Modules§

  • adc
    Syscall driver capsules for ADC sampling.
  • alarm
    Tock syscall driver capsule for Alarms, which issue callbacks when a point in time has been reached.
  • button
    Provides userspace control of buttons on a board.
  • console
    Provides userspace with access to a serial interface.
  • console_ordered
    Provides userspace with access to a serial interface whose output is in-order with respect to kernel debug!() operations.
  • driver
    Mapping of capsules to their syscall driver number.
  • gpio
    Provides userspace applications with access to GPIO pins.
  • i2c_master
    SyscallDriver for an I2C Master interface.
  • i2c_master_slave_combo
    Combines two hardware devices into a single I2C master/slave device.
  • i2c_master_slave_driver
    Provides both an I2C Master and I2C Slave interface to userspace.
  • led
    Provides userspace access to LEDs on a board.
  • low_level_debug
    Provides low-level debugging functionality to userspace. The system call interface is documented in doc/syscalls/00008_low_level_debug.md.
  • process_console
    Implements a text console over the UART that allows a terminal to inspect and control userspace processes.
  • rng
    Library of randomness structures.
  • spi_controller
    Provides userspace applications with the ability to communicate over the SPI bus.
  • spi_peripheral
    Provides userspace applications with the ability to communicate over the SPI bus as a peripheral. Only supports chip select 0.
  • stream
  • test
  • virtualizers

Macros§

  • dec_consume
    The decoding equivalent of enc_consume
  • dec_try
    The decoding equivalent of enc_try. The only difference is that only an immutable borrow of the buffer is required each time.
  • enc_consume
    This is the aforementioned version of the unwrapping macro that only returns the offset.
  • enc_try
    Extracts the result of encoding/decoding (the new offset and the output) only if no errors were encountered in encoding.
  • stream_cond
    Returns an error if a condition is unmet
  • stream_done
    Returns the result of encoding/decoding
  • stream_err
    Returns an error
  • stream_from_option
    Gets the result of an Option<T>, throwing a stream error if it is None
  • stream_len_cond
    Returns a buffer length error if there are not enough bytes
