Crate capsules_core
Source - 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
- 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
