[E]lgeeko, a NI forum member created a VI to interface with the ez430-Chronos watch. The Chronos receiver creates a virtual serial com port on a PC. Using the NI VISA serial library, its very simple to create VIs to talk to the watch. As a test, [E]lgeeko created the following projects:

  • Simple accelerometer data graphing
  • Advanced accelerometer data graphing
  • Theramin emulator
