Subroutine 1, which loads the coefficients into
input locations, is called only on the first
execution following program compilation.
The temperature frequency is read on single-
ended Channel 12 and pressure is measured
on single-ended Channel 1.
Temperature, T
, D and C are computed in
0
Subroutine 2 using a generalized fourth order
polynomial equation. The form of the equation
is
F(x) = U
+ U(M
+ U(M
0
1
This form provides faster execution and greater
accuracy of the floating point math. "M
represents coefficients 0 through 4, and U is
defined above. With five coefficients, T
only parameter requiring a fourth order
polynomial. To maintain the fourth order
format, zero value "dummy" coefficients are
plugged in where required for the temperature,
D, and C coefficients.
Instructions to output the readings to Final
Storage are not included in this example.
