The SPI driver is portable, but requires significantly more
|
|
memory (1 byte of overhead per bit of pixel data).

help
|
|
The GPIO driver does bit-banging with inline assembly,
|
|
and is not available on all SoCs.
|
|
|
|
Note that this driver is not compatible with the Everlight B1414
|
|
controller.
