Intention is to set up entire system sending dummy data to get base programming completed prior to any functional testing.  Researched existing documents to get a reasonable base line for initial calculations and expected sensor readings.

• alpha = f(Pfwd/P45)
  • See FAA TC18-7 Fig 33 to get following formula.  Going to set up for a quadratic formula in the future even though this one is linear.

    fRatio = fPfwd/fP45;
    #define A 0.0
    #define B -16.908083
    #define C 42.415008
    fAlpha = A*fRatio*fRatio + B*fRatio + C 

• Output voltage vs Pressure from MPX10 documentation graph below.  Using linear fit at +25C gives following equation

#define A .0419
#define B -0.8279
fPSI = A*fVolts + B
