Status & Support

The SOL library is a work in progress; but many of its features are usable enough for inclusion in your own designs. More testing of our work – and more feedback – is always appreciated!

Support for Host Mode

The SOL library currently does not provide any support for operating as a USB host; though the low-level USB communications interfaces have been designed to allow for eventual host support. Host support is not currently a priority, but contributions are welcome.
