SPI¶
The Serial Peripheral Interface Bus (SPI) is a serial data transfer protocol useful for interacting with a wide variety of hardware peripherals.
The Maple has two SPI ports. The first has NSS on D10, MOSI on D11, MISO on D12, and SCK on D13. The second has NSS on D31, SCK on D32, MISO on D33, and MOSI on D34.
The public libmaple API for managing the SPI ports is the HardwareSpi class.
