Arduino for STM32

[/quote]

Perhaps the generic system clock configuration (I'd guess for HSE with 8MHz crystal) does not suit your board.

actually this can be the problem. thank you very much. I don;y know how I forgot it. is there any especial way to config the external clock? I will look it up.

Beside that I do not know what "BJT" and "101" stands for, I think a buzzer should be supplied with a higher frequency signal, not the 1 second blink period. Try to adjust the delay sequentially down to 10 (or even 1).
What does the original BIN? Can you post a link to the board?


101 = 100 ohm ...

that's weird. I have a custom board which I'm sure is working. because when I upload the original .bin file to it, it works fine.
let me give you more details about it.
this image shows how the buzzer is connected to the STM32.

my chip is: STM32F103C8T7.
in the board manager I installed: STM32F1xx/GD32F1xx boards
in boards I select: Generic STM32F103C series.
I build it and collect the .bin file and transfer it to my chip using: SN-Link ISP V2.09.331.004n.


It didn't work for me. shouldn't I include a library for GPIO or ...

I have been using Arduino IDE to program ESP8266-07 and it worked gorgeously. now I want to use this IDE for STM32 but there is a tiny problem here. how should I address the pins which are marked in the picture. I have tried these labels for one of them and it didn't work for me: PB9, 46, D46. I got ...
