK Yes you are completely right, sorry for the confusion! I downloaded the support headers too, but I forgot to show it in this video. I show it in another video though, ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-dh1NFAIoZCI.html.

@fededevi1985 Год назад

Don't use make in 2022 please, embedded programming is not an excuse. There are much better alternatives nowadays. CMAKE is basically the de-facto standard and most c/c++ stuff is packaged with it. Even embedded toolchains often comes with cmake configurations so you just need to point cmake to the toolchain and you can compile any cmake project with it.

@artfulbytes Год назад

I agree with you when it comes to larger projects, but for simpler ones (10s of files, single platform, and few deps), I still think make has its place.

@fededevi1985 Год назад

I did not see the last part of the video where you taked about cmake, classic youtube comment :D... But I respectfully disagree, probably I would go for cmake even for a single file.. there are so many advantages and no disadvantages over make except the added abstraction layer probably. Make have an educational value tho, especially regarding compiler/linker flags.

@hon2468 Год назад

Thank you for this amazing video! Your videos have provided a lot of insight for many embedded system beginners like me! I really appreciate it! Just one question regarding software debugging. Is there any way to debug our program in vim environment (such as breakpoints, variable and expression windows, etc.)? I would like to try embedded software development without IDE but I have trouble debugging my code.🥲

@artfulbytes Год назад

Thank you! When it comes to tasks like step-debugging that's usually when I fallback to the IDE. The debugger gdb, is available as part of the toolchain and you can run that from command-line if you want (and there might even be a plugin to integrate with vim), but I prefer an IDE for this. But I agree it's a little hassle having to switch between them.

I don't know what's wrong, but unfortunately I couldn't manage more than one file with stm32. The code is compiled. Then I make an object file out of it via objcopy but nothing further.

@artfulbytes Год назад

So the same command works when you exclude usart.c? Can you compare with the command that stm32idecube runs? Maybe it's shown in the console of the IDE? You could also try to compare the elf that stm32idecube outputs using "readelf". I don't immediately see anything wrong with your command.
