130  * The data log is recorded in the eeprom as a sequence
131  * of data packets.
132  *
133  * Each packet starts with a 4-byte header that has the
134  * packet type, the packet checksum and the tick count. Then
135  * they all contain 2 16 bit values which hold packet-specific
136  * data.
137  *
138  * For each flight, the first packet
139  * is FLIGHT packet, indicating the serial number of the
140  * device and a unique number marking the number of flights
141  * recorded by this device.
142  *
143  * During flight, data from the accelerometer and barometer
144  * are recorded in SENSOR packets, using the raw 16-bit values
145  * read from the A/D converter.
146  *
147  * Also during flight, but at a lower rate, the deployment
148  * sensors are recorded in DEPLOY packets. The goal here is to
149  * detect failure in the deployment circuits.
150  *
151  * STATE packets hold state transitions as the flight computer
152  * transitions through different stages of the flight.
