Functions

flash_spi_master

Convenience for accessing the on-board SPI Flash device. This powers up SERCOM3 and configures it for use as an SPI Master.

i2c_master

Convenience for setting up the labelled SDA, SCL pins to operate as an I2C master running at the specified frequency.

spi_master

Convenience for setting up the SPI bus on A1, A2, A3. This powers up SERCOM0 and configures it for use as an SPI Master in SPI Mode 0. Unlike the flash_spi_master function, this one does not accept a CS pin; configuring a pin for CS is the responsibility of the caller, because it could be any OutputPin, or even a pulled up line on the slave.

uart

Convenience for setting up the labelled RX, TX pins to operate as a UART device running at the specified baud.
