Dear sir

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

from arduino-stm32-can.

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.

Hi
I get this error message while compiling the program, please help me.

I also use this core :

You can post images to GitHub issues now. The easiest way is to copy the image (right click, Copy image) and then paste it into the text box where you describe the issue.

＞I also use this core

What core do you use?

Point me github url.

from arduino-stm32-can.

Do you have any email ?

from arduino-stm32-can.

The github problem can only be solved here.

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

from arduino-stm32-can.

Yes I can see your file.

The core you are using does not support CAN.

Read README

from arduino-stm32-can.

Excuse me which readme?

from arduino-stm32-can.

I can not use the blue pill board?

from arduino-stm32-can.

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.

from arduino-stm32-can.

Where can I find this core library?

from arduino-stm32-can.

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

You are using other core.

from arduino-stm32-can.

Do you mean the "arduino_core_stm32_master" library?

from arduino-stm32-can.

There is some core library for SM32.

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

This require:

Hi
How to add these cores in offline mode?

from arduino-stm32-can.

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.

Hi
I want to to program to board by st-link programm

er, please help with the settings.

Blue-pill STM32 Programming Using ST-LINK V2 Dongle

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.
