## SiFive device specific files

This project provides support for SiFive RISC-V microcontrollers.

## Developer info

This section is intended to developers who plan to include this library
in their own projects.

### Prerequisites

A recent [`xpm`](https://www.npmjs.com/package/xpm), which is a portable
[Node.js](https://nodejs.org/) command line application.

Compiling the source code requires a modern C++ compiler, preferably
GCC 5 or higher. 

### Easy install

This package is available as
[`@sifive/devices`](https://www.npmjs.com/package/@sifive/devices) from
the `npmjs.com` registry; with `xpm` available, installing the latest
version of the package is quite easy:

```console
$ xpm install @sifive/devices@latest
```

This package is also available from
[GitHub](https://github.com/micro-os-plus/sifive-devices-xpack):

```console
$ git clone https://github.com/micro-os-plus/sifive-devices-xpack.git sifive-devices-xpack.git
```

### How to use

The standard way to include the device files is

```c
#include <micro-os-plus/device.h>
```

### Macros

* `SIFIVE_FE310`
* `SIFIVE_E31ARTY`
* `SIFIVE_E51ARTY`

### Known problems

* the `os_terminate()` function is not fully implemented, it must
