Dear sir

I have encountered this error message while running the stm32f103 canbus program, please help

[nopnop2002]

There are five possible causes

• There is no receiving app on CanBus.
• The speed does not match the receiver.
• There is no terminating resistor on the CanBus.
• There are three terminating resistors on the CanBus.
• The resistance value of the terminating resistor is incorrect.

I was finally able to send the file, please check and help.

[nopnop2002]

Yes I can see your file.

The core you are using does not support CAN.

Read README

[saadat925]

Excuse me which readme?

[saadat925]

I can not use the blue pill board?

[nopnop2002]

https://github.com/nopnop2002/Arduino-STM32-CAN/blob/master/README.md

I can not use the blue pill board?

No.
You can use it.
But you have to change core library.

[saadat925]

Where can I find this core library?

[nopnop2002]

Software requirements
STM32 core support for Arduino.
https://github.com/stm32duino/Arduino_Core_STM32

You are using other core.

[saadat925]

Do you mean the "arduino_core_stm32_master" library?

[nopnop2002]

There is some core library for SM32.

You are using:
https://github.com/rogerclarkmelbourne/Arduino_STM32

This require:

[nopnop2002]

Follow this document
https://github.com/stm32duino/Arduino_Core_STM32

There is a lot of useful information on the internet about how to use it.

Blue-pill STM32 Programming Using ST-LINK V2 Dongle

https://idyl.io/arduino/how-to/program-stm32-blue-pill-stm32f103c8t6/

You can't use cheap stlink dongle made in China.
You need stlink-v2 dongle.

Formerly called STLink, it is now called SWD.
Both are the same.

You can use nucleo as writer.

If Roger's Bootloader is written on your BluePill,
It is necessary to connect the nSRTS pin of STLINK to the RESET pin of BluePhill.
That is the yellow line in the photo above.
Cannot write to BluePill where Roger's Bootloader is written.

Thank you sir.
