Add support for STM32 Nucleo board - L432KC (and ST Nucleo L011K4)

[ghost]

It would be great to have platformio support for the Nucleo board (L432KC). At least a schematic of how to add new boards of the same family would be really helpful.

The other boards of the same Nucleo family that are supported are listed below:

1. ST Nucleo F303K8
2. ST Nucleo F031K6
3. ST Nucleo F042K6
4. ST Nucleo L031K6

Also another missing one from the same family- ST Nucleo L011K4

Thanks

stm32-l432 supported for Arduino yet?

[ghost]

@Davey3D STM32 works for mbed-os. Don't think it is supported for Arduino environment, but it should be fairly easy to add. Please follow the reference manual for adding a new board to an environment.

Thanks

STM32 is supported in the Arduino IDE :

http://www.stm32duino.com/ https://community.st.com/community/stm32-community/blog/2017/06/02/stm32-cores-enabled-in-arduino-ide https://github.com/GrumpyOldPizza/arduino-STM32L4

@Davey3D I know that STM32 has an arduino interface. I have never personally used it using Arduino code interface but only with mbed-os interface. Please try "board = stm32" and "platform= arduino" and let us know if it works.

I'm starting to realize that I'm totally lost! lol I think my confusion is stemming from the discussion linked below and some fuzziness in terms. I asked the question there as well.

My fuzzy logic went something along the lines of: platformio supports stm32-l432 boards and "Arduino" "Arduino" supports stm32-l432 boards. Therefore somehow I should be able to program my stm32-l432 using Arduino sketches. Confusion being that "Arduino" is used to refer to boards, platforms, frameworks, and IDE's if I understand correctly.

github. com/ platformio /platform-ststm32/ issues/28 (spaces added to link)

Let me ask a different way. I'd like to import my Arduino sketches into platformio and compile it to run on a stm32-l432 . What part and I'm missing and who/what/how would I get it? It looked promising as platformio lets me select the stm32-l432 board and select an option to maintain the code arduino. It generated: [env:nucleo_l432kc] platform=ststm32 board=nucleo_l432kc framework=mbed

Compiling Arduino Blink gives error : .pioenvs/nucleo_l432kc/FrameworkMbed-platform-4e964/mbed_retarget.o: In function __wrap_main': mbed_retarget.cpp:(.text.__wrap_main+0xa): undefined reference tomain'

Changing to "framework=Arduino" Error: This board doesn't support arduino framework! Changing to "platform= arduino" Error: Detected unknown package 'Arduino' Changing to "board=stm32" is unknown board.

Maybe it's not possible and I'm stuck with Arduino IDE :-(

Thanks!

Dude,

Refer here -> http://platformio.org/frameworks/arduino As you see, framework = Ardiuno should work. If it doesn't work, my best guess would be to use tool-stm32duino from here -> http://platformio.org/platforms/ststm32

If not, @ivankravets is the best person to answer.

Thanks

The package at that link only supports STM32-F series boards. I have a STM32-L which is why I installed this package as it claims STM32L. https://github.com/GrumpyOldPizza/arduino-STM32L4

I went ahead and installed the files at your link just in case. Same error:

platformio.ini

[env:nucleo_l432kc] platform=ststm32 board=nucleo_l432kc framework=Arduino

[platformio] src_dir=Blink2

platformio run l432kc; framework: Arduino)

Verbose mode can be enabled via -v, --verbose option Error: This board doesn't support Arduino framework!

Hi @Davey3D ! Unfortunately, there are few boards with Arduino support mainly because there is a plenty of different Arduino implementations for STM32 with different families. Our contributor @ubis decided to add support for this one. All STM32 boards with Arduino support you filter here http://platformio.org/boards

[Davey3D]

You mean I blew $6 on an unsupported board!? LOL It'll make a nice necklace :-) I've googled a bit but not finding much on adding/changing frameworks. I'm guessing that means it's not an easy undertaking. It's either that or get another $3 out of the piggybank for a supported board :-)

Thanks to everyone for the personal and community support :-)

@Davey3D There is an experimental/initial support for STM32L4, for the following boards:

Butterfly-L433CC, Dragonfly-L476RE, Ladybug-L432KC, ST Nucleo L432KC, ST Nucleo L476RG

in my repo. As you commented in another issue, you installed this repo, and still it didn't worked. Well, probably you installed the develoment branch. You actually need to install stm32l4_support repo.

I'm free now, so if we could move our conversation to my repo(create an issue) and solve it there, you might see official L4 support for these boards soon ;)

ubis, I just purchased three Nucleo L432KC boards to replace Arduino Mega boards for compactness.

I would like to enlist your assistance in the process to add a Nucleo L432KC board to the Arduino IDE. Thank you Paul Wilkie

[ghost]

Hi @paulw517 Could you let me know if it works with the standard Arduino IDE/package before we move it to platformio?

Thanks Chandra

Okay, I am following the instructions for installing the driver's from Zadig's download. Where is the "Boot" button on the board? The reset button is on the end of the board, button I do not see a "Boot" button??

I this referring to the Burn Bootloader button on the IDE?

[paulw517]

I am at the stage of the GrumpyOldPizza instructions under OS Specifics - Windows - OS Specific Setup

I have downloaded the Zadig.exe and I am performing the STM32 Bootloader driver setup for Tera Corp boards.

I assume the boot button is the Burn Bootloader button on the IDE? I pushed the boards reset button while highlighting the IDE’ Burn Bootloader button and the IDE returns the following error;

“Error while burning Bootloader”

Help?????

Hi @paulw517 Can you online mbed compiler and see if "Blink LED" program works ? This will give an idea on we are with your setup.

Thanks Chandra

@paulw517 This board seems to be supported by official STM32 Arduino core. You can read my comment here to try it.
