TWAI v2 missing for ESP32 C6 #10107
-
I have been working with the ESP32 C6 module and have encountered a lack of implementation for multiple TWAI drivers. According to the ESP-IDF documentation, it is possible to install multiple TWAI instances to use both TWAI0 and TWAI1 on the ESP32 C6. However, it seems that the current Arduino-ESP32 library does not yet support this v2 feature.
Attempting to configure separate TWAI interfaces fails with:
error: 'twai_handle_t' was not declared in this scope; did you mean 'twai_mode_t'?
183 | twai_handle_t twai_bus;
| ^~~~~~~~~~~~~
| twai_mode_t
Is there a timeline or planned release date for when the multiple TWAI drivers will be fully implemented for the ESP32 C6 module?

Hi @rand12345, this feature is available from ESP-IDF 5.2 version (docs for v5.1, see the warning note). The current Arduino core (3.0.X) is based on ESP-IDF v5.1. The new minor version of Arduino core (3.1.X) should be based on ESP-IDF v5.3, so in that release the feature of multiple TWAI drivers will be available.
