Re-exports§

Modules§

  • i2c
    Use the SERCOM peripheral for I2C communications
  • spi
    Use a SERCOM peripheral for SPI transactions
  • uart
    Use the SERCOM peripheral for UART communications

Macros§

Structs§

  • GenericClockController
    GenericClockController encapsulates the GCLK hardware. It provides a type safe way to configure the system clocks. Initializing the GenericClockController instance configures the system to run at 120MHz by taking the DFLL48 and feeding it into the DPLL0 hardware which multiplies the signal by 2.5x.
  • Hertz
    Hertz
  • OneShot
    Qspi used for read/write of fixed-size octet buffers
  • Pins
    BSP replacement for the HAL Pins type
  • Qspi

Enums§

  • BaudMode
    Baudrate calculation in asynchronous mode
  • IoSet1
    Type-level variant of IoSet representing SERCOM IOSET 1
  • IoSet3
    Type-level variant of IoSet representing SERCOM IOSET 3
  • Oversampling
    Baudrate oversampling values
  • UndocIoSet2
    Type-level variant of IoSet representing an undocumented SERCOM IOSET

Constants§

Traits§

  • Periodic
    Marker trait that indicates that a timer is periodic

Functions§

  • dotstar_bitbang
    Convenience for setting up the dotstar LED using bitbang’ed SPI.
  • i2c_master
    Convenience for setting up the labelled SDA, SCL pins to operate as an I2C master running at the specified frequency.
  • qspi_master
    Convenience for setting up the onboard QSPI flash. Enables the clocks for the QSPI peripheral in single data rate mode assuming 120MHz system clock, for 4MHz QSPI mode 0 operation.
  • spi_master
    Convenience for setting up the default SPI. This powers up SERCOM1 and configures it for use as an SPI Master in SPI Mode 0.
  • uart
    Convenience for setting up the labelled RX, TX pins to operate as a UART device running at the specified baud.
