Families

A list of chip families currently supported by this project.

Note

The term family was chosen over platform, in order to reduce possible confusion between LibreTiny supported "platforms" and PlatformIO's "platform", as an entire package. Family is also more compatible with the UF2 term.

The following list corresponds to UF2 OTA format family names, and is also available as JSON. The IDs are also present in lt_types.h. You can view the family list by using ltchiptool list families.
