Variable Documentation

const uint16_t cau16CACrashThresholds[]

Chart showing thresholds per Central Accelerometer

const uint16_t cau16PSI5CrashThresholds[]

Chart showing thresholds per PSI5 satellite

const uint8_t cau8SatelliteDetectionDirection[]

Chart correlating PSI5 satellites vs. Central accelerometer direction

const uint8_t cau8SatToSquibs[]

Chart correlating squibs to confirmed satellites

const uint8_t cu8SizeOfSatToSquibs

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
