Dear Sir/Madam,

I am interested in developing with the ESP32 and need to utilize its TWAI (CAN) functionality. However, I have been unable to find the relevant documentation and functions. Could you please provide me with some examples and materials? Thank you very much for your assistance. I wish you and your family happiness and all the best.

Best regards.

Hi this is a forum for discussing the Espruino javascript environment, you probably want to look into the Espressif site/support for this: https://docs.espressif.com/projects/esp-idf/en/stable/esp32/api-reference/peripherals/twai.html

Hi - sorry, but we don't support CAN on ESP32 via Espruino at the moment. If you wanted to use it with Espruino you'd have to build your own firmware with some C code in, as shown in https://www.espruino.com/Extending+Espruino+1.

I'm afraid it's not something that is very high up our priority list for ESP32 at the moment so it's likely not something I would work on - but if someone added it and sent a PR I'm happy to merge it!

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:

That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

For syntax highlighting, surround the code block with three backticks:

```

Just like Github, a blank line must precede a code block.
