Function pyportal::spi_master

pub fn spi_master<F: Into<Hertz>>(
    clocks: &mut GenericClockController, 
    bus_speed: F, 
    sercom2: SERCOM2, 
    mclk: &mut MCLK, 
    sck: Pa13<Input<Floating>>, 
    mosi: Pa12<Input<Floating>>, 
    miso: Pa14<Input<Floating>>, 
    port: &mut Port
) -> SPIMaster2<Sercom2Pad2<Pa14<PfC>>, Sercom2Pad0<Pa12<PfC>>, Sercom2Pad1<Pa13<PfC>>>

This powers up SERCOM2 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.
