Event logger

Description

Logs external sensors data into a binary file marking it with local timestamps (micro-second resolution). It supports up to 4 sensor channels at the same time, e.g.: 1. IMU (Inertial Measurement Unit) - orientation in space 2. GPS - geographical location 3. External trigger signals from another Elphel camera. 4. Other sensor (e.g., odometer).

A typical log record has the following format:

[LocalTimeStamp] [SensorData]
Examples or parsed records:
IMU: [LocalTimeStamp]: [wX] [wY] [wZ]  [dAngleX] [dAngleY] [dAngleZ] [accelX] [accelY] [accelZ] [veloX] [veloY] [veloZ] [temperature]
GPS:[LocalTimeStamp]: [NMEA sentence]
SRC:[LocalTimeStamp]: [MasterTimeStamp]

Is used in Eyesis and Eyesis-4PI. Can be used with any other Elphel camera.
