Trinity Devboard PCB V1.0 Firmware. FreeRTOS is setup and the MCU reads IMU data over SPI fand Magnetometer data over I2C, each with a seperate task. Sensordata is then run though MadgwickAHRS and send over USB as serial packet data to use in trinity visualizer. Bare minimum functionality works and is replicated from the first prototype.

/**
* @defgroup GRUExample Gated Recurrent Unit Example
*
* \par Description:
* \par
* Demonstrates a gated recurrent unit (GRU) example with the use of fully-connected,
* Tanh/Sigmoid activation functions.
*
* \par Model definition:
* \par
* GRU is a type of recurrent neural network (RNN). It contains two sigmoid gates and one hidden
* state.
* \par
* The computation can be summarized as:
* <pre>z[t] = sigmoid( W_z &sdot; {h[t-1],x[t]} )
* r[t] = sigmoid( W_r &sdot; {h[t-1],x[t]} )
* n[t] = tanh( W_n &sdot; [r[t] &times; {h[t-1], x[t]} )
* h[t] = (1 - z[t]) &times; h[t-1] + z[t] &times; n[t] </pre>
* \image html GRU.gif "Gate Recurrent Unit Diagram"
*
* \par Variables Description:
* \par
* \li \c update_gate_weights, \c reset_gate_weights, \c hidden_state_weights are weights corresponding to update gate (W_z), reset gate (W_r), and hidden state (W_n).
* \li \c update_gate_bias, \c reset_gate_bias, \c hidden_state_bias are layer bias arrays
* \li \c test_input1, \c test_input2, \c test_history are the inputs and initial history
*
* \par
* The buffer is allocated as:
* \par
* | reset | input | history | update | hidden_state |
* \par
* In this way, the concatination is automatically done since (reset, input) and (input, history)
* are physically concatinated in memory.
* \par
* The ordering of the weight matrix should be adjusted accordingly.
*
*
