v1.0.0
======

v1.0.0 is the **initial release of the OpenMV Arduino RPC library** — an
Arduino library for controlling an OpenMV Cam (or another Arduino, or a
computer) and streaming data from it over CAN, I²C, SPI, UART (async serial),
and USB. As the first release there is nothing to migrate from; this entry
summarizes what it shipped with.

Highlights
----------

- **Remote procedure calls over any bus** — call functions on an OpenMV Cam
  from an Arduino over CAN, I²C, SPI, UART, or USB, and stream the results
  back.
- **Controller and peripheral roles** — an Arduino can drive a camera as the
  controller device, or act as a peripheral that a camera or host calls into.
- **Fault tolerant** — recovers automatically from loose wires, packet
  corruption, and timeouts.
- **Data streaming** — a streaming mode for moving large payloads such as JPEG
  frames.

New features
------------

- The RPC interface implemented across CAN, I²C, SPI, UART (async serial), and
  USB transports, with a common controller / peripheral API under the
  ``openmv`` namespace.
- A streaming mode for high-throughput transfers such as image transfer.
- Example sketches — popular features as the controller device, JPEG image
  transfer, and moving an image.
- Linux / Raspberry Pi support.

Breaking API changes
--------------------

None. v1.0.0 is the initial release — there is no prior version to break
compatibility with.
