Routing bugfix

2020-06-08T21:42:24+00:00

This CL adds a major refactor to the protocol implementation by moving away from protobuf for non-nested messages, simplifying the communications and reducing encoding/decoding overhead for both the master and slave. Smaller changes added include changes in address schemes and changes to the relevant macros to match the addressing changes. Changes by this CL have been tested to work with multiple slaves on different platforms (STM32 HAL-based and Micropython based). Documentation of the refactored protocol to specify the exact byte ordering for each message is pending.

Renamed master and slave files, small edits to code

2020-06-01T17:22:51+00:00

Added slave file, handshake to slave

2020-05-28T20:58:00+00:00

This CL adds bookkeeping structures for routing, including the routing buffer, routing index buffer, and the routing table. It also adds the main routing function, slave-side implementation of receiving subscribed data and master implementation of managed data in the routing buffer. This CL supports only routing data (branch 1) and only honors subscriptions based on module ID. CL also adds minor changes to the dataflow process, including inserting data into the routing buffer and incrementing routing pointer. CL also adds a configuration macro MASTER_I2C_BUS_INTERVAL in config.h to delay master I2C operations in order to minimize I2C timeout errors on the bus.

This CL adds structures for bookkeeping for dataflow based on the dataflow protocol. It also adds a master and slave-side implementation of a single root-to-tree path in the protocol, which involves SOR=1 (master denoting a slave send operation) and DOC=5 (slave denoting data send operation). CL includes dataflow status typedef, SOR code typedef, DOC/SOR encoding, transmitting and decoding, CTS/data encoding, transmitting and decoding.
