If I want to transfer data between an OV5642 camera (SPI) and an ST7789 display, how do I share the SPI bus?
The display_interface_spi::SPIInterface takes ownership of the SPI object, preventing me from sharing it with the OV5642, and I can not buffer the entire image (320x240 even converted to 16 bits would exceed the RAM on the Arduino Uno).

As for a workaround you can use release() to get the SPI back and sort of just juggle the around. Display interface has a release() as well which will give you the whole thing back. It's a crappy workaround tho.
