G sensor os5000

G-Sensor – OS5000

  • Data formats:

    • Roll, Pitch, Yaw, Ax, Ay, Az

    • E.g. -78.5,7.5,300.5,-0.993,0.133,0.15

    • Ax, Ay, Az: 3 axis acceleration readings, x,y,z

  • Sample rate: 20 sample/sec

  • Reference: http://hscc.cs.nctu.edu.tw/jennic/manual/OS5000_Compass_Manual.pdf


Method of get samples

Method of get samples

  • Scenario:

  • Steps:

    1.Read sample via Uart1.

    2.Write sample to your PC(via Uart0) or sink(using wireless).

  • Set serial port of Jennic:

    • Buad rate : 19200

    • Date : 8bit

    • Parity : none

    • Stop : 1bit

Project description for bonus

Project Description(for bonus)

  • Choose a specific action and log 3-axis acceleration samples measured by some G-Sensors.

    • Golfing, batting, pitching, exercise, aerobics, stretching, …

  • Plot the corresponding waveforms.

  • Make observation and analyze the behavior of the waveforms.

  • Discuss a potential application of your results.

    • Give an example.

    • Possibly combined with existing techniques, e.g. GPS.
