Move to Esp-idf SPI Master Driver

Are there any plans to move SPI class to esp-idf native SPI Master interface instead of the current low-level API?

ESP32

Is your feature request related to a problem?

In Tasmota we are using SPI DMA with ILI9341 driver - using Esp-idf SPI Master interface. Unfortunately there is a conflict with Arduino SPI class if the same bus is also used (typically for SDCard).

The current work-around is to make sure that DMA transfer is complete and no more transactions are in-flight.

I tried to use the W5500 Ethernet interface, which also relies on SPI Master Interface. There is no easy work-around as both APIs can't coexist on the same bus.

Describe the solution you'd like

Use spi_bus_add_device() and spi_device_transmit() APIs to communicate with SPI devices, instead of the current implementation.

Or at least use spi_device_acquire_bus() and spi_device_release_bus() to make sure there are no conflicts between the 2 APIs.

Hello @s-hadinger, thank you for opening this Feature Request.

We are aware that SPI is awaiting refactoring to use ESP-IDF API.

I'm adding your request in our Roadmap and we will investigate it.

Happy to know it's in the roadmap. I'm looking forward to this evolution.
