Re: Part IV: Developing Software for Your Test Application

Mr E: Thanks for the comment. A complex microcontroller application, like a car starter, obviously has multiple inputs and outputs. To really exercise the on board coding, it would be prudent to run various test scenarios, and be able to produce reports for each one. I am unsure how the testing instruments would interface to the MCU package, but I can see where one would need to be inventive. For example, if the MCU package had to drive a glow plug directly, then one would want an appropriate resistive load hooked to that output. Deriving an input from this for the testing environment might take some cobbled electronics,like a hall effect current sensor, but would be necessary for real world testing. Assuming Labview could talk to the MCU via I2C or CAN, I think most of the logic response could be captured. However, does LabView provide for individual digital I/O, analog inputs, etc? Thanks again.
