Aug. 16 Start-up Observations

Continuing to test the Forte 0.4 code with C++ rewrite of the LMS. 
Lots of time interruptions, but noticing details this time around.

Currently testing initializing all sensor ports at start-up.

  • If the start-up time is too long then the LMS is not recognized as an eCos device: 
    • Added a delay to verify the default state of the sensors before turning them off
    • With this delay device is not recognized as an eCos device
    • Without this delay it is recognized
  • LED default values:
    • LMS turned on, Sensor ports uninitialized:
      • LED on : Ports 1-3 
      • LED off : Port 4 (RS485) 
    • After Sensors initalized
      • LED on: All sensor ports
  • Sensor port seem to need to be initialized in the FBs not just AVR code (?) at least Port 4

Current Test status:  
[Note: with interruptions seems like 2 steps forward 1 step backwards]

Having problems with any called via C++ code.
