SPI bus master in the Box #51

Closed babadue closed 1 year ago

babadue commented 1 year ago

For the Box, since the SPI LCD display is internally wired as a bus master with GPIO 7 and 6, can any other SPI peripherals be able to connect to the Box at all if the internal LCD is active?

Other SPI slave connect to the same one bus with LCD，and select by CS? I recommend not to do this, it's related to the display driver logic. if you mean the standalone SPI interface, I think it's ok.

What about an SD card in SPI mode/protocol?
