IDF V3.2 with CAN driver

Postby snahmad75 » Tue Oct 23, 2018 9:01 am

When are you going to release first stable version 3.2 of ESP-IDF which will include can driver.

We have tested CAN driver it is working. Can you verify any unit test is not working against latest source of ESP-IDF. I am using latest code. any breaking changes let me know.

We are doing into production in 1 month time.

Thanks,
Naeem

Hi Naeem,

I've split this post into a new thread as it's a different question to the original thread.

I'm afraid we don't have an ETA for ESP-IDF V3.2 yet, but it will be more than one month away. There should be a v3.2 beta release around the end of November.

All master branch updates on GitHub have passed all enabled automated tests, including unit tests. There are no unit tests for the CAN driver however there are 3 integration "example tests" for the 3 example CAN projects.

Compared to stable release versions the master branch revisions have not had any manual testing done on them (apart from developer testing).

Hello,

this is good news to have an 'official' can driver available.
Saw the documentation in the 3.2 programming guide, also the examples, but there is nothing in Terms of CAN-bus peripherials in the main ESP32 data sheet. (looking specially for further info like possible GPIOs through the GPIO Matrix for CAN..) Does Espressif intend to add some documentation for this? Except unofficial info snippets like the base adress and the Information that it is SJA1000-compatible I find nothing about can Registers and peripherial descriptions. Or do I miss something?

thanks

Juergen

Yes, a TRM chapter for this peripheral is planned, however at the moment it is of a relatively low priority, so I can't give you any timeline.

Hi,

Would you please let me know that how you are using CAN driver and with which device? How you are testing CAN device with ESP32?

It will be good if you provide few information for that.

Yes using latest CAN Driver from version=3.2 with wrover Module -B. We improve and customise can driver driver code using our own circular buffer.
Wrote simple program to transmit can messages continuous. to receive can messages we integrate into our main application. cannot share code. not open source. What you want to know more.
