Add portduino platform, encode SPI device in spi_host #561

Closed jp-bennett closed 6 months ago

jp-bennett commented 7 months ago

@mverch and I hashed out the SPI device problem, and what we came up with was a scheme to encode the SPI bus as the lower 4 bits of spi_host, and the device as the upper 4 bits. The change on the Portduino side was to make sure that multiple HardwareSPI objects could be created, and safely point to the same device.

Much simpler, moved the gnarly bits down into the Portduino layer. Also unified the approach between the touch and panel SPI layers.

Looks better now :)

@tobozo what do we think about this approach?

@jp-bennett much lighter, less is more :+1:
@mverch67 thanks for helping with the review :heart:
