vuint16_t gau16RawAccels[SM_ALL_ACCEL_SIZE]

This array holds raw acceleration results for all satellites and sensors

vuint32_t gu32SMCycleStartTime

This variable is used to remember when the last SM cycle started. Should be updated in the Acquisition phase only.

vuint8_t gu8GUIStateFirstRun

This global remembers if we've been through the GUI state before
