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.

+/*
+ *  General:
+ *  Input interfaces provide inputs to functions inside test templates.  They
+ *  ONLY provide the inputs.  The output variables should be hard coded.
+ *
+ *  The input interfaces must have the following format:
+ *
+ *  ARM_xxx_INPUT_INTERFACE() or
+ *  REF_xxx_INPUT_INTERFACE()
+ *
+ *  The xxx must be lowercase, and is intended to be the indentifying substring
+ *  in the function's name.  Acceptable values are 'sub' or 'add' from the
+ *  functions arm_add_q31.
