Arduino for STM32

STM32F103C8T6 'interrupt pin' How do I use it?

1. MCU : STM32F103C8T6
2. BOOT : https://github.com/rogerclarkmelbourne/STM32duino-bootloader/blob/master/binaries/generic_boot20_pc13.bin/

I would like to use a hardware 'interrupt pin'.
I'd like to know how.
help me.

If we take Arduino as an ...

I want to create an Ethernet camera RTSP through 'STM32F4'.
ex) https://www.youtube.com/watch?v=OBXqDe1XmW8


1. Configuration: STM32F4, OV2640, W5300
2. Can I get the Arduino library file?
1) STM32F4, OV2640
2) STM32F4, W5300
3) STM32F4 - W5300 RTSP(OV2640)

If there are any experts out there ...

Thank you for quick response.

Is it possible without STM32F103 'crystal'?

hello. Nice to meet you.
Looking at the circuit diagram, we confirmed that it was implemented without a 'crystal' or 'oscillator'.

Q1) Is it possible to operate without ‘crystal’?
Q2) Is there a way to code in 'Arduino IDE'?

I wonder. help me~.

Thanks for your reply.

Core: https://github.com/rogerclarkmelbourne/Arduino_STM32
Are there any boards that work with the ‘core’ above?
Does the board you recommended have to run on a different core?

Thank you for leaving a reply.
1) I was able to find the circuit for 'F1'.
2) No circuit found for 'F4'.
Can you check?

How to make 'STM32F4xx DIY'?

hello. Nice to meet you.
1. I want to make 'STM32F4xx DIY'.
2. I want to obtain materials such as schematics and bootloaders.
3. Is it possible to get a well-organized 'url' address? help.

After searching, it seems that there is no 'Software Serial' library.

Is that right?
