Compare the price and possibilities of this "expensive" to "cheap" Mega2560.
Take into account that "expensive" has a programmer / debugger. How much is the debugger for "cheap" Mega2560 and Mega328?

You think $ 20 is cheap? because I don't. As you already compare to AVR, the mythical mega2560 costs $ 6 (and this is in the small-size version of the PRO board), and I am not going into discussions about the superiority of Christmas, but I would like to remind you how much it really costs because you commonly use this argument ;)

You can always use ESP32, but it only has two 8-bit DACs.

I change successively from esp8266 to esp32, I like the "meat" ;)

There are boards for atxmega, where you have a Dac and USB programming via flip, I have a few boards myself
on atxmega128A3, extronics did that too.

Please, give a similar comparison, because you are comparing the trips with the originals, from different sources, tiles WITHOUT DEBUGER with boards with a debugger. Since the board does not have a debugger, add its price to the comparison.

The LGPL license for arduino core excludes, at least for me, the possibility of commercial use. Providing the end user with the ability to relink is too much of a hassle, if at all possible with the arduino IDE. For this libraries and components under various licenses, including GPL bootloaders.

It's as if you were comparing apples to pears, read at least once what we're talking about, if you don't understand it I'll be happy to tell you, for sure not about STM32F103RBT6 because this one has no DAC.

If you have a problem with using STMCUFinder, I can't help it.

Since you do not understand, maybe I will write more simply, can you give a link to the board with STM32 with DAC supported in Arduino? I would like to check the price, this is what is mentioned on the previous page ;)


Greetings

I do not know if the regulations allow you to put such links, but I will take the risk: https://www.aliexpress.com/item/ShengYang-STM...STM32-minimum-system-learning-board-ARM-core- board / 32911136482.html

ZTCP supported by STM32duino (this chip is on their wiki), has a 2x12bit DAC.

A great proposition for dev-boards with much higher efficiency than Blue Pill.
Here you can find documentation in better resolution than those in the auctions:
https://os.mbed.com/users/hudakz/code/STM32F407VET6_Hello/

Well, it looks great, I have to buy it for testing ;)

Greetings

I think it's a good price / performance ratio. If you use an extended instruction set, a multitude of pins, DAC, micro SD, additional FLASH memory on the board, or you simply run smaller programs from RAM so as not to get a flash By the way, it's interesting what the Chinese will declare the value of this tile. I currently have 2 ali orders behind me and they have always underestimated even this tile for $ 2. Thanks to this, the UC did not get stuck and the parcels arrived without any problems or additional costs.

I'm trying to get through this tutorial, but ...

We also set the highest jumper on the module with STM32 in the right position. We can now connect the converter to the USB port on the computer.

Which is the "topmost jumper" ??

This jumper is BOOT0, it puts the STM32 into factory UART bootloader mode.

Hello!
I am a total beginner in MC. I want to add to the Arduino IDE stm32 Blue Pill, according to the description provided here, unfortunately in the preferences it adds (I type manually, I can't paste) the link here: http://dan.drawn.org/stm32duino?..... etc. I get a "download error" message.
I don't know what I'm doing wrong. Is there any other way to add this board to the Arduino IDE?
I will be grateful for your response.
Regards.

The description at the beginning of this thread is no longer valid. At the moment, the handling of STM32 boards is much richer and, above all, officially supported by the STM company. The server that was indicated at the beginning of the thread to add to the preferences is currently turned off and your Arduino has no way to download these tiles.
To download STM32 support you have to add another address to your preferences (you can remove this old address "http: //dan.drawn.org ..."):


and then what you need will pop up in the tile manager:



Here is the current, official installation description for STM32 boards:

https://github.com/stm32duino/wiki/wiki/Getting-Started

Hello!
"rb401" - thank you for comprehensive and specific information!
Installation went smoothly.
It's a lot for me, because I spent two days trying to install stm. I looked at a lot of tutorials and videos on YT, and they all referenced this broken address.
And I will say as in the ad: "I did not know there was such a simple solution"!
Thank you.

Hello colleagues!
Once upon a time, I got very constructive help in this forum regarding STM32.
I mark I'm "green" in the subject of this MC. For several days I have been struggling with uploading the bootloader to the Blue Pill STM32F103C8T6 board. Unfortunately, the tutorials found on the web did not help me much.
Somehow (?) I was able to install the bootloader to my MC. It looks like the Blink arduino IDE is working. Receives a jakk message on an attached .jpg.
Therefore, I have a question for colleagues who are familiar with this topic: is everything ok. And can I assume that the bootloader installation was successful?
I would be grateful for a constructive reply and possible suggestions.

You did not write how you connect Blue Pill to the computer during programming, because there are several options.
It is true that I am not able to recreate your situation with me, because I personally do not care what is uploaded to Blue Pill at the time of purchase (I program via STlink) and if there was something, it is erased for me. But it seems to me that you did not manage to install the bootlader, but simply that bootloader was already uploaded by the manufacturer of the board.


Generally, for all STM32 cubes, there are three methods of saving the program to the flash memory.

Via SWD (or JTAG) signals with the help of a special programmer, most often it is STlink. In this method there is full control of the cube, plus other possibilities like debugger etc.

The second method is to use the factory-installed (by the manufacturer of the cube) bootloader. It is located in each STM32 cube and is placed outside the flash memory (in the so-called system memory), and it is not erasable. However, to run it, before resetting the cube, set the appropriate states on the BOOT pins (these two jumpers on the Blue Pill are used for this) and after programming, return to the start settings from the flash program. This bootloader offers a different set of connection methods, depending on the type of the cube, e.g. via UART (most often), USB, CAN, I2C, etc. In the case of STM32F103C8T6 specifically, there is no USB support through this bootloader. But you can via UART.

