Detailed Description

template<unsigned SIZE>
class openlcb::BytesConfigEntry< SIZE >

Implementation class for internal data bytes configuration entries.

These are stored like a pascal string: the first byte is the length, the rest is the payload. The template argument is the storage size. These data elements are not rendered in the CDI in a user-visible form.
