<![CDATA[Failed to use CAN with M5Stack]]>返信: M5Stack with CAN
I tried the follow library, changed pin to GPIO17/16
https://github.com/nhatuan84/arduino-esp32-can-demo

But it does not work. I used oscilloscope to check the output from pin GPIO 17/16, There is no any output.
Could someone give me an example code that works, and a picture of connection.
Thanks!

Thank you, please inform me if you upload that sample codes.
I have another question, why there is a CAN controller MCP2515 on the extend module? Does not M5STACK include CAN controller?

I have some test program about thisCOMMU module. Recently, I'll add those example codes to m5stack's documentation.

I didnot use any extend module, only connect M5Stack to a CAN-tranceiver. Also I am going to buy that module. Could you tell me how to use that module?

Hi hayashi

I want to confirm which module you used?
Is that one?