The third method is to save the flash memory with the help of a program previously loaded into the flash. So they are mostly different bootloaders, which, however, must first be loaded into the flash memory using one of the above methods.

Each of these methods has a different programming support. But Arduino provides support for these three methods. However, in the case of the third, loaded bootloader, the support applies to specific variants of the bootloaders.


So, going back to your experience and assuming that you connected Bluepill with a USB cable to your computer (and not a STlink or USB-serial adapter), you had to have previously uploaded the bootloader in the flash memory, because without it you would not be able to upload anything.
But if that was the case, it was only a matter of courtesy of the manufacturer of the tile that he uploaded it. If you are ready to go deeper into the topic of STM32, including programming new cubes, I recommend getting STlink.

"rb401" Thank you for reply. But that's not what I meant.
FTDI + Flash Loader Demo (v2.80) + loading boot20_pc13.bin + Installing USB drivers from (Arduino / hardware / Arduino_stm32 / drivers / win / instal driver, bat)
After connecting to USB, Blue Pill is recognized by the IDE on COM8.
In Win10 Device Manager as STM serial (COM8).
And I manage to upload a blink from the examples. (it takes ... a long time).
My question was whether I was able to properly install the bootloader.
I do not understand the message displayed under the sket, is there a problem with my STM?
These are my own settings (I will not list all of them now, because I don't know if it is needed), other than those found in the network.

Aaaa. So via UART, jumpers, etc. I missed this information.
That's ok. In STM32, uploading the bootloader is identical to any other standalone program, because it is basically the same. You have uploaded it, it started and it works as the author wrote it. It is difficult for me to comment on the speed of programming, because I upload programs only with STlink.
On the other hand, programs loaded by such a bootloader must be adapted to be loaded "a bit higher" in memory, because the bootloader is at the very beginning of memory. But Arduino controls it.

By the way, it is different, for example, in Atmel's uC (eg ATmega in Arduino UNO), where the bootloader is loaded at the end of the memory, it switches to start from the address at the end of memory in fusebits, but the programs are "normal". And here just installing the bootloader is not only about uploading the memory content.

I have the current version of the package for STM32 and I don't have the "STMduino bootloader" option in Upload Method, just some DFU maple.
Maybe it's some not exactly matched versions of the bootloader and support on the Arduino side.

As for the error you have on the screen that some reset did not work, it may not be important. It is important that it has been installed without errors.

Well, thank you again for the answer.
I hope that this bootloader is actually installed in my STM-e ...
The point is that he doesn't give me extra trouble. I'm an older guy now and have a hard time solving these kinds of problems.
For me, the most important thing is: "copy + paste + send to MC + run" Ready project developed by someone.
Thank you and best regards.

If Flash Loader Demonstrator did not throw an error, you have installed it correctly.
Another thing is whether you have the appropriate version of the boot20_pc13.bin file with the driver and Arduino support.

It is no longer relevant. Once upon a time the package for STM32 used the compiler for ARM processors from that package for SAM Boards and it was actually needed. But now the package for STM32 includes its compiler and that package is completely redundant.

But does this project of yours necessarily require a bootloader for some reason other than just uploading a compiled sketch from Arduino? However, because the bootloader complicates various matters (reduces the available memory, delays the start of the program, etc.), in relation to uploading only the main program.
I am asking because from Arduino you can directly save the program to Blue Pill in the same hardware way as you uploaded this bootloader with Flash Loader Demonstrator, i.e. via FTDI (or a similar adapter) to pins A9, A10, BOOT0 jumper etc.
Only that you do not use Flash Loader Demonstrator, you just select "STM32CubeProgrammer (Serial)" as Upload methods in Arduino and below you enter the COM port number of this adapter. Now I tried practically this way of uploading to Blue Pill and it works as it is supposed to work.
In order not to be too easy, before using this method in Arduino, this program must be downloaded and installed on the computer:
https://www.st.com/en/development-tools/stm32cubeprog.html
although you don't need to do anything or even run it. Arduino uses it internally.
Simple installation, no hassle. The only inconvenience is that you need to register and log in before downloading the installer. But if what, I give here an account ready not to waste time:

In fact, it takes a long time from pressing the Upload button to the end. But what I see this long time is not a matter of just uploading to the bone, but some long thinking about Arduino before starting the compilation and then processing a lot of files. And it doesn't depend on the save method you choose.
And the proper programming of the cube itself, i.e. how the red inscriptions in this bottom window are going, is a little while.
For example. With this method, through an adapter, an ordinary blink with about 22kB enters in less than 6 seconds (the same, but via STlink it enters in 1.5 seconds). So these times are bearable. You can be similarly fast by this bootloader. Just pay attention to how long these red inscriptions fly.

Yes, thank you, I will fight the ST link next. I do, but it's in a box somewhere ... still pre-packed.
I found some specific projects that I am interested in.
Unfortunately ... every project is a different MC. With Arduino ... well ... somehow with difficulty, he can cope, Now this STM ... with this bootloader "fun" I haven't uploaded anything specific to this STM except for this blast. We'll see. Then ESP32, which I plan to buy in the near future. Specifically: ESP32-DevKit C v4. I suspect that the "stairs" will begin again.
I would prefer to do everything on one particular MC model, well ... unfortunately, it is not possible, the projects I am interested in are made on different MCs.
Thanks again and best regards.
