Location of CAN driver / example

[4okoboko]

Hello,

I am currently trying to include CAN functionality to my project.

I read about the CAN peripheral under the following link:

https://docs.espressif.com/projects/esp ... s/can.html

After reading through the documentation, I wanted to try out the examples, which according to the doc should be located under .../peripherals/can/...

But unfortunately I cannot find a 'can' folder under .../esp-idf/examples/peripherals inside my esp-idf installation.

I also cannot find the can.h header under ...esp-idf/components/driver/include/driver

My esp-idf version is I assume quite recent: 'idf.py --version' returns in terminal 'ESP-IDF v5.1-dev-1626-g4b6d9c8ad3'

I also checked the github repo for the esp-idf folder hierarchy under:

https://github.com/espressif/esp-idf/tr ... eripherals

but I still could not spot the 'can' folder.

I also tried to simply #include "driver/can.h" in my app, but I receive an error during the build process:

fatal error: driver/can.h: No such file or directory
23 | #include "driver/can.h"

I may have overlooked the CAN folders and files, but as I could not find them myself I wanted to ask where are the CAN folder and driver actually located and how can I test the CAN examples and include the CAN functionality in my app ?

Thanks in advance

Is there any ESP32 CAN module solution in terms of micropython？

Again support in this forum is VERY bad. Facing the fact that tens of thousand of developers are dealing with these great semiconductors this is really a shame. Thousands of hours of work are wasted because nobody feels responsible to answer even the simplest questions. No clue why that has to be this way !

Hi @ViennaTom,

The CAN peripheral has been renamed to TWAI.
For the background see Why rename CAN to TWAI?
