The Hardware module provides cross-platform abstractions for on-board peripherals such as GPIO and ADC.

| | ADC |
| | Analog-to-Digital Converter (ADC) interface for hardware platforms.
|
| |
| | Block I/O |
| | A block-oriented read/write/erase abstraction: storage is addressed as a fixed number of equally-sized blocks (hw_block_count, hw_block_size), rather than a flat byte stream - the natural shape for media that can only be written a block at a time and, for some backends, must be explicitly erased before it can be rewritten at all (hw_block_erase).
|
| |
| | Device I/O |
| | A bus-agnostic interface for transferring data to and from addressable devices - register reads/writes and raw transfers - without the caller needing to know whether the underlying bus is I2C, SPI, or (in future) something like an FTDI adapter.
|
| |
| | GPIO |
| | General Purpose Input/Output (GPIO) interface for hardware platforms.
|
| |
| | LED |
| | Support for controlling on-board and external LEDs.
