Functions
Convenience for accessing the on-board SPI Flash device. This powers up SERCOM3 and configures it for use as an SPI Master.
Convenience for setting up the labelled SDA, SCL pins to operate as an I2C master running at the specified frequency.
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.
Convenience for setting up the labelled RX, TX pins to operate as a UART device running at the specified baud.
