can we share the SPI bus with SDCard?

[xlla]

Description

I am using M5Stack's M5Paper base on esp32 port.
it shares the spi bus with eink panel controller it8951e and tfcard reader using two cs lines.
I can communicate it8951e use SPI bus via eink_cs.
but when I want to create a TFCard object using same SPI bus, it raise error.

SDCard(slot=3, width=1, cd=None, wp=None, sck=Pin.board.SPI_SCK, miso=Pin.board.SPI_MISO, mosi=Pin.board.SPI_MOSI,cs=Pin.board.TF_CS, freq=20000000)
Traceback (most recent call last):
  File "", line 1, in 
OSError: (-259, 'ESP_ERR_INVALID_STATE')

the micropython manual about TFCard said "SPI mode makes use of a SPI host peripheral, which cannot concurrently be used for other SPI interactions."

I thought share the SPI bus with multiply peripherals is a common demands.

I have look the implement of TFCard of esp32 port, it initialize SPI bus while choose SPI mode, can we pass in a SPI bus directly instead of just pass in mosi/miso/clk/freq etc?

No response

Implementation

I hope the MicroPython maintainers or community will implement this feature

Yes, I agree

This is unsuitable for the MicroPython bug tracker - converted to a discussion.

The official SD card driver can be used on a shared bus - see this code comment.

@peterhinch thanks a lot! I'v installed that SD card driver, it works like a charm!

and I'v learnt how to dynamic change SPI speed without deinit and init it! You've been great.
