+
+The module ``TIDA010939`` is a board support driver for Texas Instruments
+TIDA-010939 reference design. It is based on the Yeti driver with similar structure
+and functionality.
+
+Communication between the TIDA010939 microcontroller and this driver module
+============================================================================
+
+The hardware connection between TIDA010939 and the host system (the board running EVerest and
+this module) is 3.3V TTL UART plus 2 GPIOs (one to reset the microcontroller
+from Linux and one to boot into the bootloader).
+
+The default configuration is 115200 bps 8N1.
+
+Protocol
+========
+
+EVerest can send commands to TIDA010939 and TIDA010939 publishes data and events back
+to EVerest. The packets are defined with protobuf to serialize the C structs
+into a binary representation that is transferred over the serial wire in a 
+stream:
+
+https://developers.google.com/protocol-buffers
+
+To be able to split the stream back into packets all data is encoded using COBS
+before it is transmitted on the UART:
+
+https://en.wikipedia.org/wiki/Consistent_Overhead_Byte_Stuffing
+
+COBS
+----
+
+COBS is implemented in ``tida_010939_comms/evSerial.cpp``. Whenever a new packet
+was extracted from the stream ``handlePacket()`` is called to decode protobuf
+and generate the corresponding signals. 
+Other parts of the module subscribe to these signals to handle the incoming 
+packets.
+
+For TX ``linkWrite`` encodes the packet with COBS and outputs it to the UART.
+
+Protobuf
+--------
+
+The actual packet definitions are located under ``tida_010939_comms/protobuf``.
+
+``tida_010939.proto`` contains all messages that can be sent from EVerest to TIDA010939 and
+all messages that TIDA010939 sends to EVerest.
+
+Refer to these files for an up to date definition as they may change 
+frequently.
+
+To generate the C code nanopb is used:
+
+``nanopb_generator -I . -D . *.proto``
+
+The output should also be manually copied to TIDA010939 Firmware to ensure the same
+definition is used on both sides when making changes.
